Vedika Khemani (born 1988) is a theoretical physicist and Associate Professor at Stanford University.[1] Her research lies at the intersection of many-body quantum condensed matter physics and quantum information theory.
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 courses, Khemani completed courses in mathematics, computer science, economics, linguistics and creative writing.[2] She also took part in robotics programs and competed at national robotics competitions.
After completing her undergraduate degree in 2010, she went on to graduate studies at Princeton University.[2] There, she worked with doctoral advisor Shivaji Sondhi.[3] Following her PhD studies, Khemani was a Junior Fellow in the Harvard Society of Fellows.[4][5]
Research and career
Khemani's research focuses on non-equilibrium many-body quantum dynamics. As part of her doctoral research, Khemani identified a novel non-equilibrium phase of matter known as a Floquet time-crystal.[6] Such crystals demonstrate spontaneous breaking of time translation symmetry.[7][8][9] In conventional crystals, atoms are arranged in regular and ordered patterns, whereas in time crystals they are arranged in both space and time.[8][9]

"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."
