A complex path around the sign problem
Paulo F. Bedaque
We review recent attempts at dealing with the sign problem in Monte Carlo calculations by deforming the region of integration in the path integral from real to complex fields. We d…
Deep Learning Beyond Lefschetz Thimbles
Andrei Alexandru, Paulo Bedaque, Henry Lamm +1
The generalized thimble method to treat field theories with sign problems requires repeatedly solving the computationally-expensive holomorphic flow equations. We present a machine…
Three-body Unitarity in the Finite Volume
M. Mai, M. Döring
The physical interpretation of lattice QCD simulations, performed in a small volume, requires an extrapolation to the infinite volume. A method is proposed to perform such an extra…
Chiral symmetry constraints on resonant amplitudes
Peter C. Bruns, Maxim Mai
We discuss the impact of chiral symmetry constraints on the quark-mass dependence of meson resonance pole positions, which are encoded in non-perturbative parametrizations of meson…
Scattering phaseshift formulas for mesons and baryons in elongated boxes
Frank X. Lee, Andrei Alexandru
We derive Lüscher phaseshift formulas for two-particle states in boxes elongated in one of the dimensions. Such boxes offer a cost-effective way of varying the relative momentum of…
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…
Chiral Extrapolations of the Meson in Lattice QCD Simulations
B. Hu, R. Molina, M. Döring +2
Recent lattice data for meson-meson scattering in -wave and isospin are analyzed using a unitarized model inspired by Chiral Perturbation Theory in the inverse-a…
Tempered transitions between thimbles
Andrei Alexandru, Gokce Basar, Paulo F. Bedaque +1
Quantum field theories with complex actions cannot be investigated using importance sampling due to the sign problem. One possible solution is to use the holomorphic gradient flow,…
