Supersymmetric gauge theories on the lattice: Pfaffian phases and the Neuberger 0/0 problem
Dhagash Mehta, Simon Catterall, Richard Galvez +1
Recently a class of supersymmetric gauge theories have been successfully implemented on the lattice. However, there has been an ongoing debate on whether lattice versions of some o…
On the sign problem in 2D lattice super Yang--Mills
Simon Catterall, Richard Galvez, Anosh Joseph +1
In recent years a new class of supersymmetric lattice theories have been proposed which retain one or more exact supersymmetries for non-zero lattice spacing. Recently there has be…
Non-abelian gauged NJL models on the lattice
Simon Catterall, Richard Galvez, Jay Hubisz +2
We use Monte Carlo simulation to probe the phase structure of a SU(2) gauge theory containing Dirac fermion flavors transforming in the fundamental representation of the grou…
Phase transitions detached from stationary points of the energy landscape
Michael Kastner, Dhagash Mehta
The stationary points of the potential energy function V are studied for the ϕ^4 model on a two-dimensional square lattice with nearest-neighbor interactions. On the basis of analy…
Numerical Polynomial Homotopy Continuation Method and String Vacua
Dhagash Mehta
Finding vacua for the four dimensional effective theories for supergravity which descend from flux compactifications and analyzing them according to their stability is one of the c…
Towards Modeling HIV Long Term Behavior
Esteban A. Hernandez-Vargas, Dhagash Mehta, Richard H. Middleton
The precise mechanism that causes HIV infection to progress to AIDS is still unknown. This paper presents a mathematical model which is able to predict the entire trajectory of the…
