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…
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…
Monomer-dimer tensor-network basis for qubit-regularized lattice gauge theories
Shailesh Chandrasekharan, Rui Xian Siew, Tanmoy Bhattacharya
Traditional lattice gauge theories (LGTs) can be formulated using an orthonormal basis constructed from the irreducible representations (irreps) of the $\ma…
Transverse Field -Matrix Spin Chains
Rui Xian Siew, Shailesh Chandrasekharan, Ribhu K. Kaul
We introduce a simple lattice spin model that is written in terms of the well-known four-dimensional -matrix representation of the Clifford algebra. The local spins with a four…
