One-Dimensional Quench Dynamics in an Optical Lattice: sine-Gordon and Bose-Hubbard Descriptions
Subhrajyoti Roy, Rhombik Roy, Andrea Trombettoni +2
We investigate the dynamics of one-dimensional interacting bosons in an optical lattice after a sudden quench in the Bose-Hubbard (BH) and sine-Gordon (SG) regimes. While in higher…
Diminished quantum depletion and correlated droplets in one-dimensional dipolar Bose gas
B. Tüzemen, M. Marciniak, K. Pawłowski
We investigate the formation of self-bound states in a one-dimensional dipolar Bose gas under the influence of both strong short-range repulsive and strong non-local attractive int…
Properties of a trapped multiple-species bosonic mixture at the infinite-particle-number limit: A solvable model
O. E. Alon, L. S. Cederbaum
We investigate a trapped mixture of Bose-Einstein condensates consisting of a multiple number of P species using an exactly-solvable many-body model, the -species harmonic-inter…
Vortices in the Many-Body Excited States of Interacting Bosons in Two Dimension
Mateusz Ślusarczyk, Krzysztof Pawłowski
Quantum vortices play an important role in the physics of two-dimensional quantum many-body systems, though they usually are understood in the single-particle framework like the me…
Coherence of a non-equilibrium polariton condensate across the interaction-mediated phase transition
P. Comaron, E. Estrecho, M. Wurdack +9
The emergence of spatial coherence in a confined two-dimensional Bose gas of exciton-polaritons with tuneable interactions offers a unique opportunity to explore the role of intera…
Transverse Quantum Superfluids
Anatoly Kuklov, Lode Pollet, Nikolay Prokof'ev +1
Even when ideal solids are insulating, their states with crystallographic defects may have superfluid properties. It became clear recently that edge dislocations in He featurin…
