Quantum information scrambling in two-dimensional Bose–Hubbard lattices
It is a well-understood fact that the transport of excitations throughout a lattice is intimately
governed by the underlying structures. Hence, it is only natural to recognize that the …

Finite-size scaling analysis of localization transitions in the disordered two-dimensional Bose-Hubbard model within the fluctuation operator expansion method
A Geißler - Physical Review A, 2021 - APS
The disordered Bose-Hubbard model in two dimensions at noninteger filling admits a
superfluid to Bose-glass transition at weak disorder. Less understood are the properties of …
