Some recent results on contact or point supported potentials
Luis M. Nieto, Manuel Gadella, Juan M. Mateos-Guilarte +2
We introduced some contact potentials that can be written as a linear combination of the Dirac delta and its first derivative, the - interaction. After a simple general pres…
Free energy and entropy for finite temperature quantum field theory under the influence of periodic backgrounds
M. Bordag, J. M. Muñoz-Castañeda, L. Santamaría-Sanz
The basic thermodynamic quantities for a non-interacting scalar field in a periodic potential composed of either a one-dimensional chain of Dirac - functions or a spec…
Revisiting the Casimir Energy with General Boundary Conditions, and applications in 1D Crystals
J. M. Muñoz-Castañeda, M. Bordag, L. Santamaría-Sanz
We obtain new expressions for the Casimir energy between plates that are mimicked by the most general possible boundary conditions allowed by the principles of quantum field theory…
Band spectra of periodic hybrid - structures
M. Gadella, J. M. Mateos Guilarte, J. M. Muñoz-Castañeda +2
We present a detailed study of a generalised one-dimensional Kronig-Penney model using potentials. We analyse the band structure and the density of states in two situ…
Casimir pistons with generalized boundary conditions: a step forward
Guglielmo Fucci, Klaus Kirsten, Jose M. Munoz-Castaneda
In this work we study the Casimir effect for massless scalar fields propagating in a piston geometry of the type where is an interval of the real line and is a…
One-dimensional scattering of fermions on -impurities
J. Mateos Guilarte, Jose M. Munoz-Castaneda, Irina Pirozhenko +1
We study the spectrum of the 1D Dirac Hamiltonian encompassing the bound and scattering states of a fermion distorted by a static background built from -function potentials. We…
