Magnetized Current Filaments as a Source of Circularly Polarized Light
U. Sinha, J. Martins, J. Vieira +3
We show that the Weibel or currente filamentation instability can lead to the emission of circularly polarized radiation. Using particle-in-cell (PIC) simulations and a radiation p…
Creating retrogradely orbiting planets by prograde stellar fly-bys
Andreas Breslau, Susanne Pfalzner
Several planets have been found that orbit their host star on retrograde orbits (spin-orbit angle ϕ > 90°). Currently, the largest measured projected angle between the orbital angu…
A Structured Approach to the Construction of Stable Linear Lattice-Boltzmann Collision Operators
Philipp Otte, Martin Frank
We introduce a structured approach to the construction of linear BGK-type collision operators ensuring that the resulting Lattice-Boltzmann methods are stable with respect to a wei…
scattering and the resonance in 2+1 flavor QCD
Gumaro Rendon, Luka Leskovec, Stefan Meinel +6
In this project, we will compute the form factors relevant for decays. To map the finite-volume matrix elements computed on the lattice to the infi…
PennyLane: Automatic differentiation of hybrid quantum-classical computations
Ville Bergholm, Josh Izaac, Maria Schuld +65
PennyLane is a Python 3 software framework for differentiable programming of quantum computers. The library provides a unified architecture for near-term quantum computing devices,…
Magnetization and energy dynamics in spin ladders: Evidence of diffusion in time, frequency, position, and momentum
Jonas Richter, Fengping Jin, Lars Knipschild +5
The dynamics of magnetization and energy densities are studied in the two-leg spin-1/2 ladder. Using an efficient pure-state approach based on the concept of typicality, we calcula…
Shape optimization for interior Neumann and transmission eigenvalues
Andreas Kleefeld
Shape optimization problems for interior eigenvalues is a very challenging task since already the computation of interior eigenvalues for a given shape is far from trivial. For exa…
On the self-similarity of line segments in decaying homogeneous isotropic turbulence
Michael Gauding, Lipo Wang, Jens Henrik Goebbert +3
The self-similarity of a passive scalar in homogeneous isotropic decaying turbulence is investigated by the method of line segments (M. Gauding et al., Physics of Fluids 27.9 (2015…
Opposite-Parity Contaminations in Lattice Nucleon Form Factors
Finn M. Stokes, Waseem Kamleh, Derek B. Leinweber
The recently-introduced Parity Expanded Variational Analysis (PEVA) technique allows for the isolation of baryon eigenstates at finite momentum free from opposite-parity contaminat…
Applying constrained simulations for low temperature lattice QCD at finite baryon chemical potential
G. Endrodi, Z. Fodor, S. D. Katz +3
We study the density of states method as well as reweighting to explore the low temperature phase diagram of QCD at finite baryon chemical potential. We use four flavors of stagger…
Complex Langevin and boundary terms
Manuel Scherzer, Erhard Seiler, Dénes Sexty +1
As is well known the Complex Langevin (CL) method sometimes fails to converge or converges to the wrong limit. We identified one reason for this long ago: insufficient decay of the…
Searching for a CEP signal with lattice QCD simulations
Zoltan Fodor, Matteo Giordano, Jana N. Guenther +7
We discuss the reliability of available methods to constrain the location of the QCD critical endpoint with lattice simulations. In particular we calculate the baryon fluctuations…
Tools for Analyzing Parallel I/O
Julian M. Kunkel, Eugen Betke, Matt Bryson +5
Parallel application I/O performance often does not meet user expectations. Additionally, slight access pattern modifications may lead to significant changes in performance due to…
Lattice-based QCD equation of state at finite baryon density: Cluster Expansion Model
V. Vovchenko, J. Steinheimer, O. Philipsen +4
The QCD equation of state at finite baryon density is studied in the framework of a Cluster Expansion Model (CEM), which is based on the fugacity expansion of the net baryon densit…
The SAGE Project: a Storage Centric Approach for Exascale Computing
Sai Narasimhamurthy, Nikita Danilov, Sining Wu +8
SAGE (Percipient StorAGe for Exascale Data Centric Computing) is a European Commission funded project towards the era of Exascale computing. Its goal is to design and implement a B…
Roberge-Weiss endpoint and chiral symmetry restoration in QCD
Claudio Bonati, Enrico Calore, Massimo D'Elia +6
We investigate the fate of the Roberge-Weiss endpoint transition and its connection with the restoration of chiral symmetry as the chiral limit of QCD is approached. We…
Diattenuation Imaging reveals different brain tissue properties
Miriam Menzel, Markus Axer, Katrin Amunts +2
When transmitting polarised light through histological brain sections, different types of diattenuation (polarisation-dependent attenuation of light) can be observed: In some brain…
Finite-Difference Time-Domain simulations of transmission microscopy enable a better interpretation of 3D nerve fiber architectures in the brain
Miriam Menzel, Markus Axer, Hans De Raedt +5
In many laboratories, conventional bright-field transmission microscopes are available to study the structure and organization principles of fibrous tissue samples, but they usuall…
ChASE: Chebyshev Accelerated Subspace iteration Eigensolver for sequences of Hermitian eigenvalue problems
Jan Winkelmann, Paul Springer, Edoardo Di Napoli
Solving dense Hermitian eigenproblems arranged in a sequence with direct solvers fails to take advantage of those spectral properties which are pertinent to the entire sequence, an…
Higher order fluctuations and correlations of conserved charges from lattice QCD
Szabolcs Borsanyi, Zoltan Fodor, Jana N. Guenther +5
We calculate several diagonal and non-diagonal fluctuations of conserved charges in a system of 2+1+1 quark flavors with physical masses, on a lattice with size . Hig…
Separation of conditions as a prerequisite for quantum theory
Hans De Raedt, Mikhail I. Katsnelson, Dennis Willsch +1
We introduce the notion of "separation of conditions" meaning that a description of statistical data obtained from experiments, performed under a set of different conditions, allow…
Testing quantum fault tolerance on small systems
D. Willsch, M. Willsch, F. Jin +2
We extensively test a recent protocol to demonstrate quantum fault tolerance on three systems: (1) a real-time simulation of five spin qubits coupled to an environment with two-lev…
