Emergent thermal fluctuations and non-Hermitian phase transitions in open photon condensates
Moritz Janning, Roman Kramer, Michael Turaev +2
We investigate the nonequilibrium dynamics of an open photon Bose-Einstein condensate in a dye-filled microcavity using a Lindblad master-equation approach, treating the condensate…
Expansion dynamics of strongly correlated lattice bosons: A selfconsistent density-matrix approach
Julian Schwingel, Michael Turaev, Johann Kroha +1
We study the spatio-temporal dynamics of interacting bosons on a two-dimensional Hubbard lattice in the strongly interacting regime, taking into account the dynamics of condensate…
Stabilizing open photon condensates by ghost-attractor dynamics
Aya Abouelela, Michael Turaev, Roman Kramer +4
We study the temporal, driven-dissipative dynamics of open photon Bose-Einstein condensates (BEC) in a dye-filled microcavity, taking the condensate amplitude and the noncondensed…
Temporal bistability in the dissipative Dicke-Bose-Hubbard system
Tianyi Wu, Sayak Ray, Johann Kroha
We consider a driven-dissipative system consisting of an atomic Bose-Einstein condensates loaded into a two-dimensional Hubbard lattice and coupled to a single mode of an optical c…
Phases and collective modes of bosons in a triangular lattice at finite temperature: A cluster mean field study
M. Malakar, S. Ray, S. Sinha +1
Motivated by the realization of Bose-Einstein condensates (BEC) in non-cubic lattices, in this work we study the phases and collective excitation of bosons with nearest neighbor in…
Chaos induced breakdown of Bose-Hubbard modeling
Sayak Ray, Doron Cohen, Amichay Vardi
We show that the Bose-Hubbard approximation fails due to the emergence of chaos, even when excited modes are far detuned and the standard validity condition is satisfied. This is f…
