Quantum Vacuum Energy in Graphs and Billiards
L. Kaplan
The vacuum (Casimir) energy in quantum field theory is a problem relevant both to new nanotechnology devices and to dark energy in cosmology. The crucial question is the dependence…
Third quantization
Thomas H. Seligman, Tomaz Prosen
The basic ideas of second quantization and Fock space are extended to density operator states, used in treatments of open many-body systems. This can be done for fermions and boson…
Conformal Mapping and Bound States in Bent Waveguides
Emerson Sadurni, Wolfgang P. Schleich
Is it possible to trap a quantum particle in an open geometry? In this work we deal with the boundary value problem of the stationary Schroedinger (or Helmholtz) equation within a…
The Dirac-Moshinsky oscillator coupled to an external field and its connection to quantum optics
Juan Mauricio Torres, Emerson Sadurni, Thomas H. Seligman
The Dirac-Moshinsky oscillator is an elegant example of an exactly solvable quantum relativistic model that under certain circumstances can be mapped onto the Jaynes-Cummings model…
Two interacting atoms in a cavity: exact solutions, entanglement and decoherence
J. M. Torres, E. Sadurní, T. H. Seligman
We address the problem of two interacting atoms of different species inside a cavity and find the explicit solutions of the corresponding eigenvalues and eigenfunctions using a new…
