Massless fermions in uniform flux background on : Vacuum quantum numbers from single-particle filled modes using lattice regulator
Nikhil Karthik, Rajamani Narayanan, Ray Romero
The quantum numbers of monopoles in in the presence of massless fermions have been analyzed using a uniform flux background in coupled to fermions. An analogous…
Scale-invariance and scale-breaking in parity-invariant three-dimensional QCD
Nikhil Karthik, Rajamani Narayanan
We present a numerical study of three-dimensional two-color QCD with and 12 flavors of massless two-component fermions using parity-preserving improved Wilson-Dirac…
Flavor and topological current correlators in parity-invariant three-dimensional QED
Nikhil Karthik, Rajamani Narayanan
We use lattice regularization to study the flow of the flavor-triplet fermion current central charge from its free field value in the ultraviolet limit to its conformal val…
Scale-invariance of parity-invariant three-dimensional QED
Nikhil Karthik, Rajamani Narayanan
We present numerical evidences using overlap fermions for a scale-invariant behavior of parity-invariant three-dimensional QED with two flavors of massless two-component fermions.…
Phase of the fermion determinant in QED_3 using a gauge invariant lattice regularization
Nikhil Karthik, Rajamani Narayanan
We use canonical formalism to study the fermion determinant in different three dimensional abelian gauge field backgrounds that contain non-zero magnetic and electric flux in order…
The equation of state of two dimensional Yang-Mills theory
Nikhil Karthik, Rajamani Narayanan
We study the pressure, , of SU() gauge theory on a two-dimensional torus as a function of area, . We find a cross-over scale that separates the system on a large circl…
