About

Biography

I embarked on a career in physics research with an Engineering Physics degree from the Indian Institute of Technology Bombay, India. I worked on the effects of disorder in superfluid helium-3 as the topic of my PhD thesis in theoretical condensed matter physics at Northwestern University, USA. Subsequently, I held a Leverhulme Early Career Fellowship at Royal Holloway University of London where I studied the effects of surface roughness in confined helium-3. I was awarded a Fellowship from the Department of Science and Technology, Government of India and worked at the Indian Institute of Science, Bangalore on theoretical studies of disordered Fermi liquids. More recently, I developed a proposal to study the interaction of qubits with superfluid helium-3 and currently hold a Daphne Jackson Fellowship to pursue this investigation at the ��Vlog.

Areas of specialism

Thanks to Prof. Jim Al-Khalili, CBE FRS HonFREng HonFIET HonFinstP, for producing this Short (2-min video) on my invention of a new type of quantum bit, that could be used to make quantum computers.

Research

Research interests

I am interested in one of the paradigms for complex symmetry-breaking in topologically ordered systems, superfluid helium-3. I have worked on the effects of disorder and confinement, which have fascinating consequences in this quantum system. I am a theorist and work on the mechanisms and implications of superconductivity and superfluidity. I have recently invented a superfluid-based quantum device that could function as a novel qubit.
