Title: Weak localization corrections to conductivity and Anderson localization
Organiser: Fysikum, Stockholm University No registration required
The Master's programmes in Physics at Fysikum, SU cover a wide range of topics, spreading from the basic courses in Statistical Physics, Electrodynamics, and Analytical mechanics, to more advanced ones in General Relativity, Cosmology, Quantum Field Theory, Fluid Dynamics, and even recently established Group Theory and Open Quantum Systems.
With many standard courses in classical and quantum fields, the topics of solid state physics, especially in terms of electronic properties of such systems, where many of the lecturers from Fysikum like Eddy Ardonne, Maria Hermanns, Emil Bergholtz, Jonas Ola Oscar Larson, Stefano Bonetti, Andreas Rydh and many others), do their research, are represented mostly by Quantum Field Theory for Condensed Matter.
In this respect, the complimentary topics of quantum transport, interference effects, semiclassical approximation, especially in disordered quantum solid-state systems might be of particular interest for Master students at Fysikum. Quantum localization corrections to the Drude conductivity in generic solid state physics and Anderson localization, emerging out of their divergence, gives a simple, though remarkable example of single-particle quantum phenomena where particle-wave duality reveals itself in a macroscopic quantum phenomenon of the localization of excitations in disordered conducting media.
Applicability of this inteference-based phenomenon to various quantum wave systems, spreading from electrons and spins to sound waves and light excitations, makes it useful for other topics and courses in the programme.
