On exact identity between thermodynamic and informatic entropies in a unitary model of friction
Lajos Diósi, Tova Feldmann, Ronnie Kosloff
Abstract
An elementary collision model of a molecular reservoir is considered upon which an external field is applied and the work is dissipated into heat. To realize macroscopic irreversibility at the microscopic level, we introduce a ``graceful'' irreversible map which randomly mixes the identities of the molecules. This map is expected to generate informatic entropy exactly equal to the independently calculable irreversible thermodynamic entropy.
