Research

My field of research is Condensed Matter Physics and my research spans a variety of systems ranging from complex materials to artificially-designed/tunable devices. An overview of my research philosophy can be found under the home tab and a detailed technical description can be found in my publications. Here I seek to provide a bridge between these two.

The underlying theme in my research has been to advance the understanding of (strong) correlations, quantum and thermal fluctuations, (dis)order, (de)coherence, dissipation, and departure from equilibrium in quantum condensed-matter systems. My approach to research has been to identify and investigate questions of a fundamental nature that are also of experimental relevance and of potential technological and societal importance.

Studies of (non-equilibrium) transport and dynamics have historically played an important role in offering deep insights about the properties of a variety of systems and are the ones that naturally lend themselves to designing, building, measuring and developing devices, memories, circuitry and a host of technological applications. Experimental and technological advances have in turn made these studies, that form a common thread in majority of my research, particularly exciting and rewarding. From my perspective, the fact that everything in the natural world is in a state of flux adds further appeal to this pursuit.

My research projects can be classified into the following system types:

I. Low-Dimensional and Nano-scale Superconductors

II. Hybrid Structures and Devices (mainly with superconductor as a component)

III. Quantum Dot Devices, Magnetic Nanostructures, etc.

IV. Complex Bulk Materials

Currently I have ongoing projects in I-III, some with motivation from and anticipated extensions and applications to IV. Similarly, the research projects in I-III have cross-connections and synergistic relations ranging from obvious to subtle.
