More on the continuum limit of gauge-fixed compact U(1) lattice gauge theory
Asit K. De, Tilak Sinha
We have verified various proposals that were suggested in our last paper concerning the continuum limit of a compact formulation of the lattice U(1) pure gauge theory in 4 dimensio…
Topological charge in 1+1 dimensional lattice theory
Asit K. De, A. Harindranath, Jyotirmoy Maiti +1
We investigate the topological charge in 1+1 dimensional theory on a lattice with Anti Periodic Boundary Condition (APBC) in the spatial direction. We propose a simple order…
Investigations in 1+1 dimensional lattice theory
Asit K. De, A. Harindranath, Jyotirmoy Maiti +1
In this work we perform a detailed numerical analysis of (1+1) dimensional lattice theory. We explore the phase diagram of the theory with two different parameterizations. We…
Investigation of gauge-fixed pure U(1) theory at strong coupling
S. Basak, Asit K. De
We numerically investigate the phase diagram of pure U(1) gauge theory with gauge fixing at strong gauge coupling. The FM-FMD phase transition, which proved useful in defining Abel…
Fermion decoupling and the axial anomaly on the lattice
H. Banerjee, Asit K. De
By an explicit calculation of the continuum limit of the triangle graph amplitude in lattice QED we show that in the axial Ward identity the ABJ anomaly exactly cancels the pseudos…
Lattice Fermions and the Chiral Anomaly
H. Banerjee, Asit K. De
We show in the Wilson model that the contribution of the regular mass term to the four-divergence of the axial vector current in weak coupling perturbation theory is not zero in th…
