Spectroscopy of the Dirac oscillator perturbed by a surface delta potential
J. Munárriz, F. DomÃnguez-Adame, R. P. A. Lima
We study theoretically the level shift of the Dirac oscillator perturbed by any sharply peaked potential approaching a surface delta potential. A Green function method is used to o…

Unconventional Floquet topological phases in the SSH lattice
Dunkan MartÃnez, Yuriko Baba, BenjamÃn Santos +4
Topological materials, known for their edge states robust against local perturbations, hold promise for next-generation quantum technologies, but remain scarce in nature and challe…

Out-of-equilibrium dynamical properties of Bose-Einstein condensates in a ramped up weak disorder
Rodrigo P. A. Lima, Milan RadonjiÄ, Axel Pelster
We theoretically study how the superfluid and condensate deformation of a weakly interacting ultracold Bose gas evolve during the ramp-up of an external weak disorder potential. Bo…
