Description

SCOPE
Low-dimensional quantum systems as we understand them are spatially one- or two-dimensional many-body systems. In nature they are realized in strongly anisotropic solids or at their surfaces. In recent years interesting low-dimensional quantum systems can also be artificially created using ultra-cold atoms in traps. Many properties of solids crucially depend on their effective dimensionality. Examples for non-interacting systems are the nature of van-Howe singularities at band edges or the sheer possibility of Bose condensation (impossible in 1d, at T = 0 in 2d, at T > 0 in 3d). For interacting systems the implications of the effective dimensionality are even more severe. In one- and two-dimensional systems we have phases and elementary excitations which do not exist in higher dimensions. This has serious consequences e.g. for the transport properties or for the relaxation dynamics of such systems.

In this workshop we aim to bring together experimentalists and theorists interested in low-dimensional quantum systems realized in solids and systems of ultra-cold atoms. For their mutual benefit we hope for an intensive exchange between theory and experiment. Subjects to be discussed will include
Heat and spin transport in low-dimensional quantum magnets
Current methodological developments in theory and experiment
Calculation and measurement of correlation functions in equilibrium systems
Relaxation dynamics of local observables in integrable many-body systems
Dimensional cross-over
Low-dimensional systems as edge systems
Applications of low-dimensional quantum systems
