Quantum field theory applications for solid state and mesoscopic systems


Dr. Ernestas Žąsinas,
Master studies,
2 semester, spring, 4,5 ECTS credits.


Course unit content:
The basic methods of quantum field theory: field quantization,
properties and use
of Green's function, perturbation theory and Feynman's diagrams.
Applications of quantum field methods to calculate the properties of the interacting
electron gas with the aim to understand how various electron interactions result in such
effects as electr
on mass renormalisation, Coulomb potential screening, plasmons,
superconductivity and magnetism. Solving example problems of mesoscopic systems by
applying the quantum field theory techniques. The charge tunneling and related effects,
charge transport via
the randomly disordered potential are the main topics.
