Zeroth law of thermodynamics and the transformation from nonextensive to extensive framework
Ramandeep S. Johal
Within the nonextensive framework, it is shown that zeroth law of thermodynamics determines not only the mapping between Lagrange multipliers and intensive variables, but also the…
On the correct entropic form for systems with power-law behaviour: the case of dissipative maps
Ramandeep S. Johal, Ugur Tirnakli
Maximum entropy principle does not seem to distinguish between the use of Tsallis and Renyi entropies as either of them may be used to derive similar power-law distributions. In th…
On matrix elements of phase-angular momentum commutator in Hilbert space of arbitrary dimensions
Ramandeep S. Johal
We discuss correspondence between the predictions of quantum theories for rotation angle formulated in infinite and finite dimensional Hilbert spaces, taking as example, the calcul…
Phase shift operator and cyclic evolution in finite dimensional Hilbert space
Ramandeep S. Johal
We address the problem of phase shift operator acting as time evolution operator in Pegg-Barnett formalism. It is argued that standard shift operator is inconsistent with the behav…
An interpretation of Tsallis statistics based on polydispersity
Ramandeep S. Johal
It is argued that polydispersed systems like colloids provide a direct example where Tsallis' statistical distribution is useful for describing the heirarchical nature of the syste…
Generalized bit cumulants for chaotic systems: Numerical results
Renuka Rai, Ramandeep S. Johal
We propose generalized bit cumulants for chaotic systems, within nonextensive thermodynamic approach. In this work, we apply the first and second generalized cumulants to one dimen…
