Digitizing SU(2) Gauge Fields and What to Look Out for When Doing So

Tobias Hartung, Timo Jakobs, Karl Jansen +2

With the long term perspective of using quantum computers and tensor networks for lattice gauge theory simulations, an efficient method of digitizing gauge group elements is needed…

Spectroscopy in the 2+1 Thirring Model with Domain Wall Fermions

Simon Hands, Johann Ostmeyer

We employ the domain wall fermion (DWF) formulation of the Thirring model on a lattice in 2+1+1 dimensions and perform flavor Monte Carlo simulations. At a critical interacti…

Optimised Trotter Decompositions for Classical and Quantum Computing

Johann Ostmeyer

Suzuki-Trotter decompositions of exponential operators like are required in almost every branch of numerical physics. Often the exponent under consideration has to be sp…

Defining Canonical Momenta for Discretised SU(2) Gauge Fields

Marco Garofalo, Tobias Hartung, Karl Jansen +3

In this proceeding contribution we discuss how to define canonical momenta for SU(N) lattice gauge theories in the Hamiltonian formalism in a basis where the gauge field operators…

Real Time Simulations of Quantum Spin Chains: Density-of-States and Reweighting approaches

Pavel Buividovich, Johann Ostmeyer

We put the Density-of-States (DoS) approach to Monte-Carlo (MC) simulations under a stress test by applying it to a physical problem with the worst possible sign problem: the real…

Mitigating the Hubbard Sign Problem with Complex-Valued Neural Networks

Marcel Rodekamp, Evan Berkowitz, Christoph Gäntgen +3

Monte Carlo simulations away from half-filling suffer from a sign problem that can be reduced by deforming the contour of integration. Such a transformation, which induces a Jacobi…

PLANETAMOS, A Physics Show Musical (Phyusical)

Lara Becker, Erik Busley, Jakob Dietl +21

We present a physics show musical with live physics experiments and live performed songs with live orchestral accompaniment. The musical was first put on stage in German at the Phy…

Digitising SU(2) Gauge Fields and the Freezing Transition

Tobias Hartung, Timo Jakobs, Karl Jansen +2

Efficient discretisations of gauge groups are crucial with the long term perspective of using tensor networks or quantum computers for lattice gauge theory simulations. For any Lie…
