Continuum limit of a qubit-regularized SU(3) lattice gauge theory with glueballs
Rui Xian Siew, Shailesh Chandrasekharan, Tanmoy Bhattacharya
We show that a simple qubit-regularized lattice gauge theory (LGT) on a plaquette chain admits a continuum limit with massive glueball excitations, providing a min…
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…
Confined and Deconfined Phases of Qubit Regularized Lattice Gauge Theories
Shailesh Chandrasekharan
We construct simple qubit-regularized Hamiltonian lattice gauge theories formulated in the monomer--dimer--tensor-network (MDTN) basis that are free of sign problems in the pure ga…
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…
Asymptotic-freedom and massive glueballs in a qubit-regularized SU(2) gauge theory
Rui Xian Siew, Shailesh Chandrasekharan, Tanmoy Bhattacharya
We argue that a simple qubit-regularized lattice gauge theory (LGT) on a plaquette chain serves as a pseudo-one-dimensional toy model for Yang-Mills (YM) theory in…
Symmetric mass generation as a multicritical point with enhanced symmetry
Sandip Maiti, Debasish Banerjee, Shailesh Chandrasekharan +1
We explore the phase diagram of a lattice fermion model that exhibits three distinct phases: a massless fermion (MF) phase; a massive fermion phase with spontaneous symmetry breaki…
