Resistivity of the two-dimensional Bose-Hubbard model at weak coupling

Quantum Gases 2023-09-20 v1

Abstract

We calculate the weak-coupling resistivity of the two-dimensional Bose Hubbard model, comparing with the more familiar fermionic case. At high temperature the resistivity is linear in TT, while in the low temperature normal state it is exponentially suppressed. We explore the density dependence and calculate the momentum relaxation rate.
