Surmounting the sign problem in non-relativistic calculations: a case study with mass-imbalanced fermions
Lukas Rammelmüller, William J. Porter, Joaquín E. Drut +1
The calculation of the ground state and thermodynamics of mass-imbalanced Fermi systems is a challenging many-body problem. Even in one spatial dimension, analytic solutions are li…

Evolution from few- to many-body physics in one-dimensional Fermi systems: One- and two-body density matrices, and particle-partition entanglement
Lukas Rammelmüller, William J. Porter, Jens Braun +1
We study the evolution from few- to many-body physics of fermionic systems in one spatial dimension with attractive pairwise interactions. We determine the detailed form of the mom…
