Schwinger-Keldysh on the lattice: a faster algorithm and its application to field theory
Andrei Alexandru, Gokce Basar, Paulo F. Bedaque +1
A new algorithm is developed allowing the Monte Carlo study of a 1 + 1 dimensional theory in real time. The main algorithmic development is to avoid the explicit calculation of the…
Monte Carlo calculations of the finite density Thirring model
Andrei Alexandru, Gokce Basar, Paulo F. Bedaque +2
We present results of the numerical simulation of the two-dimensional Thirring model at finite density and temperature. The severe sign problem is dealt with by deforming the domai…
A study of symmetry breaking in a relativistic Bose gas using the contraction algorithm
Andrei Alexandru, Gokce Basar, Paulo Bedaque +2
A relativistic Bose gas at finite density suffers from a sign problem that makes direct numerical simulations not feasible. One possible solution to the sign problem is to re-expre…
Fast Estimator of jacobians in Monte Carlo Integration on Lefschetz Thimbles
Andrei Alexandru, Gokce Basar, Paulo F. Bedaque +2
A solution to the sign problem is the so-called "Lefschetz thimble approach" where the domain of integration for field variables in the path integral is deformed from the real axis…
Sign problem and Monte Carlo calculations beyond Lefschetz thimbles
Andrei Alexandru, Gokce Basar, Paulo F. Bedaque +2
We point out that Monte Carlo simulations of theories with severe sign problems can be profitably performed over manifolds in complex space different from the one with fixed imagin…
