Ilya Sinayskiy, Francesco Petruccione
TL;DR
This paper investigates how two spins interacting with thermal baths evolve over time, providing analytical solutions for their entanglement dynamics under Markovian and Post-Markovian conditions with temperature effects.
Contribution
It offers the first analytical solutions for the reduced density matrix of two spins in both Markovian and Post-Markovian regimes with exponential memory kernel.
Findings

Temperature-dependent behavior of spin-spin entanglement
Comparison of Markovian and Post-Markovian dynamics
Abstract
The dynamics of two spins coupled to bosonic baths at different temperatures is studied. The analytical solution for the reduced density matrix of the system in the Markovian and Post-Markovian case with exponential memory kernel is found. The dynamics and temperature dependence of spin-spin entanglement is analyzed.
