Research Activities

The collective effects of multicomponent glasses is studied at very low temperature. We are trying to explain the unexpected dielectric and pulse echo response of this system in the presence of magnetic field. We have introduced any XY type of interaction to be responsible for this effects. In this study we implement Lanczox exact diagonalization for studying few tunneling centers.

Present Research Project at IPM

Coherent Motion in Cold Glasses.
