Probing the Region of Massless Quarks in Quenched Lattice QCD using Wilson Fermions
Robert G. Edwards, Urs M. Heller, Rajamani Narayanan +1
We study the spectrum of with being the Wilson-Dirac operator on the lattice with bare mass equal to . The background gauge fields are generated using th…
A new method to measure the chiral condensate in lattice QCD using Wilson fermions
Khalil M. Bitar, Urs M. Heller, Rajamani Narayanan
Parity and flavor symmetry is not broken in QCD. Using this fact, we propose a new method to measure the chiral condensate in lattice QCD using Wilson fermions with an operator tha…
The Overlap Formalism and Topological Susceptibility on the Lattice
Rajamani Narayanan, Robert L. Singleton
Recent lattice measurements of the topological susceptibility of SU(2) gauge theory using improved cooling and inverse-blocking are in disagreement. We use the overlap method, whic…
Chiral Gauge Theories in the Overlap Formalism
Rajamani Narayanan
The overlap formula for the chiral determinant is presented and the realization of gauge anomalies and gauge field toplogy in this context is discussed. The ability of the overlap…
Monte Carlo evaluation of a fermion number violating observable in 2D
Yoshio Kikukawa, Rajamani Narayanan, Herbert Neuberger
We describe in some detail a computer evaluation of a 't Hooft vertex in a two dimensional model using the overlap. The computer result agrees with the known exact continuum value,…
Parity Invariant Lattice Regularization of Three-Dimensional Gauge-Fermion System
Rajamani Narayanan, Jun Nishimura
In three dimensions, the effective action for the gauge field induced by integrating out a massless Dirac fermion is known to give either a parity-invariant or a parity-violating r…
