Phys. Rev. E 68, 010201(R) (2003) [3 pages]One-dimensional heat conductivity exponent from a random collision model
We obtain numerically the thermal conductivity of a quasi-one-dimensional classical chain of hard sphere particles as a function of the length of the chain, introducing a fresh model for this problem. The conductivity scales as a power law of the length over two decades, with an exponent very close to the analytical prediction of 1/3. © 2003 The American Physical Society URL:
