Report

Stabilization of collapse and revival dynamics by a non-Markovian phonon bath

Autor: Carmele, Alexander, Knorr, Andreas, Milde, Frank

Publikováno v: New J. Phys. 15, 105024 (2013)

Semiconductor quantum dots (QDs) have been demonstrated to be versatile candidates to study the fundamentals of light-matter interaction [1-3]. In contrast with atom optics, dissipative processes are induced by the inherent coupling to the environmen

Report

Critical properties of the metal-insulator transition in anisotropic systems

Autor: Milde, Frank, Römer, Rudolf A., Schreiber, Michael, Uski, Ville

We study the three-dimensional Anderson model of localization with anisotropic hopping, i.e., weakly coupled chains and weakly coupled planes. In our extensive numerical study we identify and characterize the metal-insulator transition by means of th

Publikováno v: PRB 61, 6028-6035 (2000)

We study the three-dimensional Anderson model of localization with anisotropic hopping, i.e. weakly coupled chains and weakly coupled planes. In our extensive numerical study we identify and characterize the metal-insulator transition using energy-le

Report

Energy level statistics at the metal-insulator transition in the Anderson model of localization with anisotropic hopping

Autor: Milde, Frank, Römer, Rudolf A.

Publikováno v: Proceedings of PILS'98: Ann. Phys. (Leipzig) 7, 452-456 (1998)

Recently, a metal-insulator transition (MIT) was found in the anisotropic Anderson model of localization by transfer-matrix methods (TMM). This MIT has been also investigated by multifractal analysis (MFA) and the same critical disorders $W_c$ have b

Report

Multifractal analysis of the metal-insulator transition in anisotropic systems

Autor: Milde, Frank, Römer, Rudolf A., Schreiber, Michael

Publikováno v: Phys. Rev. B 55, 9463-9469 (1997)

We study the Anderson model of localization with anisotropic hopping in three dimensions for weakly coupled chains and weakly coupled planes. The eigenstates of the Hamiltonian, as computed by Lanczos diagonalization for systems of sizes up to $48^3$
