Saving the Coherent State Path Integral
Yariv Yanay, Erich J. Mueller
By returning to the underlying discrete time formalism, we relate spurious results in coherent state path integral calculations to the high frequency structure of their propagators…

Superfluid Density of Weakly Interacting Bosons on a Lattice
Yariv Yanay, Erich J Mueller
We use a path integral approach to calculate the superfluid density of a Bose lattice gas in the limit where the number of atoms per site is large. Our analytical expressions agree…
