Spectral reconstruction techniques, their shortcomings and relevance to the electric conductivity coefficient
C. Andratschke, B. B. Brandt, E. Garnacho-Velasco +3
Spectral reconstruction is a well studied numerically ill-posed problem which arises due to the relation of the Euclidean correlator to the spectral function via an inhomogeneous F…
Normalizing-flow-based density of states for (1+1)D U(1) lattice gauge theory with a -term
Simran Singh, Lena Funcke
A normalizing-flow-based implementation of the density-of-states approach has recently been used to successfully reconstruct the partition function of (1+1)D scalar lattice field t…
Hamiltonian Lattice QED with One and Two Flavors of Wilson Fermions: Topological Structure and Response
Sriram Bharadwaj, Emil Rosanowski, Simran Singh +5
The quantum simulation of topological phases in (2+1)D quantum electrodynamics with Wilson fermions provides a promising route toward realizing topological phenomena in near-term l…
(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…
A Path to Quantum Simulations of Topological Phases: (2+1)D Quantum Electrodynamics with Wilson Fermions
Sriram Bharadwaj, Emil Rosanowski, Simran Singh +5
Quantum simulation offers a powerful approach to studying quantum field theories, particularly (2+1)D quantum electrodynamics (QED) with Wilson fermions, which hosts a rich lan…
