(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…
Toward Hamiltonian simulations of Maxwell-Chern-Simons theory: constant modes and gauge field truncation
Andrea Bulgarelli, Maria Cristina Diamantini, Nico Dichter +6
Maxwell-Chern-Simons (MCS) theory in dimensions provides a paradigmatic example of a topological gauge theory with both dynamical and topological degrees of freedom. Its Eucl…
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…
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…
