One dimensional systems have been of long standing interest due to a profound difference from their 2 and 3 dimensional counterparts whose properties can be described in terms of quasi-particles. This quasi-particle picture breaks down completely in one dimension where the fundamental excitations are collective and described by the universal Tomonaga-Luttinger liquid (TLL) theory. The research team will develop, optimize and explore a novel platform for TLL physics. Our group, in collaboration with the theory group of Adrian Del Maestro (University of Vermont) are studying the properties of

### Structure and Dynamics of Confined Solids

Porous materials are playing an increasingly important role as a fertile playground for the exploration of fundamental scientific issues and diverse technological applications. Surface interactions and finite size effects play a key role in the qualitative modification of the properties of the materials contained within the porous host. On the practical level, such systems are of great importance in a variety of situations, ranging from adhesion, catalysis, lubrication, tribology and the engineering of materials. We utilize x-ray and neutron scattering to study the preoerties of these systems. |
