Education and career

edit

Nayak was born in New York City in 1971. He earned a bachelor’s degree from Harvard University in 1992 and a Ph.D. in physics from Princeton University in 1996.[5][3] His dissertation on “Theories of the half-filled Landau level” was completed under Frank Anthony Wilczek.[3]

In 1996, he was a post-doctoral fellow at the Institute for Theoretical Physics at UCSB and a Professor of Physics at UCLA from 1997 to 2006.[5][8][9]

He joined Microsoft in 2005 as a visiting researcher in Redmond, Washington and the faculty of UCSB in 2007 where he has served as Technical Fellow and Professor of Condensed Matter Theory through 2024.[5][7][10][11]

Nayak has contributed to the theory of topological phases, high-temperature superconductivity, the quantum Hall effect, and phases of periodically-driven quantum systems.[12][13][14][15][16][11][17][18]

Scientific Work

edit

In 1996, Nayak and Wilczek discovered the type of non-Abelian statistics in paired quantum Hall states associated with Majorana zero modes.[16]

In 2005, with Michael Freedman and Sankar Das Sarma, Nayak authored a proposal for a topological qubit using the 5/2 fractional quantum Hall state as the non-Abelian topological state.[14][19]

In 2006 and 2008, Sarma, Freedman and Nayak developed theoretical proposals for topological quantum computing based on non-abelian anyons.[17][11]

In 2011, Nayak, Parsa Bonderson and Victor Gurarie proved that quasiparticles in certain quantized Hall states are non-Abelian anyons, firmly establishing the mathematical foundation of these particles.[12]

In 2016, with Dominic Else and Bela Bauer, he developed Floquet time crystals and predicted its occurrence in periodically-driven systems.[15][18]

Nayak also led research teams in inducing a phase of matter characterized by Majorana zero modes with low enough disorder to pass the topological gap protocol, demonstrating the viability of topological quantum computing. [20]

Recognition

edit

Nayak is a Fellow of the American Physical Society, a recipient of the Outstanding Young Physicist Award from the American Chapter of the Indian Physics Association, an Alfred P. Sloan Foundation Fellowship, and an NSF Early Career Award.[1][2][21][22]
