A 11: Thermodynamics and dynamics of one-dimensional quantum systems

In this project we will study the thermodynamical and dynamical properties of two classes of quasi one-dimensional systems: (a) We will use numerical and analytical techniques to investigate the time evolution of a prepared initial state as well as equilibrium dynamical two-point correlation functions at finite temperatures in bosonic  models.

(b) In the second part of the project, the thermodynamics of  frustrated spin models consisting of chains with a weak frustrating  interchain coupling will be studied.

A particular focus of the dynamical studies will be on experimental systems consisting of ultracold bosons on optical lattices (Ott (A9))  and ion crystals in micro traps (Schmidt-Kaler (A10)). Our studies  will complement alternative theoretical approaches in (Fleischhauer/ Eggert (A5), Hofstetter (A3), and Kopietz (A8)). The second part of  the project will focus on Cs_2CuCl_{4-x}Br_x and related materials  which are experimentally studied in projects (Wolf/Lang (B1), and  Ritter/Assmus (B4)). Complementary theoretical studies on such systems  will be performed in (Jeschke/Valenti (B2)) and (Eggert (B3)).
