The low lying modes of triplet-condensed neutron matter and their effective theory
Paulo F. Bedaque, Amy N. Nicholson
The condensation of neutrons into a 3P2 superfluid phase occurs at densities relevant for the interior of neutron stars. The triplet pairing breaks rotational symmetry spontaneousl…
Elucidating the sign problem through noise distributions
Amy N. Nicholson, Dorota Grabowska, David B. Kaplan
Due to the presence of light pions in the theory, lattice QCD at finite densities suffers from issues with noise in both grand canonical and canonical formulations. We study two di…
Lattice methods for strongly interacting many-body systems
Joaquín E. Drut, Amy N. Nicholson
Lattice field theory methods, usually associated with non-perturbative studies of quantum chromodynamics, are becoming increasingly common in the calculation of ground-state and th…
Sign problems, noise, and chiral symmetry breaking in a QCD-like theory
Dorota Grabowska, David B. Kaplan, Amy N. Nicholson
The Nambu-Jona-Lasinio model reduced to 2+1 dimensions has two different path integral formulations: at finite chemical potential one formulation has a severe sign problem similar…
Lattice Monte Carlo calculations for unitary fermions in a finite box
Michael G. Endres, David B. Kaplan, Jong-Wan Lee +1
We perform lattice Monte Carlo simulations for up to 66 unitary fermions in a finite box using a highly improved lattice action for nonrelativistic spin 1/2 fermions. We obtain a v…
N-body Efimov states from two-particle noise
Amy N. Nicholson
The ground state energies of universal N-body clusters tied to Efimov trimers, for N even, are shown to be encapsulated in the statistical distribution of two particles interacting…
