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…
Quantum phases of dipolar bosons in one-dimensional optical lattices
Rebecca Kraus, Titas Chanda, Jakub Zakrzewski +1
We theoretically analyze the phase diagram of a quantum gas of bosons that interact via repulsive dipolar interactions. The bosons are tightly confined by an optical lattice in a q…
Self-organized topological insulator due to cavity-mediated correlated tunneling
Titas Chanda, Rebecca Kraus, Giovanna Morigi +1
Topological materials have potential applications for quantum technologies. Non-interacting topological materials, such as e.g., topological insulators and superconductors, are cla…
Staggered superfluid phases of dipolar bosons in two-dimensional square lattices
Kuldeep Suthar, Rebecca Kraus, Hrushikesh Sable +3
We study the quantum ground state of ultracold bosons in a two-dimensional square lattice. The bosons interact via the repulsive dipolar interactions and s-wave scattering. The dyn…
Superfluid phases induced by the dipolar interactions
Rebecca Kraus, Krzysztof Biedroń, Jakub Zakrzewski +1
We determine the quantum ground state of dipolar bosons in a quasi-one-dimensional optical lattice and interacting via -wave scattering. The Hamiltonian is an extended Bose-Hubb…
Mean-field phase diagram of ultracold atomic gases in cavity quantum electrodynamics
Lukas Himbert, Cecilia Cormick, Rebecca Kraus +2
We investigate the mean-field phase diagram of the Bose-Hubbard model with infinite-range interactions in two dimensions. This model describes ultracold bosonic atoms confined by a…
Localization transition in presence of cavity backaction
Katharina Rojan, Rebecca Kraus, Thomás Fogarty +3
We study the localization transition of an atom confined by an external optical lattice in a high-finesse cavity. The atom-cavity coupling yields an effective secondary lattice pot…
