Espectro de energía real de un Hamiltoniano p-pseudo hermitiano: caso Oscilador Armónico Bidimensional
(Universidad Nacional del CallaoPE, 2014)
En el presente trabajo se postula un hamiltoniano bidimensional no hermitiano, rasgo no característico con la mecánica cuántica convencional. En principio se demostrará que tal hamiltoniano posee simetría paridad, también ...

Contribuições em modelos de regressão com erro de medida multiplicativo
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2016-02-04)
In regression models in which a covariate is measured with error, it is common
to use structures that correlate the observed covariate with the true non-observed
covariate. Such structures are usually additive or ...
Symmetric quadratic Hamiltonians with pseudo-Hermitian matrix representation
(Academic Press Inc Elsevier Science, 2016-06)
We prove that any symmetric Hamiltonian that is a quadratic function of the coordinates and momenta has a pseudo-Hermitian adjoint or regular matrix representation. The eigenvalues of the latter matrix are the natural ...
Squeezed states, generalized Hermite polynomials and pseudo-diffusion equation
(1992-11-01)
We show that the wavefunctions 〈pq; λ|n〈, of the harmonic oscillator in the squeezed state representation, have the generalized Hermite polynomials as their natural orthogonal polynomials. These wavefunctions lead to ...

Comment on "spontaneous breaking of permutation symmetry in pseudo-Hermitian quantum mechanics"
(American Physical Society, 2017-10)
Li and Miao [Phys. Rev. A 85, 042110 (2012)PLRAAN1050-294710.1103/PhysRevA.85.042110] proposed a non-Hermitian Hamiltonian that is neither Hermitian nor PT symmetric but exhibits real eigenvalues for some values of the ...
Unitarity of the time-evolution and observability of non-Hermitian Hamiltonians for time-dependent Dyson maps
(Iop Publishing Ltd, 2020-06-01)
We present an strategy for the derivation of a time-dependent Dyson map which ensures simultaneously the unitarity of the time evolution and the observability of the whole time-dependent non-Hermitian Hamiltonian or parts ...
Squeezed states from a quantum deformed oscillator Hamiltonian
(Elsevier Science, 2016-03)
The spectrum and the time evolution of a system, which is modeled by a non-hermitian quantum deformed oscillator Hamiltonian, is analyzed. The proposed Hamiltonian is constructed from a non-standard realization of the ...
