Inverse Currents in Hamiltonian Coupled Transport.

Area of Science:

• Statistical Mechanics
• Condensed Matter Physics
• Non-equilibrium Thermodynamics

Background:

• Inverse current, where induced current opposes applied force, is a counterintuitive phenomenon.
• Coupled transport of energy and particles in interacting systems is complex.
• Understanding non-equilibrium phenomena is crucial for advanced material science.

Purpose of the Study:

• To explain the occurrence of inverse currents in coupled transport (ICC).
• To investigate the role of self-organization in generating inverse currents.
• To analyze the behavior of a one-dimensional interacting Hamiltonian system under coupled thermodynamic forces.

Main Methods:

• Theoretical analysis of a one-dimensional interacting Hamiltonian system.
• Perturbation of the system's equilibrium state using coupled thermodynamic forces.
• Investigation of coupled transport of energy and particles.

Main Results:

• Demonstrated the occurrence of inverse currents (ICC) in the studied system.
• Identified self-organization as the mechanism behind the inverse current phenomenon.
• Showcased that inverse currents arise from the system's response to coupled thermodynamic forces.

Conclusions:

• Inverse currents in coupled transport are possible in specific non-equilibrium conditions.
• Self-organization plays a key role in generating paradoxical transport phenomena.
• The findings offer new insights into the behavior of interacting systems far from equilibrium.
