Spectroscopy of the Dirac oscillator perturbed by a surface delta potential
J. Munárriz, F. Domínguez-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 Martínez, Yuriko Baba, Benjamín 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 Radonjić, 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…
Uncovering Bound States in the Continuum in InSb nanowire networks
D. Martínez, P. A. Orellana, L. Rosales +5
Bound states in the continuum (BICs) are exotic, localized states even though their energy lies in the continuum spectra. Since its discovery in 1929, the quest to unveil these exo…
Charge migration mechanisms in the DNA at finite temperature revisited; from quasi-ballistic to subdiffusive transport
R. P. A. Lima, A. V. Malyshev
Various charge migration mechanisms in the DNA are studied within the framework of the Peyrard-Bishop-Holstein model which has been widely used to address charge dynamics in this m…
Electron pairing in periodic potentials under an external electric field
Christopher Gaul, Antonio Rodríguez, Rodrigo P. A. Lima +1
We study the semiclassical dynamics of interacting electrons in a biased crystal lattice. A complex dynamical scenario emerges from the interplay between the Coulomb and the extern…
