Beyond Thimbles: Sign-Optimized Manifolds for Finite Density
Scott Lawrence
The sign problem of relativistic field theories at finite fermion chemical potential has been approached by deforming the domain of integration into complex field space. We present…
Fermions at Finite Density in (2+1)d with Sign-Optimized Manifolds
Andrei Alexandru, Paulo F. Bedaque, Henry Lamm +2
We present Monte Carlo calculations of the thermodynamics of the (2+1) dimensional Thirring model at finite density. We bypass the sign problem by deforming the domain of integrati…
Finite Density Near Lefschetz Thimbles
Andrei Alexandru, Gokce Basar, Paulo F. Bedaque +2
One strategy for reducing the sign problem in finite-density field theories is to deform the path integral contour from real to complex fields. If the deformed manifold is the appr…
Simulation of Nonequilibrium Dynamics on a Quantum Computer
Henry Lamm, Scott Lawrence
We present a hybrid quantum-classical algorithm for the time evolution of out-of-equilibrium thermal states. The method depends upon classically computing a sparse approximation to…
Finite-Density Monte Carlo Calculations on Sign-Optimized Manifolds
Andrei Alexandru, Paulo Bedaque, Henry Lamm +1
We present a general technique for addressing sign problems that arise in Monte Carlo simulations of field theories. This method deforms the domain of the path integral to a manifo…
