Time-Dependent Logarithmic Perturbation Theory for Quantum Dynamics: Formulation and Applications
Juan Carlos del Valle, Paul Bergold, Karolina Kropielnicka
We present a time-dependent extension of logarithmic perturbation theory for nonrelativistic quantum dynamics governed by the Schrödinger equation, in which the logarithm of the wa…
Optimal entanglement generation in GHZ-type states
N. Giovenale, L. Hernandez-Martinez, A. P. Majtey +1
The entanglement production is key for many applications in the realm of quantum information, but so is the identification of processes that allow to create entanglement in a fast…
Underlying non-Hermitian character of the Born rule in open quantum systems
Gastón García-Calderón, Lorea Chaos-Cador
The absolute value squared of the probability amplitude corresponding to the overlap of an initial state with a continuum wave solution to the Schrödinger equation of the problem,…
Time evolution of decay for purely absorptive potentials: The effect of spectral singularities
Gastón García-Calderón, Lorea Chaos-Cador
We consider an analytical approach that involves the complex poles of the propagator to investigate the effect due to the lack of time reversal invariance on the time evolution of…
An exactly soluble model of a shallow double well
R. Muñoz-Vega, E. López-Chávez, E. Salinas-Hernández +2
Shallow one-dimensional double well potentials appear in atomic and molecular physics and other fields. Unlike the "deep" wells of macroscopic quantum coherent systems, shallow dou…
On the possibility of measuring the Unruh effect
Igor Peña, Daniel Sudarsky
There is a persistent state of confusion regarding the nature of the Unruh effect. We will argue that, in contrast to some interpretations thereof, the effect does not represent an…
