Phase Transitions in Particle Physics -- Results and Perspectives from Lattice Quantum Chromo-Dynamics
Gert Aarts, Joerg Aichelin, Chris Allton +38
Phase transitions in a non-perturbative regime can be studied by ab initio Lattice Field Theory methods. The status and future research directions for LFT investigations of Quantum…
Kokkos-Based Implementation of MPCD on Heterogeneous Nodes
Rene Halver, Christoph Junghans, Godehard Sutmann
The Kokkos based library Cabana, which has been developed in the Co-design Center for Particle Applications (CoPA), is used for the implementation of Multi-Particle Collision Dynam…
Topological features of the deconfinement transition
Sz. Borsanyi, Z. Fodor, D. A. Godzieba +4
The first order transition between the confining and the center symmetry breaking phases of the SU(3) Yang-Mills theory is marked by discontinuities in various thermodynamics funct…
Wigner Distribution Deconvolution Adaptation for Live Ptychography Reconstruction
Arya Bangun, Paul F. Baumeister, Alexander Clausen +2
We propose a modification of Wigner Distribution Deconvolution (WDD) to support live processing ptychography. Live processing allows to reconstruct and display the specimen transfe…
Phenomenological modeling of diverse and heterogeneous synaptic dynamics at natural density
Agnes Korcsak-Gorzo, Charl Linssen, Jasper Albers +9
This chapter sheds light on the synaptic organization of the brain from the perspective of computational neuroscience. It provides an introductory overview on how to account for em…
On the experimental verification of the uncertainty principle of position and momentum
Thomas Schürmann, Ingo Hoffmann, Winfrid Görlich
Historically, Kennard was the first to choose the standard deviation as a quantitative measure of uncertainty, and neither he nor Heisenberg explicitly explained why this choice sh…
Unbalanced penalization: A new approach to encode inequality constraints of combinatorial problems for quantum optimization algorithms
Alejandro Montanez-Barrera, Dennis Willsch, Alberto Maldonado-Romo +1
Solving combinatorial optimization problems of the kind that can be codified by quadratic unconstrained binary optimization (QUBO) is a promising application of quantum computation…
On the fragility of gate-error metrics in simulation models of flux-tunable transmon quantum computers
Hannes Lagemann, Dennis Willsch, Madita Willsch +3
Constructing a quantum computer requires immensely precise control over a quantum system. A lack of precision is often quantified by gate-error metrics, such as the average infidel…
Orbital magnetoelectric effect in nanoribbons of transition metal dichalcogenides
Tarik P. Cysne, Filipe S. M. Guimarães, Luis M. Canonico +3
The orbital magnetoelectric effect (OME) generically refers to the appearance of an orbital magnetization induced by an applied electric field. Here, we show that nanoribbons of tr…
On the hardness of quadratic unconstrained binary optimization problems
Vrinda Mehta, Fengping Jin, Kristel Michielsen +1
We use exact enumeration to characterize the solutions of quadratic unconstrained binary optimization problems of less than 21 variables in terms of their distributions of Hamming…
Sustaining Rabi oscillations by using a phase-tunable image drive
H. De Raedt, S. Miyashita, K. Michielsen +3
Recent electron spin resonance experiments on CaWO:Gd and on other magnetic impurities have demonstrated that sustained Rabi oscillations can be created by driving a mag…
Folding lattice proteins with quantum annealing

Quantum annealing is a promising approach for obtaining good approximate solutions to difficult optimization problems. Folding a protein sequence into its minimum-energy structure…
Topological properties of minimally doubled fermions in two space-time dimensions
Stephan Dürr, Johannes H. Weber
The two-dimensional Schwinger model is used to explore how lattice fermion operators perceive the global topological charge of a given background gauge field. We…
Exploring hyper-parameter spaces of neuroscience models on high performance computers with Learning to Learn
Alper Yegenoglu, Anand Subramoney, Thorsten Hater +7
Neuroscience models commonly have a high number of degrees of freedom and only specific regions within the parameter space are able to produce dynamics of interest. This makes the…
