Open harmonic chain without secular approximation
Melika Babakan, Fabio Benatti, Laleh Memarzadeh
We study particle and energy transport in an open quantum system consisting of a three harmonic oscillator chain coupled to thermal baths at different temperatures placed at the en…

An open harmonic chain: Exact vs global and local reduced dynamics
Melika Babakan, Fabio Benatti, Laleh Memarzadeh
In the following, we study the dissipative time-evolution of a quantum chain consisting of three coupled harmonic oscillators, the first and third of which weakly interact quadrati…

Entanglement degradation under local dissipative Landau-Zener noise
Melika Babakan, Arman Kashef, Laleh Memarzadeh
We study entanglement degradation when noise on one share of an entangled pair is described by the dissipative Landau-Zener model. We show that spin-coupling direction to the envir…
