focus on applications in heavy ion collisions and the quark gluon plasma. Pedagogical …

Stochastic fluctuations in relativistic fluids: Causality, stability, and the information current

N Mullins, M Hippert, J Noronha - Physical Review D, 2023 - APS
We develop a general formalism for introducing stochastic fluctuations around
thermodynamic equilibrium which takes into account, for the first time, recent developments …

Approximate symmetries, pseudo-Goldstones, and the second law of thermodynamics

J Armas, A Jain, R Lier - Physical Review D, 2023 - APS
We propose a general hydrodynamic framework for systems with spontaneously broken
approximate symmetries. The second law of thermodynamics naturally results in relaxation …

Collective dynamics and the Anderson-Higgs mechanism in a bona fide holographic superconductor

HS Jeong, M Baggioli, KY Kim, YW Sun - Journal of High Energy Physics, 2023 - Springer
A bstract The holographic superconductor is one of the most popular models in the context
of applied holography. Despite what its name suggests, it does not describe a …

Pseudo-spontaneous U (1) symmetry breaking in hydrodynamics and holography

M Ammon, D Arean, M Baggioli, S Gray… - Journal of High Energy …, 2022 - Springer
A bstract We investigate the low-energy dynamics of systems with pseudo-spontaneously
broken U (1) symmetry and Goldstone phase relaxation. We construct a hydrodynamic …

Colloquium: Hydrodynamics and holography of charge density wave phases

M Baggioli, B Goutéraux - Reviews of Modern Physics, 2023 - APS

phases of matter with spontaneously broken translations, such as charge density waves or …

Signatures of moat regimes in heavy-ion collisions

RD Pisarski, F Rennecke - Physical Review Letters, 2021 - APS
Heavy-ion collisions at small beam energies have the potential to reveal the rich phase
structure of QCD at low temperature and nonzero density. In this case spatially modulated …

Pion dynamics in a soft-wall AdS-QCD model

X Cao, M Baggioli, H Liu, D Li - Journal of High Energy Physics, 2022 - Springer
A bstract Pseudo-Goldstone modes appear in many physical systems and display robust
universal features. First, their mass m obeys the so-called Gell-Mann-Oakes-Renner …

Dissipation dynamics of a scalar field

L Batini, E Grossi, N Wink - Physical Review D, 2023 - APS
We investigate the dissipation rate of a scalar field in the vicinity of the phase transition and
the ordered phase, specifically within the universality class of model A. This dissipation rate …

Causality and stability of relativistic spin hydrodynamics

G Sarwar, M Hasanujjaman, JR Bhatt, H Mishra, J Alam - Physical Review D, 2023 - APS
We study the causality and stability of relativistic hydrodynamics with the inclusion of the
spin degree of freedom as a hydrodynamic field. We consider two specific models of spin …
