Real and Imaginary Part of Conductivity of Strongly Interacting Bosons in Optical Lattices

2019 · Acta Physica Polonica A

We calculate the conductivity of strongly interacting bosons described by the Bose-Hubbard model in a twodimensional lattice in controlled gauge potential acting as a uniform external magnetic field. In such scenario, two types of conductivity …
