Random matrix theory and critical phenomena in quantum spin chains.

We compute critical properties of a general class of quantum spin chains which are quadratic in the Fermi operators and can be solved exactly under certain symmetry constraints related to the classical compact groups U(N),O(N), and Sp(2N). In particular we calculate critical exponents s,ν, and z, corresponding to the energy gap, correlation length, and dynamic exponent, respectively. We also co...

Representation theory and quantum integrability ∗

We describe new constructions of the infinite-dimensional representations of U(g) and Uq(g) for g being gl(N) and sl(N). The application of these constructions to the quantum integrable theories of Toda type is discussed. With the help of these infinitedimensional representations we manage to establish direct connection between group theoretical approach to the quantum integrability and Quantum...

Incompleteness of Representation Theory: Hidden symmetries and Quantum Non-Integrability

When regular regions are discovered in the parameter space of a system, where the parameter might be an external field applied to the Hydrogen atom, it usually indicates the existence of new (approximate) integrals of motion, and consequently quantum numbers [1]. In studies of many–body systems, the large number of degrees of freedom generally precludes one from using methods introduced in simp...

Entanglement in quantum critical phenomena.

Entanglement, one of the most intriguing features of quantum theory and a main resource in quantum information science, is expected to play a crucial role also in the study of quantum phase transitions, where it is responsible for the appearance of long-range correlations. We investigate, through a microscopic calculation, the scaling properties of entanglement in spin chain systems, both near ...

Critical Phenomena in Percolation Theory

In this paper, the critical behavior of the percolation models is reviewed, with emphasis on the scaling laws present and its relationship with other simple models like the Ising magnet. A liitle bit of the history and some examples of its application are given to illustrate the range of phenomena that can be described with such models.
