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…
Comment on the claim of physical irrelevance of the topological term
Tanmoy Bhattacharya
We argue that the claim of the absence of charge-conjugation-parity (CP) violating effects due to a topological term in quantum chromodynamics (QCD) is based upon a misunderstandin…
Quantum Data Learning of Topological-to-Ferromagnetic Phase Transitions in the 2+1D Toric Code Loop Gas Model
Shamminuj Aktar, Rishabh Bhardwaj, Andreas Bärtschi +2
Quantum data learning (QDL) provides a framework for extracting physical insights directly from quantum states, bypassing the need for any identification of the classical observabl…
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 $\mat…
