Welcome to my homepage

Before boring you with all my professional information here is some entertaining starter

My field of interest is theoretical quantum condensed matter physics. The systems I study are cold atomic condensates, two dimensional electronic systems such as Quantum Hall systems and Graphene, As an application I am interested how qubits can be formed in such systems and how quantum information processing can be achieved with such systems. I teach Quantum Mechnaics, Statistical mechanics and Condensed Matter Physics at undergraduate and post-graduate level. Here are a little more general informations about various fields of interest

1. Cold atomic gases (A useful site for BEC watchers)

2. Graphene (To know more about graphene click here)

3. Mono and Bi-layer Quantum Hall Systems in semiconductor hetero-structures

4. Quantum Computation and Quantum Information processing ( link to a popular article on topological quantum computation)

A DST funded project has been recently approved on the “ Electron Transport in Graphene” The project has a position of Research Associate for three years

and will be soon advertised. Interested candidates may contact ( either me or Dr. Manish Sharma at CARE, IITD) and apply at the appropriate time.

The information regarding the official advertisement will also be available at this website.
