Quantum Rayleigh problem and thermocoherent Onsager relations

The role of quantum coherence and correlations in heat flow equilibration is investigated by exploring the Rayleigh's dynamical problem to regime following Onsager's approach thermoelectricity. Specifically, we consider a qubit bombarded two-qubit projectiles from side. For arbitrary collision times initial states, develop master equation for sequential collective collisions. By deriving Fokker-Planck out equation, identify version conduction equation. We find that discord entanglement shared between can contribute genuine only when they are associated with so-called heat-exchange coherences. Analogous use principle least dissipation energy, entropy production rate current. Both flows be written form Onsager relations, which predict coherent Peltier Seebeck effects. effects optimized collectivity. Finally, discuss some possible experimental realizations technological applications thermocoherent phenomena different platforms.
