Temperature and pressure in nonextensive thermostatistics

Résumé

The definitions of the temperature in the nonextensive statistical thermodynamicsbased on Tsallis entropy are analyzed. A definition of pressure is proposed fornonadditive systems by using a nonadditive effective volume. The thermodynamics ofnonadditive photon gas is discussed on this basis. We show that the Stefan-Boltzmannlaw can be preserved within nonextensive thermodynamics.
