What can we learn from the dynamics of entanglement and quantum discord in the Tavis-Cummings model?
Juliana Restrepo, Boris A. Rodriguez
We revisit the problem of the dynamics of quantum correlations in the exact Tavis-Cummings model. We show that many of the dynamical features of quantum discord attributed to dissi…
Heat Current Characteristics in Nanojunctions with Superconducting Leads
D. Oettinger, R. Chitra, Juliana Restrepo
As a fundamental requisite for thermotronics, controlling heat flow has been a longstanding quest in solid state physics. Recently, there has been a lot of interest in nanoscale hy…
Decoherence induced by an ordered environment
Juliana Restrepo, S. Camalet, R. Chitra
This Letter deals with the time evolution of a qubit weakly coupled to a reservoir which has a symmetry broken state with long range order at finite temperatures. In particular, we…
Effect of a gap on the decoherence of a qubit
Juliana Restrepo, R. Chitra, S. Camalet +1
We revisit the problem of the decoherence and relaxation of a central spin coupled to a bath of conduction electrons. We consider both metallic and semiconducting baths to study th…
Sudden change of the thermal contact between two quantum systems
J. Restrepo, S. Camalet
In this paper, we address the issue of the stability of the thermal equilibrium of large quantum systems with respect to variations of the thermal contact between them. We study th…
