Quantum critical behavior of entanglement in lattice bosons with cavity-mediated long-range interactions
Shraddha Sharma, Simon B. Jaeger, Rebecca Kraus +2
We analyze the ground-state entanglement entropy of the extended Bose-Hubbard model with infinite-range interactions. This model describes the low-energy dynamics of ultracold boso…

Bond order via cavity-mediated interactions
Titas Chanda, Rebecca Kraus, Jakub Zakrzewski +1
We numerically study the phase diagram of bosons tightly trapped in the lowest band of an optical lattice and dispersively coupled to a single-mode cavity field. The dynamics is en…
