Prefect Klein tunneling in anisotropic graphene-like photonic lattices
Omri Bahat-Treidel, Or Peleg, Mark Grobman +3
We study the scattering of waves off a potential step in deformed honeycomb lattices. For small deformations below a critical value, perfect Klein tunneling is obtained. This means…
Dark stationary matter-waves via parity-selective evaporation in a Tonks-Girardeau gas
H. Buljan, O. Manela, R. Pezer +2
We propose a scheme for observing dark stationary waves in a Tonks-Girardeau (TG) gas. The scheme is based on parity-selective dynamical "evaporation" of the gas via a time-depende…
Incoherent matter-wave solitons
H. Buljan, M. Segev, A. Vardi
The dynamics of matter-wave solitons in Bose-Einstein condensates (BEC) is considerably affected by the presence of a surrounding thermal cloud and by condensate depletion during i…
Incoherent matter-wave solitons: Mutual self-trapping of a Bose-Einstein condensate and its surrounding thermal cloud
H. Buljan, M. Segev, A. Vardi
We show that a Bose-Einstein condensate and a portion of its surrounding thermal cloud can exhibit mutual self-trapping, supported by the attractive particle interactions, and not…
