Extreme dynamics and relaxation of quantum gases: A hydrodynamic approach
Ritwik Mukherjee, Abhishek Dhar, Manas Kulkarni +1
The evolution of quantum gases, released from traps, are studied through hydrodynamics, both analytically and numerically, in one and two dimensions. In particular, we demonstrate…
Caustics in the sine-Gordon model from quenches in coupled 1D Bose gases
Aman Agarwal, Manas Kulkarni, D. H. J. O'Dell
Caustics are singularities that occur naturally in optical, hydrodynamic and quantum waves, giving rise to high amplitude patterns that can be described using catastrophe theory. I…
Hydrodynamics of local excitations after an interaction quench in 1D cold atomic gases
Fabio Franchini, Manas Kulkarni, Andrea Trombettoni
We discuss the hydrodynamic approach to the study of the time evolution -induced by a quench- of local excitations in one dimension. We focus on interaction quenches: the considere…
Fluctuating hydrodynamics for a discrete Gross-Pitaevskii equation: mapping to Kardar-Parisi-Zhang universality class
Manas Kulkarni, David A. Huse, Herbert Spohn
We show that several aspects of the low-temperature hydrodynamics of a discrete Gross-Pitaevskii equation (GPE) can be understood by mapping it to a nonlinear version of fluctuatin…
Universal dynamics of a soliton after an interaction quench
Fabio Franchini, Andrey Gromov, Manas Kulkarni +1
We propose a new type of experimentally feasible quantum quench protocol in which a quantum system is prepared in a coherent, localized excited state of a Hamiltonian. During the e…
Cavity-mediated near-critical dissipative dynamics of a driven condensate
Manas Kulkarni, Baris Öztop, Hakan E. Türeci
We investigate the near-critical dynamics of atomic density fluctuations in the non-equilibrium self-organization transition of an optically driven quantum gas coupled to a single…
