چکیده

With a few notable exceptions, the interaction between the community of mathematicians who work in special functions, in particular, those that are in the area of q-series and basic Hypergeometric functions and the physics community has so far been minimal. In this review article, we will describe some developments in one area in physics, namely the Theory of Random Matrix Ensembles, where a q-generalization has been proposed to be relevant for multifractal states near a critical regime. The term multifractal states refers to the novel fractal characteristics of the quantum mechanical wave functions of a disordered electronic conductor. It is well known in the physics literature that depending on the strength of the disorder, a quantum conductor may undergo a phase-transition from a metallic state which describes a good conductor to those of an insulating state where the (static) conductivity in a finite sample is very small. In a region near the transition such multifractal wave functions are observed at least in numerical experiments.

Multifractal dimensions for all moments for certain critical random-matrix ensembles in the strong multifractality regime.

We construct perturbation series for the qth moment of eigenfunctions of various critical random-matrix ensembles in the strong multifractality regime close to localization. Contrary to previous investigations, our results are valid in the region q<1/2. Our findings allow one to verify, at first leading orders in the strong multifractality limit, the symmetry relation for anomalous fractal dime...

Family of generalized random matrix ensembles.

Using the generalized maximum entropy principle based on the nonextensive q entropy, a family of random matrix ensembles is generated. This family unifies previous extensions of random matrix theory (RMT) and gives rise to an orthogonal invariant stable Lévy ensemble with new statistical properties. Some of them are analytically derived.

Non-extensive Random Matrix Theory - A Bridge Connecting Chaotic and Regular Dynamics

We consider a possible generalization of the random matrix theory, which involves the maximization of Tsallis’ q-parametrized entropy. We discuss the dependence of the spacing distribution on q using a nonextensive generalization of Wigner’s surmises for ensembles belonging to the orthogonal, unitary and symplectic symmetry universal classes. PACS numbers: 03.65.-w, 05.45.Mt, 05.30.Ch

On the similarity between Nakagami-m Fading distribution and the Gaussian ensembles of random matrix theory

We report the similarity between the Nakagami-m fading distribution and the three Gaussian ensembles of random matrix theory. We provide a brief review of random matrix theory and wireless fading. We show that the Nakagami-m distribution serves as mapping between the three ensembles. The statistics of the wireless fading amplitude, as modeled by Nakagami-m distribution, provide a rare example o...
