We use Lagrangian effective field theory techniques to construct the equations of motion for an ideal relativistic fluid whose constituent degrees freedom have microscopic polarization. discuss meaning such a system, and argue that it is first term in EFT appropriate describing polarization observables heavy ion collisions, as final state particle chiral magnetic vortaic effects. show this system will generally require non-dissipative dynamics at higher order gradient than second order,...

We analyze the breakdown of causality for perfect fluid limit in a medium with polarizeability. show that to restore relaxation term linking vorticity and polarization, analogous Israel-Stewart viscous forces gradients,is required. This provides minimum amount dissipation locally thermalized relativistic polarizeability must have, independently its underlying degrees freedom. For ferromagnetic materials an infrared acausal mode remains, which we interpret as Banks-Casher signaling...

We use linear response techniques to develop the previously proposed relativistic ideal fluid limit with a non-negligible spin density. confirm previous results and obtain expressions for microscopic transport coefficients using Kubo-like formulae buld up effective field theory from computed correlation functions. also that polarization makes vortices aquire an mass via mechanism similar Anderson-Higgs in superconductors. As speculated earlier, this could stabilize hydrodynamic against...

We extend the effective theory approach to ideal fluid limit where polarization of is non-zero. After describing and motivating equations motion, we expand them around hydrostatic limit, obtaining sound wave vortex degrees freedom. discuss how presence affects stability causality limit.

We examine the formation of vortical "smoke rings" as a result thermalization energy lost by jet. simulate and evolution these rings using hydrodynamics define an observable that allows to probe this phenomenon experimentally. argue observation vorticity associated with jets would be experimental confirmation quenched jets, also shear viscosity.

We argue that a detailed analysis of the spin alignment vector mesons can serve as probe two little-understood aspects dynamics in vortical fluid: The degree relaxation between vorticity and particle polarization, coherence hadron wave function at freeze-out. illustrate these with coalescence model.

We performed a systematic study on the formation of vorticity rings as process for jet thermalization in medium created high-energy nuclear collisions. In this work, we expanded our previous analysis to more realistic framework by considering noncentral events and fluctuations initial condition. simulate evolution flow vortex structure relativistic viscous hydrodynamic model sensitivity proposed ``ring observable'' $({\mathcal{R}}_{\mathrm{\ensuremath{\Lambda}}}^{t})$ that can be measured...

We demonstrate how chiral oscillations of a massive Dirac field can be described within quantum theory using finite-time interaction picture approach, where the mass term in Lagrangian is treated as perturbative coupling between massless fields definite chirality. derive formula for at fourth order expansion, obtaining result consistent with derived by means other methods. Furthermore, we illustrate framework effectively describe production processes an electron must exhibit both left...

Relativistic p+A collisions may produce droplets of quark gluon plasma (QGP) that quickly develop a toroidal vortex structure similar to an expanding smoke ring. We present viscous relativistic hydrodynamic calculations ultra-central and experimental observable probe the structure, correlating polarization momentum hyperons emitted from collision. The effect is robust against changes in definition vorticity used calculate polarization. Experiments at RHIC LHC test existence strength toroids,...

We use a potential model to investigate the phenomenology of quarkonium in thermal rotating medium, where vorticity and spin density are not necessarily equilibrium. find that matrix, as well binding energy melting temperature, sensitive both lack equilibrium between spin. This means alignment is probe for within hydrodynamic phase. Information unequivocally pointing spin-orbit nonequilibrium dynamics can be obtained from combined study relative abundance alignment, experimentally obtainable...

We show that volume-preserving diffeomorphisms and the chemical shift symmetry defining relativistic Lagrangian ideal fluid dynamics can be derived as an emerging when ergodicity is assumed to apply locally in a way invariant under smooth spacetime foliations. This used derive hydrodynamic limit strongly coupled but fluctuating medium. comment on connection with thermalization small systems, eigenstate hypothesis deviations from limit.

We show that far zone Mach and diffusion wake "holograms" produced by supersonic strings in anti-de Sitter space/conformal field theory (AdS/CFT) correspondence do not lead to observable conical angular correlations the strict N_{c}-->infinity supergravity limit if Cooper-Frye hadronization is assumed. However, a special nonequilibrium "neck" near jet shown produce an apparent sonic boom azimuthal angle distribution roughly independent of heavy quark's velocity. Our results indicate...

We rederive relativistic hydrodynamics as a Lagrangian effective theory using the doubled coordinates technique, allowing us to include dissipative terms. Navier-Stokes shear and bulk terms, well Israel-Stewart relaxation time within this formalism. show how inclusion of dissipation forces term into theory, thereby providing an additional justification for form term.

We formulate a Lagrangian hydrodynamics including shear and bulk viscosity in the presence of spin density, investigate it using linear response functional formalism. The result is careful accounting all sound vortex interactions close to local equilibrium. In particular, we demonstrate that mixing waves vortices via polarization, first observed ideal fluid limit, extends mode once dissipative effects are included. This provides realization within symmetric polarization contribution recently...

We argue that one can model deviations from the ensemble average in non-equilibrium statistical mechanics by promoting Boltzmann equation to an terms of functionals , representing possible candidates for phase space distributions inferred a finite observed number degrees freedom. find that, provided collision term and Vlasov drift are both included, gauge-like redundancy arises which does not go away even if functional is narrow. this effect linked symmetry found relativistic hydrodynamics...

Abstract We study the mixing of different kind fields (scalar in 0+1D, scalar 3+1D, fermion 3+1D) treating term as an interaction. To this aim, we employ usual perturbative series interaction picture. find that expression for flavor changing probability exhibits corrections with respect to quantum mechanical (e.g. neutrino) oscillation formula, agreement result previously obtained non-perturbative Fock space approach.

A bstract We use the Crooks fluctuation theorem [1, 2] together with Zubarev hydro- dynamics [3] to develop a bottom-up theory of hydrodynamic fluctuations. also thermodynamic uncertainity relations estimate limits dissipative transport coefficients.
