Imaginary polarization as a way to surmount the sign problem in ab initio calculations of spin-imbalanced Fermi gases.


From ultracold atoms to quantum chromodynamics, reliable ab initio studies of strongly interacting fermions require numerical methods, typically in some form of quantum Monte Carlo calculation. Unfortunately, (non)relativistic systems at finite density (spin polarization) generally have a sign problem, such that those ab initio calculations are impractical… (More)
