-generalization of Stirling approximation and multinominal coefficients
T. Wada, H. Suyari
Stirling approximation of the factorials and multinominal coefficients are generalized based on the one-parameter () deformed functions introduced by Kaniadakis [Phys. Rev. E \t…

The Boltzmann temperature and Lagrange multiplier
T. Wada, A. M. Scarfone
We consider the relation between the Boltzmann temperature and the Lagrange multipliers associated with energy average in the nonextensive thermostatistics. In Tsallis' canonical e…

Interaction Round a Face DMRG method applied to rotational invariant quantum spin chains
Tatsuaki Wada
An interaction-round-a-face density-matrix renormalization-group (IRF-DMRG) method is developed for higher integer spin chain models which are rotational invariant. The expressions…
