Dynamical Evolution of Quantum Correlations and Decoherence in Coupled Oscillators Interacting with a Thermal Reservoir
Somayeh Mehrabankar, Farkhondeh Abbasnezhad, Davood Afshar +1
We investigate the dynamical evolution of quantum discord, entanglement and purity in an open quantum system of two coupled asymmetric harmonic oscillators interacting with a therm…

Opto- and magneto-tunable exceptional degeneracies in non-Hermitian ferromagnet/-wave magnet junctions
Mohammad Alipourzadeh, Davood Afshar, Yaser Hajati
Unconventional -wave magnets (UPMs) with odd-parity spin textures have attracted interest for their zero net magnetization and anisotropic spin-split Fermi surfaces. Here, we ex…

Non-Markovian evolution of a two-level system interacting with a fluctuating classical field via dipole interaction
Samaneh Hesabi, Davood Afshar, Matteo G. A. Paris
We address memory effects in the dynamics of a two-level open quantum system interacting with a classical fluctuating field via dipole interaction. In particular, we study the back…
