Real-time dynamics at finite temperature by DMRG: A path-integral approach
J. Sirker, A. Klümper
We propose a path-integral variant of the DMRG method to calculate real-time correlation functions at arbitrary finite temperatures. To illustrate the method we study the longitudi…

Thermodynamics and Crossover Phenomena in the Correlation Lengths of the One-Dimensional t-J Model
J. Sirker, A. Klümper
We investigate the thermodynamics of the one-dimensional t-J model using transfer matrix renormalization group (TMRG) algorithms and present results for quantities like particle nu…
