Journal ArticleDOI
Dynamical polarizability, screening and plasmons in one, two and three dimensional massive Dirac systems
TL;DR: The polarization function is used to find the dispersion of the plasmon modes, and electrostatic screening of Coulomb interactions within the random phase approximation, and the oscillating screened potential decays as r -2 and r -3 in two and three dimensions respectively.
Journal ArticleDOI
Plasmon modes of a massive Dirac plasma, and their superlattices
TL;DR: In this article, the collective density oscillations of a collection of charged massive Dirac particles, in one, two, and three dimensions, and their one-dimensional (1D) superlattice were explored.
Journal ArticleDOI
Persistent currents in toroidal dipolar supersolids
TL;DR: In this article, the rotational properties of a dipolar Bose-Einstein condensate trapped in a toroidal geometry were investigated and the ground states in the rotating frame and at fixed angular momenta were observed.
Journal ArticleDOI
Dynamical polarizability, screening, and plasmons in one, two, and three dimensional massive Dirac systems
TL;DR: In this article, the density-density response function of a collection of charged massive Dirac particles was studied in one, two and three dimensions and analytical expressions for the dynamical polarization function were presented.
Journal ArticleDOI
Finite-time interaction quench in a Luttinger liquid
TL;DR: In this paper, the Loschmidt echo was analyzed for a quench in the electron-electron interaction strength, where the change in the interaction strength occurs over a finite time scale.
