We present a new transport model with internal states applicable to traffic and spintronics. This model reveals a polarization phenomenon controllable by system rates, with findings validated by simulations.

Area of Science:

  • Statistical Mechanics
  • Condensed Matter Physics
  • Transport Phenomena

Background:

  • Driven exclusion processes are fundamental models for systems out of equilibrium.
  • Understanding nonequilibrium steady states is crucial in diverse fields like traffic flow and spintronics.
  • Controlling transport properties via system parameters remains a key challenge.

Purpose of the Study:

  • To introduce a generalized driven exclusion process incorporating internal states.
  • To investigate the control of nonequilibrium steady states through boundary and bulk rates.
  • To discover and analyze novel phenomena like polarization and domain wall dynamics.

Main Methods:

  • Development of a theoretical framework for driven exclusion processes with internal states.
