The effects of boundary conditions on Rindler's spectral anomaly
M. A. Estévez, E. SadurnÃ
Rindler's metric is an interesting way to incorporate a set of uniformly accelerated observers into space-time coordinates; this is consistent with special and general relativity.…

Exact solvability of the Gross-Pitaevskii equation for bound states subjected to general potentials
M. Mirón, E. SadurnÃ
In this paper we present the analytic solution to the problem of bound states of the Gross-Pitaevskii (GP) equation in 1D and its properties, in the presence of external potentials…

An exactly solvable tight-binding billiard in graphene
D. Condado, E. SadurnÃ
A triangular graphenic billiard is defined as a planar carbon polymer in the Hückeloid approximation of band electrons. It is shown that the equilateral triangle of arbitrary…
