A microscopic theory of Anderson localization of electrons in random lattices
Václav Janiš
The existence of Anderson localization, characterized by vanishing diffusion due to strong disorder, has been demonstrated in numerous ways. A systematic approach based on the Ande…

Dynamical Mean-Field Theory of Disordered Electrons: Coherent Potential Approximation and Beyond
Václav Janiš
I review the quantum theory of the electron moving in a random environment. First, the quantum mechanics of individual particles scattered on a random potential is discussed. The q…

Introduction to Mean-Field Theory of Spin Glass Models
Václav Janiš
We discuss the mean-field theory of spin-glass models with frustrated long-range random spin exchange. We analyze the reasons for breakdown of the simple mean-field theory of Sherr…
