Control variates for lattice field theory
Tanmoy Bhattacharya, Scott Lawrence, Jun-Sik Yoo
In most lattice field theories, correlators are plagued by a signal-to-noise problem of exponential difficulty in the time separation. We propose a method for improving the signal-…
Instantons, analytic continuation, and -symmetric field theory
Scott Lawrence, Christian Peterson, Paul Romatschke +1
Ordinary Hermitian theory is known to exist in dimensions when . For negative values of the coupling, it has been suggested that a physical meaningful definition…
Deep Learning of Fermion Sign Fluctuations
Scott Lawrence, Yukari Yamauchi
We describe a procedure for alleviating the fermion sign problem in which phase fluctuations are explicitly subtracted from the Boltzmann factor. Several ansätze for fluctuations a…
Semidefinite Programs at Finite Fermion Density
Scott Lawrence
Semidefinite programs can be constructed to provide a non-perturbative view of the zero-temperature behavior of quantum systems. This paper examines the properties of these semidef…
On the Gravitational Wave to Matter Coupling of Superfluid Fermi Gases Near Unitarity
Scott Lawrence, Paul Romatschke
It is well known that gravitational waves distort equilibrium matter globally, making them amenable to detection with laser interferometers. Less well known is the fact that gravit…
Lattice Scalar Field Theory At Complex Coupling
Scott Lawrence, Hyunwoo Oh, Yukari Yamauchi
Lattice scalar field theories encounter a sign problem when the coupling constant is complex. This is a close cousin of the real-time sign problems that afflict the lattice Schwing…
