Adiabatic Process and Chern Numbers | Jun Goryo

29 Jun 2006 | Subject: | Mesoscopic Systems and Quantum Hall Effect; Statistical Mechanics | Abstract: | We study quantum processes with two or more adiabatic parameters. When the parameters are compactified, a derivative of the Hamiltonian gives a first Chern number, hence an integer. This topological formulation is applied to the AC Josephson effect and the spin Hall effect in semiconductors. | Source: | arXiv, cond-mat/0606758 | Services: | Forum | Review | PDF | Favorites |
