Unitarity of quantum tunneling decay for an analytical exact non-Hermitian resonant-state approach

Gastón García-Calderón, Roberto Romo

By using an exact analytical non-Hermitian formalism involving the full set of resonance (quasinormal) states and complex energy eigenvalues for quantum tunneling decay, we show th…

Effect of the resonance spectra in the propagation of two decaying entangled particles

Gastón García-Calderón, Roberto Romo, Miguel Ángel Terán

An exact analytical solution of the decaying wave function of two identical noninteracting particles, which are entangled by spatial symmetry, is used to analyze the effect of the…

The exponential-nonexponential transition in quantum decay as a phenomenon of interference in time domain of the decaying particle with itself

Gastón García-Calderón, Roberto Romo

By using an exact analytical non-Hermitian approach in terms of resonance (quasinormal) states we express the decaying wave function as the sum of exponential and nonexponential de…

Heisenberg uncertainty relations for the non-Hermitian resonance state solutions to the Schrödinger equation

Gastón García-Calderón, Jorge Villavicencio

Resonance (quasinormal) states correspond to non-Hermitian solutions to the Schrödinger equation obeying outgoing boundary conditions which lead to complex energy eigenvalues and m…

Exact analytical non-Hermitian formulation of the time evolution of decay of one and two identical quantum particles

Gastón García-Calderón

An analytical solution to the time evolution of decay of one and two identical noninteracting particles is presented using the formalism of resonant states. It is shown that the ti…

Nonexponential tunneling decay of a single ultracold atom

Gastón García-Calderón, Roberto Romo

By using an exact analytical approach to the time evolution of decay we investigate the tunneling decay of ultracold single atoms, to discuss the conditions for deviations of the e…
