On the entropy for unstable fermionic and bosonic states
(Elsevier, 2014-03)
We focus on the calculation of the entropy for decaying states in non-relativistic quantum mechanics. The starting point is the Friedrichs model in second quantization language. In this model, the Hamiltonian admits a ...
The Gamow-state description of the decay energy spectrum of neutron-unbound 25O
(Elsevier Science, 2018-02)
We show the feasibility of calculating the decay energy spectrum of neutron emitting nuclei within the Gamow-state description of resonances by obtaining the decay energy spectrum of 25O. We model this nucleus as a valence ...
Relativistic RPA for isobaric analogue and Gamow-Teller resonances in closed shell nuclei
(1998-12-17)
We perform a self-consistent relativistic RPA calculation for the isobaric analogue and Gamow-Teller resonances based on relativistic mean field theory results for the ground states of 48Ca, 90Zr and 208Pb. We use the ...
Analyticity of the time dependence of resonance poles: Solving the Friedrichs model with a time-dependent interaction
(American Physical Society, 2012-08)
We extend the standard Friedrichs model with an extra term that includes time-dependent interactions. The time dependence of the poles of the reduced resolvent of the model is explicitly calculated. It is found that these ...
Strength of J π = 1 + Gamow-Teller and isovector spin monopole transitions in double- β -decay triplets
(American Physical Society, 2014-04)
In this work we study systematically the energetics and intensity distributions of Gamow-Teller (GT±) and isovector spin monopole (IVSM±) transitions from the ground states of the pairs (76Ge, 76Se), (82Se, 82Kr), (100Mo, ...
