We introduce intensive thermodynamic parameters (ITPs) for nonequilibrium systems, which equalize in subsystems. This offers a new tool for studying phase coexistence and measurement challenges in statistical mechanics.

Area of Science:

  • Statistical mechanics
  • Non-equilibrium thermodynamics
  • Condensed matter physics

Background:

  • Steady-state non-equilibrium systems often lack detailed balance, complicating thermodynamic analysis.
  • Traditional thermodynamic parameters are not always applicable to these systems.
  • Additive conserved quantities are common in many physical models.

Purpose of the Study:

  • To introduce a new class of intensive thermodynamic parameters (ITPs) for non-equilibrium systems.
  • To establish a statistical definition of ITPs applicable beyond detailed balance conditions.
  • To demonstrate the utility of ITPs in describing non-equilibrium phenomena like phase coexistence.

Main Methods:

  • Statistical approach to define ITPs conjugated to conserved quantities.

  • Analysis of systems satisfying a general additivity property.
  • Application to models including those with matrix product ansatz.
  • Investigation of ITP equalization in subsystems and upon contact.

    • Main Results:

    • Definition of ITPs that do not require detailed balance.
    • Demonstration that ITPs equalize in subsystems, enabling description of phase coexistence.
    • Exploration of ITP equalization when systems are brought into contact.
    • Proposal of an alternative method for ITP determination via fluctuations.

    Conclusions:

    • The introduced ITPs provide a powerful framework for non-equilibrium statistical mechanics.
    • ITP equalization is a key indicator of equilibrium-like behavior in non-equilibrium systems.
    • Measuring ITPs, though challenging, is crucial for understanding non-equilibrium thermodynamics, with fluctuation measurements offering a viable alternative.
