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…
