QUANTUM INFORMATION THEORY
This is a very interesting area of research in physics. Unfortunately, I have only a very short aquintance with this topic. It was during my stay in Madras University that I was introduced to this topic by my professor Dr.Ranabir Chakrabarthi. Below, I have given the full details of my works.
My MPhil Project
I did my MPhil project on the "Phase Transition in Jaynes-Cummings-Hubbard Model". The work was purely analytical. But I must say it was only a review of some of the papers published on this topic. The Jaynes-Cummings-Hubbard Model is basically a lattice model which describes the physics of atoms or ions placed in optical lattices. Many attempts to experimentally realise the model have been made recently and many of them were successful. This system have importance in Quantum Information Theory since some of the suggested realisations of quantum simulation, concepts like entanglement etc., comes in the way of this model. For a details of what I have done, please see the pdf file of my MPhil project report.
One important aspect of the model which we should always keep in mind is that this is a quantum phase transition. Quantum phase transitions happen due to quantum effect and not by the variation of temperature (as we see in classical phase transitions). In fact there are no thermal effects playing role in the transitions. To avoid thermal effects, these transitions are done at absolute zero.
