Fermion Discretization Effects in the Two-Flavor Lattice Schwinger Model: A Study with Matrix Product States
Tim Schwägerl, Karl Jansen, Stefan Kühn
We present a comprehensive tensor network study of staggered, Wilson, and twisted mass fermions in the Hamiltonian formulation, using the massive two-flavor Schwinger model as a be…
(2+1)D quantum electrodynamics at finite density on a quantum computer
Emil Otis Rosanowski, Arianna Crippa, Lena Funcke +3
In this paper, we explore (2+1)D quantum electrodynamics (QED) at finite density on a quantum computer, including two fermion flavors. Our method employs an efficient gauge-invaria…
Analysis of the confinement string in (2 + 1)-dimensional Quantum Electrodynamics with a trapped-ion quantum computer
Arianna Crippa, Karl Jansen, Enrico Rinaldi
Compact lattice Quantum Electrodynamics is a complex quantum field theory with dynamical gauge and matter fields and it has similarities with Quantum Chromodynamics, in particular…
Towards determining the (2+1)-dimensional Quantum Electrodynamics running coupling with Monte Carlo and quantum computing methods
Arianna Crippa, Simone Romiti, Lena Funcke +4
In this paper, we examine a compact lattice gauge theory in dimensions and present a strategy for studying the running coupling and extracting the non-perturbative $…
First-Order Phase Transition of the Schwinger Model with a Quantum Computer
Takis Angelides, Pranay Naredi, Arianna Crippa +4
We explore the first-order phase transition in the lattice Schwinger model in the presence of a topological -term by means of the variational quantum eigensolver (VQE). Using tw…
