The effects of boundary conditions on Rindler's spectral anomaly
M. A. Estévez, E. Sadurní
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. Sadurní
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. Sadurní
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 s…
Exact Green's functions for localized irreversible potentials
J. I. Castro--Alatorre, D. Condado, E. Sadurní
We study the quantum-mechanical problem of scattering caused by a localized obstacle that breaks spatial and temporal reversibility. Accordingly, we follow Maxwell's prescription t…
Does an accelerated mirror suffer hindrance from vacuum?
E. Sadurní, M. A. Estévez, J. L. Díaz-Cruz
We study the accelerated motion of mirrors and the photonic Unruh effect. The solutions of Maxwell's equations with appropriate boundary conditions in Rindler coordinates are found…
