Towards non-Hermitian quantum statistical thermodynamics
Natália Bebiano, João da Providência, João P. da Providência
Non-Hermitian Hamiltonians possessing a discrete real spectrum motivated a remarkable research activity in quantum physics and new insights have emerged. In this paper we formulate…
Fermionic model with a non-Hermitian Hamiltonian
Natália Bebiano, João da Providência, Seiya Nishiyama +1
This paper deals with the mathematical spectral analysis and physical interpretation of a fermionic system described by a non-Hermitian Hamiltonian possessing real eigenvalues. A s…
Non self-adjoint operators with real spectra and extensions of quantum mechanics
N. Bebiano, J. da Providência
In this article, we review the general quantum mechanical setting associated to a non self-adjoint Hamiltonian with real spectrum. Spectral properties of the Hamiltonian of a simpl…
Relativistic particle in a box: Klein-Gordon vs Dirac Equations
Pedro Alberto, Saurya Das, Elias C. Vagenas
The problem of a particle in a box is probably the simplest problem in quantum mechanics which allows for significant insight into the nature of quantum systems and thus is a corne…
Quantum Dynamics in Noisy Backgrounds: from sampling to dissipation and fluctuations
O. Oliveira, W. de Paula, T. Frederico +1
We investigate the dynamics of a quantum system coupled linearly to Gaussian white noise using functional methods. By performing the integration over the noisy field in the evoluti…
General spin and pseudospin symmetries of the Dirac equation
P. Alberto, M. Malheiro, T. Frederico +1
In the 70's Smith and Tassie, and Bell and Ruegg independently found SU(2) symmetries of the Dirac equation with scalar and vector potentials. These symmetries, known as pseudospin…
