We demonstrate a method to control energy flow between thermal baths using a diatomic system. By preparing specific atomic states, we can switch the photon flow, offering a new control mechanism.
Area of Science:
- Quantum optics
- Thermodynamics
- Atomic physics
Background:
- Controlling energy flow between thermal reservoirs is crucial for thermodynamics.
- Non-equilibrium steady states are key to understanding energy transport.
- Optical cavities offer a platform for manipulating quantum systems.
Purpose of the Study:
- To propose a controllable system for energy flow between two thermal baths.
- To investigate the role of atomic state symmetry in photon transport.
- To implement a deterministic method for controlling energy flow.
Main Methods:
- Utilizing a simple diatomic system within an optical cavity.
- Driving the system to a non-equilibrium steady state via thermal baths.
- Applying Large Deviation theory to analyze photon flow.
- Employing external driving fields to prepare specific atomic states.
Main Results:
- Photon flow between baths is highly sensitive to the symmetry of atomic states.
- A deterministic scheme for preparing symmetric and antisymmetric states was developed.
- The system acts as an atomic control switch for energy flow.
Conclusions:
- Atomic state symmetry provides a powerful handle for controlling energy flow.
- External driving fields enable deterministic preparation of states for energy flow control.
- This work presents a novel approach to manipulating energy transport in quantum systems.
