Predictive tracking of the NV Center based on external temperature sensors
Manpreet Singh Jattana, Thomas Lippert
We report an experimental design where the position and resonance frequency of the Nitrogen Vacancy (NV) in a diamond are correlated with the room temperature. A simple model train…
Universal Quantum Computer Simulation of 50 Qubits on Europe`s First Exascale Supercomputer Harnessing Its Heterogeneous CPU-GPU Architecture
Hans De Raedt, Jiri Kraus, Andreas Herten +5
We have developed a new version of the high-performance Jülich universal quantum computer simulator (JUQCS-50) that leverages key features of the GH200 superchips as used in the J…
Topology of dynamical lattice configurations including results from dynamical overlap fermions
Falk Bruckmann, Nigel Cundy, Florian Gruber +2
We investigate how the topological charge density in lattice QCD simulations is affected by violations of chiral symmetry caused by the fermion action. To this end we compare latti…
Room Temperature Dy Spin-Flop Switching in Strained DyFeO3 Thin Films
Banani Biswas, Federico Stramaglia, Ekatarina V. Pomjakushina +3
Epitaxial strain in thin films can yield surprising magnetic and electronic properties not accessible in bulk. One materials system destined to be explored in this direction are or…
Lattice QCD at the physical point meets SU(2) chiral perturbation theory
Stephan Durr, Zoltan Fodor, Christian Hoelbling +9
We perform a detailed, fully-correlated study of the chiral behavior of the pion mass and decay constant, based on 2+1 flavor lattice QCD simulations. These calculations are implem…
Recent development and perspectives of machines for lattice QCD
Thomas Lippert
I highlight recent progress in cluster computer technology and assess status and prospects of cluster computers for lattice QCD with respect to the development of QCDOC and apeNEXT…
