Názov: Universality in Random Matrix Theory: From energy levels in nuclei to mesoscopic fluctuations in solids

Termín: 27.10.2017, 14:00 hod., F2/272


Abstrakt:
Random Matrix (RM) theory has been enormously successful in describing universal features in a wide variety of physical systems. The Wigner-Dyson RM theory, originally introduced to describe the statistical properties of energy levels of heavy nuclei (dimension ∼ Fermi) also describes the fluctuations in macroscopic chaotic systems (dimension ∼ microns) with no fitting parameters. In this talk I will discuss two one-parameter generalizations of Wigner-Dyson RM theory, both necessary in the context of electron transport in mesoscopic solids.
