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…
A note on the canonical approach to hydrodynamics and linear response theory
Luca Martinoia, Rajeev Singh
This note provides a comprehensive examination of the various approaches to formulating relativistic hydrodynamics, with a particular emphasis on the canonical approach. Relativist…
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…
