The anisotropic Harper-Hofstadter-Mott model: competition between condensation and magnetic fields
Dario Hügel, Hugo U. R. Strand, Philipp Werner +1
We derive the reciprocal cluster mean-field method to study the strongly-interacting bosonic Harper-Hofstadter-Mott model. The system exhibits a rich phase diagram featuring band i…

Bosonic self-energy functional theory
Dario Hügel, Philipp Werner, Lode Pollet +1
We derive the self-energy functional theory for bosonic lattice systems with broken symmetry by parametrizing the bosonic Baym-Kadanoff effective action in terms of one- and…
