Superfluid Field response to Edge dislocation motion
Abdul N. Malmi-Kakkada, Oriol T. Valls, Chandan Dasgupta
We study the dynamic response of a superfluid field to a moving edge dislocation line to which the field is minimally coupled. We use a dissipative Gross-Pitaevskii equation, and d…
Hydrodynamics of compressible superfluids in confined geometries
Abdul N Malmi-Kakkada, Oriol T Valls, Chandan Dasgupta
We present a study of the hydrodynamics of compressible superfluids in confined geometries. We use a perturbative procedure in terms of the dimensionless expansion parameter $(v/v_…
Non-classical Rotational Inertia in a Two-dimensional Bosonic Solid Containing Grain Boundaries
Chandan Dasgupta, Oriol T. Valls
We study the occurrence of non-classical rotational inertia (NCRI) arising from superfluidity along grain boundaries in a two-dimensional bosonic system. We make use of a standard…
