Area of Science:

  • Statistical Mechanics
  • Computational Physics
  • Nonlinear Dynamics

Background:

  • Granular gases exhibit complex nonequilibrium dynamics under gravity.
  • Rotor dynamics can be influenced by friction and surrounding media.
  • Probing granular gas properties requires suitable experimental or computational tools.

Purpose of the Study:

  • To investigate the dynamics of a rotor interacting with a granular gas.
  • To establish the rotor's utility as a nonequilibrium probe for granular systems.
  • To derive and validate a theoretical mapping between rotor and gas properties.

Main Methods:

  • Numerical investigation using molecular dynamics (MD) simulations.
  • Analytical derivation of a mapping between velocity distribution functions.
  • Simulations performed with a rotor under viscous or dry friction in a granular gas.

Main Results:

  • A one-to-one theoretical map was derived between the granular gas's velocity distribution function (VDF) and the rotor's angular distribution function.
  • MD simulations confirmed the accuracy of this derived map.
  • The rotor successfully inferred local VDF of the granular gas and vice versa.

Conclusions:

  • The rotor serves as an effective nonequilibrium probe for granular gases.
  • The derived mapping provides a reliable method for interchanging information between rotor and gas dynamics.
  • This study validates a novel approach for characterizing complex granular systems.
