Quantum transfer-matrix method and thermo-quantum dynamics

Suzuki, Masuo - In: Physica A: Statistical Mechanics and its Applications 321 (2003) 1, pp. 334-339

The quantum transfer-matrix (QTM) method is reviewed and thermo-quantum dynamics is formulated on the basis of the QTM. The free energy of the relevant quantum system (e.g. the one-dimensional Heisenberg model) is expressed only in terms of the maximum eigenvalue λmax of the QTM. Even the...

Anderson localization in a random correlated energy landscape

Russ, Stefanie; Kantelhardt, Jan W.; Bunde, Armin; … - In: Physica A: Statistical Mechanics and its Applications 266 (1999) 1, pp. 492-496

We study the localization of electronic wave functions in the one-dimensional Anderson model with diagonal disorder, where the site energies are long-range correlated. We find different behavior at the band edge and at the band center. Close to the band edge, the correlations lead to a decrease...
