Linear dynamical stability and the laws of thermodynamics
Blaise Goutéraux, Eric Mefford
We show that the dynamical stability under linear perturbations of interacting systems in the hydrodynamic regime follows from the first and the second laws of thermodynamics. Our…
Dipole superfluid hydrodynamics II
Akash Jain, Kristan Jensen, Ruochuan Liu +1
We present a dissipative hydrodynamic theory of "s-wave dipole superfluids" that arise in phases of translation-invariant and dipole-symmetric models in which the U(1) symmetry is…
Hydrodynamics and instabilities of relativistic superfluids at finite superflow
Daniel Areán, Blaise Goutéraux, Eric Mefford +1
We study the linear response of relativistic superfluids with a non-zero superfluid velocity. For sufficiently large superflow, an instability develops via the crossing of a pole o…
Dipole superfluid hydrodynamics
Akash Jain, Kristan Jensen, Ruochuan Liu +1
We construct a theory of hydrodynamic transport for systems with conserved dipole moment, U(1) charge, energy, and momentum. These models have been considered in the context of fra…
Jackiw-Teitelboim quantum gravity with defects and the Aharonov-Bohm effect
Eric Mefford, Kenta Suzuki
We study the theory of Jackiw-Teitelboim gravity with generalized dilaton potential on Euclidean two-dimensional negatively curved backgrounds. The effect of the generalized dilato…
Non-vanishing normal density in cold holographic superfluids
Blaise Goutéraux, Eric Mefford
The low energy and finite temperature excitations of a -dimensional system exhibiting superfluidity are well described by a hydrodynamic model with two fluid flows: a normal f…
