Heat conduction in nonlinear lattices is governed by heat flow through a weak link. Analytical and simulation methods confirm tunneling heat flow determines steady-state thermal transport.

Area of Science:

  • Condensed matter physics
  • Nonlinear dynamics
  • Thermal transport phenomena

  • Nonlinear lattice dynamics can exhibit unique thermal transport properties.
  • Interactions between lattice segments significantly influence overall thermal conductivity.

Purpose of the Study:

  • To investigate the heat conduction mechanism in two coupled nonlinear lattices.
  • To determine the role of a weak harmonic link in controlling thermal transport.
  • To develop and validate a theoretical framework for predicting heat flow.

Main Methods:

  • Analytical approach combining self-consistent phonon theory and heat tunneling transport formalism.
