Khemani's research focuses on non-equilibrium many-body quantum dynamics. As part of her doctoral research, Khemani was part of a team that identified a novel non-equilibrium phase of matter, which is now known as a Floquet time-crystal. Such crystals demonstrate spontaneous breaking of time translation symmetry. In conventional crystals, atoms are arranged in regular and ordered patterns, whereas in time crystals they are arranged in both space and time.
