Sunil Nair

Associate Professor


Strongly correlated electron systems


Sunil Nair obtained his PhD in experimental condensed matter physics from the Inter University Consortium for DAE facilities, Indore. Following a brief postdoctoral stint at the Tata Institute of Fundamental Research, Mumbai, he moved to the Max Planck Institute for Chemical Physics of Solids in Dresden, as a Humboldt Fellow. He was a Marie Curie fellow at the University of Oxford before joining IISER Pune in 2011.


Experimental condensed matter physics

Electrons in solid state matter interact with each other in myriad ways. Notable consequences of these enigmatic electron-electron interactions include diverse electronic ground states like magnetism, superconductivity, and ferroelectricity. Dr. Sunil Nair's group works on the synthesis of novel multifunctional materials, and in discerning the underlying physical processes which drive these novel electronic states. Of particular interest are systems in which properties can be tuned as a function of external control parameters like temperature, pressure, and magnetic or electric fields.

The group is involved in the synthesis of novel materials, their characterization using a host of laboratory and large scale facilities, as well as the development of specialized instruments to enable such investigations. The broad areas of interest include geometrically frustrated magnets, multiferroics and magnetoelectrics, magnetotransport in unconventional superconductors, materials with large spin-orbit coupling, oxide thermoelectrics and spin caloritronics.
