The price of locality: Maxwell-Cattaneo charge transport in Schwinger-Keldysh effective field theory
Andrea Amoretti, Matteo Anselmi, Daniel K. Brattan
We determine the conditions under which the nonlinear Maxwell-Cattaneo theory of charge transport admits a local Gaussian Schwinger-Keldysh embedding with a particular modified dyn…
Staying positive: bounds for non-Gaussian noise in Schwinger-Keldysh effective field theory
Andrea Amoretti, Daniel K. Brattan
Modern effective field theories of dissipative hydrodynamics, built on the Schwinger-Keldysh (SK) formalism, include thermal noise that is not Gaussian. The resultant higher-order…
The Hamiltonian mechanics of exotic particles
Andrea Amoretti, Daniel K. Brattan, Luca Martinoia
We develop Hamiltonian mechanics on Aristotelian manifolds, which lack local boost symmetry and admit absolute time and space structures. We construct invariant phase space dynamic…
Dissipative electrically driven fluids
Andrea Amoretti, Daniel K. Brattan, Luca Martinoia +1
We consider entropy generating flows for fluids that achieve a steady state in the presence of a driving electric field. Having chosen one among the space of stationarity constrain…
Thermodynamic constraints and exact scaling exponents of flocking matter
Andrea Amoretti, Daniel K. Brattan, Luca Martinoia
We use advances in the formalism of boost agnostic passive fluids to constrain transport in polar active fluids, which are subsequently described by the Toner-Tu equations. Acknowl…
Relaxed hydrodynamic theory of electrically driven non-equilibrium steady states
Daniel K. Brattan, Masataka Matsumoto, Matteo Baggioli +1
The capability of hydrodynamics to accurately describe slow and long-wavelength fluctuations around non-equilibrium steady states (NESS), characterized by a stationary flow of ener…
