Unifying topological phase transitions in noninteracting, interacting, and periodically driven systems
Paolo Molignini, R. Chitra, Wei Chen
Topological phase transitions track changes in topological properties of a system and occur in real materials as well as quantum engineered systems, all of which differ greatly in…
MCTDH-X: The multiconfigurational time-dependent Hartree method for indistinguishable particles software
Rui Lin, Paolo Molignini, Luca Papariello +6
We introduce and describe the multiconfigurational time-depenent Hartree for indistinguishable particles (MCTDH-X) software. This powerful tool allows the investigation of ground s…
Pathway to chaos through hierarchical superfluidity in a cavity-BEC system
Rui Lin, Paolo Molignini, Axel U. J. Lode +1
We explore the role of atomic correlations in a harmonically trapped Bose-Einstein condensate coupled to a dissipative cavity, where both the atoms and the cavity are blue detuned…
Generating quantum multi-criticality in topological insulators by periodic driving
Paolo Molignini, Wei Chen, R. Chitra
We demonstrate that the prototypical two-dimensional Chern insulator hosts exotic quantum multi-criticality in the presence of an appropriate periodic driving: a linear Dirac-like…
Superfluid--Mott insulator transition of ultracold superradiant bosons in a cavity
Rui Lin, Luca Papariello, Paolo Molignini +2
We investigate harmonically-trapped, laser-pumped bosons with infinite-range interactions induced by a dissipative high-finesse red-detuned optical cavity with numerical and analyt…
