Equilibration and nonclassicality of a double-well potential

Area of Science:

• Quantum physics
• Atomic physics
• Condensed matter physics

Background:

• Double-well systems with bosonic atoms are ideal for simulating thermalization and equilibration phenomena.
• Understanding these processes is crucial for quantum simulations and statistical mechanics.

Purpose of the Study:

• To conduct an exhaustive analysis of the dynamics and steady-state properties of a double-well system coupled to thermal reservoirs.
• To investigate the conditions under which thermalization occurs.
• To explore nonclassical features, energy fluxes, and finite-time thermodynamics.

Main Methods:

• Simulating a double-well system loaded with bosonic atoms.
• Analyzing system dynamics and steady-state properties.
• Coupling the system to different temperature reservoirs.
• Examining nonclassical features and energy transfer.

Main Results:

• Thermalization in the double-well system was found to occur only 'accidentally'.
• The study identified specific nonclassical features and energy fluxes.
• Finite-time thermodynamics were explored in relation to inter-well correlations.

Conclusions:

• The accidental nature of thermalization highlights unique quantum behaviors in such systems.
• The findings contribute to understanding nonclassical correlations and energy dynamics in quantum simulations.
• This research provides insights into the fundamental processes of thermalization and equilibration in quantum systems.
