Boundary Condition dependent Universality Classes on a Hyperbolic Lattice
Pallabi Dey, Debasish Banerjee, Arnab Kundu +1
We study the ferromagnetic Ising model on finite hyperbolic tessellations of Euclidean AdS with open and wired boundary conditions. Because a finite fraction of spins remains a…
Investigating Interacting Fermionic Models with Locality-Preserving Qubit Encodings
Ashutosh P. Tripathi, Debasish Banerjee, Sandip Maiti +1
We investigate the utility of the locality-preserving Derby-Klassen (DK) fermion-to-qubit mapping [arXiv:2003.06939] for variational quantum simulation of two-dimensional - a…
Spectral Fingerprints of Gauge Theories on a Quantum Computer
Graham Van Goffrier, Debasish Banerjee, Bipasha Chakraborty +1
Maximally mixed state spectral sampling is an unbiased quantum algorithm that allows for extraction of a finite-resolution spectral distribution from a Hamiltonian over potentially…
Symmetric Mass Generation via Multicriticality in a 3D Lattice Gross-Neveu Model
Sandip Maiti, Debasish Banerjee, Shailesh Chandrasekharan +1
We investigate a three-dimensional lattice model of two flavors of massless staggered fermions coupled through two independent four-fermion interactions, and . Using lar…
Interplay of Gauss Law and the fermion sign problem in quantum link models with dynamical matter
Pallabi Dey, Debasish Banerjee, Emilie Huffman
Quantum Link Models with dynamical matter coupled to spin- gauge fields in and can potentially give rise to the Coulomb phase expected in qua…
Phase diagram of a lattice fermion model with symmetric mass generation
Sandip Maiti, Debasish Banerjee, Shailesh Chandrasekharan +1
We study the phase structure of a model containing two flavors of massless staggered fermions interacting through two independent four-fermion couplings, UI and UB, formulated on a…
Bosonic vs. Fermionic Matter in Quantum Simulations of D Gauge Theories
N. S. Srivatsa, Jesse J. Osborne, Debasish Banerjee +1
Quantum link models extend lattice gauge theories beyond the traditional Wilson formulation and present promising candidates for both digital and analog quantum simulations. Fermio…
Cluster-Algorithm-Amenable Models of Gauge Fields and Matter
Emilie Huffman
Typical fermion algorithms require the computation (or sampling) of the fermion determinant. We focus instead on cluster algorithms which do not involve the determinant and involve…
An Improved Single-Plaquette Gauge Action
Debasish Banerjee, Michael Bögli, Kieran Holland +4
We describe and test a nonperturbatively improved single-plaquette lattice action for 4-d SU(2) and SU(3) pure gauge theory, which suppresses large fluctuations of the plaquette, w…
Interfaces, Strings, and a Soft Mode in the Square Lattice Quantum Dimer Model
D. Banerjee, M. Bögli, C. P. Hofmann +3
The quantum dimer model on the square lattice is equivalent to a gauge theory. Quantum Monte Carlo calculations reveal that, for values of the Rokhsar-Kivelson (RK) coupling…
Real-Time Simulation of Large Open Quantum Spin Systems driven by Measurements
D. Banerjee, F. -J. Jiang, M. Kon +1
We consider a large quantum system with spins whose dynamics is driven entirely by measurements of the total spin of spin pairs. This gives rise to a dissipative coup…
Crystalline Confinement
D. Banerjee, P. Widmer, F. -J. Jiang +1
We show that exotic phases arise in generalized lattice gauge theories known as quantum link models in which classical gauge fields are replaced by quantum operators. While these q…
Atomic Quantum Simulation of U(N) and SU(N) Non-Abelian Lattice Gauge Theories
D. Banerjee, M. Bögli, M. Dalmonte +4
Using ultracold alkaline-earth atoms in optical lattices, we construct a quantum simulator for U(N) and SU(N) lattice gauge theories with fermionic matter based on quantum link mod…
Atomic Quantum Simulation of Dynamical Gauge Fields coupled to Fermionic Matter: From String Breaking to Evolution after a Quench
D. Banerjee, M. Dalmonte, M. Müller +4
Using a Fermi-Bose mixture of ultra-cold atoms in an optical lattice, we construct a quantum simulator for a U(1) gauge theory coupled to fermionic matter. The construction is base…
