Fluctuating relativistic dissipative hydrodynamics as a gauge theory

چکیده
We argue that different formulations of hydrodynamics are related to uncertainties in the definitions local thermodynamic and hydrodynamic variables. show this ambiguity can be resolved by viewing as particular "gauge choices" which lead same physical behavior system. Using example bulk viscosity, we Bemfica-Disconzi-Noronha-Kovtun (BDNK) Israel-Stewart type, a well-defined transformation gauge is necessary ascertain causality stochastic evolution conjecture it could explain applicability outside its expected regime validity since far from equilibrium close may through transformations type.

Causal Theory of Relativistic Dissipative Hydrodynamics
We present a new formalism for the theory of relativistic dissipative hydrodynamics, where covariance and causality are satisfied by introducing the memory effect in irreversible currents. Our theory has a much simpler structure and thus has several advantages for practical purposes compared to the Israel-Stewart theory (IS). We apply our formalism to the Bjorken model and the results are shown...
متن کاملRelativistic fluctuating hydrodynamics
By applying the fluctuation dissipation theorem [1] to the Navier Stokes equation, Landau and Lifshitz developed long ago the standard theory of fluctuating hydrodynamics [2] [3] [4]. This theory is both appealing and successful, and it is consistent with the fluctuating hydrodynamics which is derived if fluctuation dissipation theory is first applied to the Boltzmann equation [5], and then the...
متن کاملA perturbation theory for large deviation functionals in fluctuating hydrodynamics
We study a large deviation functional of density fluctuation by analyzing stochastic non-linear diffusion equations driven by the difference between the densities fixed at the boundaries. By using a fundamental equality that yields the fluctuation theorem, we first relate the large deviation functional with a minimization problem. We then develop a perturbation method for solving the problem. I...
متن کاملRelativistic superfluid hydrodynamics from field theory
It is well known that the hydrodynamics of a zero-temperature superfluid can be formulated in field-theoretic terms, relating for example the superfluid four-velocity to the gradient of the phase of a Bose-condensed scalar field. At nonzero temperatures, where the phenomenology of a superfluid is usually described within a two-fluid picture, this relationship is less obvious. For the case of a ...
متن کاملTemporal Integrators for Fluctuating Hydrodynamics
Including the effect of thermal fluctuations in traditional computational fluid dynamics requires developing numerical techniques for solving the stochastic partial differential equations of fluctuating hydrodynamics. These Langevin equations possess a special fluctuation-dissipation structure that needs to be preserved by spatio-temporal discretizations in order for the computed solution to re...
