Quantum dynamics of Bose-polaron in a -dimensional Bose Einstein condensate
M. Miskeen Khan, H. Terças, J. T. Mendonça +4
We study the quantum motion of an impurity atom immersed in a Bose Einstein condensate in arbitrary dimension. The Bogoliubov excitations of the Bose Einstein condensate act as a b…
Bound-state spectrum of an impurity in a quantum vortex
João E. H. Braz, H. Terças
We consider the problem of finding the bound-state spectrum of an impurity immersed in a weakly interacting two-dimensional Bose-Einstein condensate supporting a single vortex. We…
Turbulence Excitation in Counter-Streaming Paraxial Superfluids of Light
João D. Rodrigues, José T. Mendonça, Hugo Terças
Turbulence in the quantum (superfluid) regime, similarly to its classical counterpart, continues to attract a great deal of scientific inquiry, due to the yet high number of unreso…
Classical Rotons in Cold Atomic Traps
H. Terças, J. T. Mendonça, V. Guerra
We predict the emergence of a roton minimum in the dispersion relation of elementary excitations in cold atomic gases in the presence of diffusive light. In large magneto-topical t…
Rossby waves in rapidly rotating Bose-Einstein condensates
H. Terças, J. P. A. Martins, J. T. Mendonça
We predict and describe a new collective mode in rotating Bose-Einstein condensates, which is very similar to the Rossby waves in geophysics. In the regime of fast rotation, the Co…
