Quantum correlations and energy currents across finite harmonic chains
Antonio A. Valido, Antonia Ruiz, Daniel Alonso
We present a study that addresses both the stationary properties of the energy current and quantum correlations in a three-mode chain subjected to Ohmic and super-Ohmic dissipa- ti…
Tuning heat transport in trapped-ion chains across a structural phase transition
Antonia Ruiz, Daniel Alonso, Martin B. Plenio +1
We explore heat transport across an ion Coulomb crystal beyond the harmonic regime by tuning it across the structural phase transition between the linear and zigzag configurations.…
Jaynes-Cummings model in a finite Kerr medium
A. Martín Ruiz, Alejandro Frank, L. F. Urrutia
We introduce a spin model which exhibits the main properties of a Kerr medium to describe an intensity dependent coupling between a two-level atom and the radiation field. We selec…
Quantum quasiresonances in grazing incident angle atom-surface collisions
Antonia Ruiz, Jose P. Palao, Eric J. Heller
The momentum transfer between the normal components to an index direction in the collision of an atom with a periodic surface is investigated. For fast atoms with grazing angle of…
Escape of photons from two fixed extreme Reissner-Nordström black holes
Daniel Alonso, Antonia Ruiz, Manuel Sánchez-Hernández
We study the scattering of light (null geodesics) by two fixed extreme Reissner-Nordström black holes, in which the gravitational attraction of their masses is exactly balanced wit…
Quasiresonance
Antonia Ruiz, Eric J. Heller
The concept of quasiresonance was introduced in connection with inelastic collisions between one atom and a vibro-rotationally excited diatomic molecule. In its original form, the…
