The Strangeness Content of the Nucleon

The Strangeness Content of the Nucleon

At the Large Hadron Collider at CERN protons are collided at extremely high energies in an effort to detect New Physics, i.e. deviations from Standard Model expectations. These depend on the structure of the colliding protons, and this is largely determined by quantum fluctuations, e.g., by how much of the proton is made up of short lived quark-antiquark pairs. At present the mass fractions are controversial both for light (up, down) and for strange quarks. These (and related) quantities are calculated within Quantum Chromodynamics. The partial results obtained so far hint at inconsistencies of present parametrizations.

Computational Characterization of Structural Dynamics and Interactions Underlying the Function of Transmembrane Domains of Integral Membrane Proteins

Computational Characterization of Structural Dynamics and Interactions Underlying the Function of Transmembrane Domains of Integral Membrane Proteins

Integral membrane proteins exhibit conformational flexibility at different structural levels and time scales. Our work focusses on the biophysical basis of the interdependence of transmembrane helix dynamics, helix-helix recognition, and helix-lipid interactions. In this context, we try to understand the impacts of these phenomena on biological processes, such as membrane fusion, lipid translocation, and intramembrane proteolysis. Our approach closely connects experimental work and established computational analysis in order to interpret and guide the experiments and to validate the simulations.

Nucleon Observables as Probes for Physics Beyond the Standard Model

Nucleon Observables as Probes for Physics Beyond the Standard Model

Utilizing the approach of lattice QCD, physicists computed key observables with the goal to better understand the inner structure of nucleons. This project addressed in particular the quark and gluon contributions to the spin, the angular momentum, and the momentum of the nucleon while a special focus was laid on the calculation of the scalar quark content of the proton. Such calculations will aid research of physical processes in particle physics and the as yet unknown nature of dark matter.

Binary Neutron Star Mergers

Binary Neutron Star Merger Simulations

The recent observations of gravitational waves (GWs) marked a breakthrough and inaugurated the field of GW astronomy. To extract information from a detection, the measured signal needs to be cross-correlated with a template family. However, due to the nonlinearity of Einstein’s equations, numerical simulations have to be used to study systems with gravitational fields strong enough to emit GWs. This project focused on the simulation of systems consisting of two neutron stars and investigated the effect of the mass ratio and the influence of the spin of the individual stars.

Precession Driven Flows in Planets

Precession Driven Flows in Planets

Researchers at the University of Münster investigated precession driven flows in planets by direct numerical simulations on the JUQUEEN cluster. Precession of the rotation axis is an often neglected driving mechanism for flows in planetary cores, a field of research were other scientists mainly focus on the influence of thermal or chemical effects. As an additional complication that moves the models closer to the physical reality, the project considered the spheroidal shape of the planet, whereas previous research has been focused on the idealized case of a perfect sphere.

Buoyant-Convectively Driven Heat and Ggas Exchange

Buoyant-Convectively Driven Heat and Gas Exchange

Gas exchange across water surfaces receives increasing attention because of its importance to the global greenhouse budget. At present, most models used to estimate the gas flux only consider wind-shear. To improve the accuracy of the predictions a detailed study of buoyancy-driven gas transfer, which is a major contributor at low to moderate wind-speed, is necessary.  The main challenge lies in resolving the extremely thin gas concentration boundary layer. To address this, direct numerical simulations (DNS) of gas transfer induced by surface-cooling were performed on SuperMUC using a numerical scheme that is capable of resolving the thin diffusive layers on a relatively coarse mesh while avoiding spurious oscillations of the scalar quantity.

EXASTEEL - Bridging Scales for Multiphase Steels

EXASTEEL - Bridging Scales For Multiphase Steels

The project EXASTEEL is concerned with parallel implicit solvers for multiscale problems in structural mechanics discretized using finite elements. It is focussed on modern high strength steel materials. The higher strength and better ductility of these materials largely stems from the carefully engineered grain structure at the microscale. The computational simulations used therefore take into account the microstructure, but without resorting to a brute force discretization (which will be out of reach for the foreseeable future). The researchers' approach combines a computational multiscale approach well known in engineering (FE) with state-of-the-art parallel scalable iterative implicit solvers developed in mathematics.

GRSimStar - General Relativistic Simulations of Binary Neutron Star Mergers

GRSimStar - General Relativistic Simulations of Binary Neutron Star Mergers

What can we learn from some of the most powerful explosions in the universe? Researchers in Italy, USA, and Japan joined forces to study, via computer simulations in general relativity, what happens when two neutron stars in a binary system finally merge. Besides black holes, neutron stars are the most compact objects ever observed. Their collisions can produce bright electromagnetic emission and strong gravitational waves. Understanding how to relate the different signals with the properties of neutron stars may allow us to understand how matter behaves in conditions so extreme that cannot be reproduced on Earth.

Crystallization of Amorphous Phase Change Memory Material: Molecular Dynamics Simulations

Crystallization of Amorphous Phase Change Memory Material: Molecular Dynamics Simulations

Rewritable optical storage media, such as the digital versatile disk (DVD-RW) and Blu-Ray Disc, are based on the extremely rapid and reversible crystallization of amorphous “bits” in thin polycrystalline layers of special alloy materials. The ultimate limit to the speed (and therefore usefulness) of such devices is the speed of crystallization of the amorphous structure, and the nature of the process has been the subject of much speculation. Insight is provided by simulations of crystallization of an amorphous alloy of germanium, antimony, and tellurium (GST) that is widely used as a component of commercial optical memories.

DNS of Turbulent Oxy-Fuel Flames

Direct Numerical Simulation of Turbulent Oxy-Fuel Flames

The direct numerical simulation performed in the course of this project – run on SuperMUC at LRZ – investigated a temporally evolving non-premixed syngas jet flame. Results of this simulation were used to validate a recently published set of extended model equations for the reaction zone dynamics in non-premixed combustion. Furthermore, the dataset was used to analyze the importance of curvature induced transport phenomena. Regions could be identified where curvature has a significant impact on the flame structure.

Steering Complex Chemical Reactions by Mechanical Forces

Steering Complex Chemical Reactions by Mechanical Forces

Disulfide bonds are known to stabilize protein structures by imposing covalent cross-links. More recently they have been found to regulate protein activity as well by undergoing chemical reactions themselves. However, the chemistry of disulfide bond cleavage reactions is astonishingly rich and includes also β-elimination reactions in alkaline solution instead of the usual nucleophilic substitution at one of the sulfur atoms. Using HPC system JUQUEEN, an international team of scientists computationally studied both reaction channels as a function of increasingly large mechanical forces.

Hydrangea: Simulating the Formation of Galaxies in Clusters

Why do galaxies that live in the enormous structures known as galaxy clusters look different from normal, isolated galaxies, like our Milky Way? To answer this question, astrophysicists have created the Hydrangea simulations, a suite of 24 high-resolution cosmological hydrodynamical simulations of galaxy clusters. Containing over 20,000 cluster galaxies in unprecedented detail and accuracy, these simulations are giving astrophysicists a powerful tool to understand how galaxies have formed and evolved in one of the most extreme environments of our Universe.

2+1+1 Lattice QCD Calculations With HEX Smeared Clover Fermions

2+1+1 Lattice QCD Calculations With HEX Smeared Clover Fermions

The theories of Dark Matter (DM) are formulated in terms of couplings between DM particles and quarks, the elementary particles that build up protons and neutrons. To calculate the prediction of these theories and aid the experimental searches, one has to know the "quark content" of the nucleon, which is roughly speaking the probability of finding quarks in the nucleon. To calculate the nucleon quark content, an international team of researchers performed highly demanding computations on HPC system JUQUEEN of JSC.

Modulation of Turbulent Properties in a Spray Flame Burning n-Heptane

Modulation of Turbulent Properties in a Spray Flame Burning n-Heptane: Direct Numerical Simulation

Spray evaporation and burning in a turbulent environment is a configuration found in many practical applications, such as diesel engines, direct-injection gasoline engines, gas turbines, etc. Understanding the physical process involved in this combustion process will help improving the combustion efficiency of these devices and, therefore, reduce their emissions. Direct numerical simulation (DNS) is a very attractive tool to investigate in all details the underlying processes since it is able to capture and resolve all scales in the system. In this project, evaporation, ignition, and mixing are investigated in both temporally- and spatially-evolving jets, using DNS.

Turbulent Convection at Very Low Prandtl Numbers

In many turbulent convection flows in nature and technology the thermal diffusivity is much higher than the kinematic viscosity which means that the Prandtl number is very low. Laboratory experiments in very low-Prandtl-number convection have to be conducted in liquid metals which are inaccessible for laser imaging techniques and require analysis by ultrasound or X-rays. Researchers of the TU Ilmenau and the Occidental College Los Angeles ran direct numerical simulations of this regime of turbulent convection at high Rayleigh numbers to reveal the full 3D structure of temperature and velocity fields.

APAM – Aquatic Purification Assisted by Membranes

APAM – Aquatic Purification Assisted by Membranes

The electro-dialysis process is an efficient desalination technique that uses ion exchange membranes to produce clean water from seawater. This process involves different physical phenomena like fluid dynamics, electrodynamics and diffusive mass-transport along with their interactions. Rigorous assessment of those interactions, especially those near the membranes, are only possible through large-scale coupled simulations. The aim of the APAM compute time project is the detailed flow simulation in this application to understand the effect of different spacer structures between the membranes in this process.

3D NLTE (non-local thermodynamic equilibrium) Radiation Transport with PHOENIX/3D

3D NLTE Radiation Transport with PHOENIX/3D

Understanding the light emitted by (magnetically) active cool stars (‘M dwarfs’) is a major challenge for astrophysics. In this project, scientists use their PHOENIX/3D code to simulate the light emitted by a ‘box’ inside the outer layers of an active M dwarf in detail. The temperatures and pressures inside the box are taken from an existing gas dynamics simulation (including magnetic field effects) by S. Wedemeyer (Oslo). The computational requirements of detailed non-equilibrium 3D radiative transfer simulations are staggering and require the largest supercomputers on Earth.

Composite Higgs Theory Beyond the Standard Model

Composite Higgs Theory Beyond the Standard Model

Despite the remarkable success of the Standard Model (SM), it is generally believed that there are phenomena beyond it. One class of Beyond Standard Model (BSM) theories postulates that the observed Higgs boson is indeed a composite particle composed of new subatomic particles bounded by new interactions. In this project, the Lattice Higgs Collaboration (LatHC) investigates the properties of the Sextet model including hadron spectroscopy and how interaction strength varies with probing energy. These findings have recently made the Sextet model one of the highly interesting BSM models.
