A simple quantum dot: numerical and variational solutions
Connor Walsh, Ian MacPherson, Davidson Joseph +4
We describe a simple quantum dot that consists of two crossed two-dimensional troughs. As such there is no potential well; nonetheless, this geometry gives rise to a bound state, c…
The tight-binding formulation of the Kronig-Penney model
F. Marsiglio, R. L. Pavelich
We provide a derivation of the tight-binding model that emerges from a full consideration of a particle bound in a periodic one-dimensional array of square well potentials, separat…
Impact of spin-orbit coupling on the Holstein polaron
Zhou Li, L. Covaci, M. Berciu +2
We utilize an exact variational numerical procedure to calculate the ground state properties of a polaron in the presence of a Rashba-like spin orbit interaction. Our results corro…
Impact of a finite cut-off for the optical sum rule in the superconducting state
F. Marsiglio, E. van Heumen, A. B. Kuzmenko
A single band optical sum rule derived by Kubo can reveal a novel kind of superconducting state. It relies, however, on a knowledge of the single band contribution from zero to inf…
