Variational approach to -body interactions in finite volume
Peng Guo, Michael Döring, Adam P. Szczepaniak
We explore variational approach to the finite-volume -body problem. The general formalism for N non-relativistic spinless particles interacting with periodic pair-wise potential…
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…
Finite-volume spectrum of and systems
Maxim Mai, Michael Doring
The ab-initio understanding of hadronic three-body systems above threshold, such as exotic resonances or the baryon spectrum, requires the mapping of the finite-volume eigenvalue s…
Spin Polarized Non-Relativistic Fermions in 1+1 Dimensions
Andrei Alexandru, Paulo F. Bedaque, Neill C. Warrington
We study by Monte Carlo methods the thermodynamics of a spin polarized gas of non-relativistic fermions in 1+1 dimensions. The main result of this work is that our action suffers n…
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…
Extraction of isoscalar phase-shifts from lattice QCD
Dehua Guo, Andrei Alexandru, Raquel Molina +2
We conduct a two-flavor () lattice QCD calculation of the elastic phase-shifts for pion-pion scattering in the scalar, isoscalar channel (the -meson). The calculation is…
Three-body spectrum in a finite volume: the role of cubic symmetry
M. Döring, H. -W. Hammer, M. Mai +3
The three-particle quantization condition is partially diagonalized in the center-of-mass frame by using cubic symmetry on the lattice. To this end, instead of spherical harmonics,…
