Gauge transformations and Galilean covariance in nonlinear gauge-coupled quantum fluids
Yvan Buggy, Patrik Öhberg
We investigate certain invariance properties of quantum fluids subject to a nonlinear gauge potential. In particular, we derive the covariant transformation laws for the nonlinear…
Hydrodynamics of nonlinear gauge-coupled quantum fluids
Y. Buggy, L. G. Phillips, P. Öhberg
By constructing a hydrodynamic canonical formalism, we show that the occurrence of an arbitrary density-dependent gauge potential in the meanfield Hamiltonian of a Bose-condensed f…
On the hydrodynamic canonical formalism of the Gross-Pitaevskii field
Yvan Buggy, Patrik Öhberg
We derive a canonical formalism for the hydrodynamic representation of the Gross-Pitaevskii field (nonlinear Schrödinger field), where the density and the phase of the condensate f…
On the hydrodynamics of Bose-condensed fluids subject to density-dependent gauge potentials
Yvan Buggy, Patrik Öhberg
When the energy functional of a Bose-condensed state of matter features an effective gauge potential which depends on the density of the condensate, the kinetic energy density…
