Early life and education

Khemani was born in India and was educated through high-school at La Martiniere Calcutta. She moved to the United States to study physics at Harvey Mudd College, where she completed a senior thesis on gravitational holography. Her undergraduate thesis was awarded the Thomas Benjamin Brown Memorial Award. Alongside her physics course, Khemani completed courses in economics, linguistics and creative writing.[1] She also took part in robotics programmes and competed at national robotics competitions. After completing her undergraduate degree in 2010, she moved to Princeton University as a graduate student.[1] Here she worked on non-equilibrium phases of matter in Floquet crystals.

Research and career

As part of her doctoral research, Khemani was part of a team that identified a novel phase of matter, which is now known as a Floquet time-crystal. Such crystals demonstrate spontaneous breaking of time translation symmetry.[2][3] In conventional crystals, atoms are arranged in regular and ordered patterns, whereas in time crystals they are arranged in both space and time.[3][4] In 2016, Khemani was made a Harvard Junior Fellow in the Harvard Society of Fellows.[5][6]

Princeton postdoctoral researcher Curt von Keyserlingk, who contributed additional theoretical work with Khemani and Sondhi, said, "We explained how the time crystal systems lock into the persistent oscillations that signify a spontaneous breaking of time translation symmetry." Additional work by researchers at Microsoft's Station Q and the University of California-Berkeley led to further understanding of time crystals. As a result of these theoretical studies, two groups of experimenters began attempting to build time crystals in the laboratory.
