Arunava Chakrabarti

Professor and Head of the Department

I am primarily interested in theoretical Condensed Matter Physics. Special interest has so far been in the physics of localization and de-localization of excitations in quasi-periodic, disordered and deterministic fractal lattices. Currently struggling to understand  topological phase transition in quasi-one dimensional decorated lattice models with a hidden SSH character, and in the presence of an external perturbing field, a magnetic field for example. Together with it, spin polarized transport in quasi-one dimensional model systems, with emphasis on Chiral Induced Spin Selectivity (CISS) effect in molecular systems are occupying me. Flat, non-dispersive bands in quasi-one dimensional, and two dimensional model lattices have also kept me busy for some time now. Very recently, we could propose several random or deterministically disordered lattice topologies, where a minimal quasi one dimensionalty and/or an external magnetic field caused a complete de-localization of single particle states, much in contrast to the canonical case of Anderson localization. Such systems are currently being built in Heriott-Watt University in Edinburgh using ultra-fast Laser writing tecniques, and the preliminary experiments corroborate our work back in India.
