QCDF90: Lattice QCD with Fortran 90
I. Dasgupta, A. R. Levi, V. Lubicz +1
We have used Fortran 90 to implement lattice QCD. We have designed a set of machine independent modules that define fields (gauge, fermions, scalars, etc...) and overloaded operato…
Estimating Vacuum Tunneling Rates
Indranil Dasgupta
We show that in Euclidean field theories that have bounce solutions, the bounce with the least action is the global minimum of the action in an open space of field configurations.…
Binary String Dynamics
Indranil Dasgupta, Ryan Rohm
In this paper we investigate the dynamical properties of binary cosmic strings. We find extrinsic curvature dependence of the string action and show that kinks on binary strings ar…
The Taming of QCD by Fortran 90
I. Dasgupta, A. R. Levi, V. Lubicz +1
We implement lattice QCD using the Fortran 90 language. We have designed machine independent modules that define fields (gauge, fermions, scalars, etc...) and have defined overload…
Vacuum Instability in Low-Energy Supersymmetry Breaking Models
Indranil Dasgupta, Bogdan A. Dobrescu, Lisa Randall
We show that for the simplest models of gauge mediated supersymmetry breaking, including all existing models, the true vacuum will not preserve QCD if it communicates supersymmetry…
QCDF90: A set of Fortran 90 modules for a high-level, efficient implementation of QCD simulations
I. Dasgupta, A. R. Levi, V. Lubicz +1
We present a complete set of Fortran 90 modules that can be used to write very compact, efficient, and high level QCD programs. The modules define fields (gauge, fermi, generators,…
