Hall conductivity as a topological invariant
A. Kunold, M. Torres
The object of the present work is to study the quantum Hall effect through its symmetries and topological aspects. We consider the model of an electron moving in a two-dimensional…
A model for the microwave assisted zero resistance states
Manuel Torres, Alejandro Kunold
In this work we present a model for the photoconductivity of a two dimensional electron system (2DES) subjected to a magnetic field. The model includes the microwave and Landau con…
Hofstadter spectrum in electric and magnetic fields
Alejandro Kunold, Manuel Torres
The problem of Bloch electrons in two dimensions subject to magnetic and intense electric fields is investigated. Magnetic translations, electric evolution and energy translation o…
Kubo formula for Floquet states and photoconductivity oscillations in a 2D electron gas
Manuel Torres, Alejandro Kunold
The recent discovery of the microwave induced vanishing resistance states in a two dimensional electron system (2DES) is an unexpected and surprising phenomena. In these experiment…
