Relativistic hydrodynamics under rotation: Prospects and limitations from a holographic perspective
The AdS/CFT correspondence, or holography, has provided numerous important insights
into the behavior of strongly-coupled many-body systems. Crucially, it has provided a testing …

Analytic structure of diffusive correlation functions
S Grozdanov, T Lemut, J Pelaič, A Soloviev - Physical Review D, 2024 - APS
Diffusion is a dissipative transport phenomenon ubiquitously present in nature. Its details
can now be analyzed with modern effective field theory (EFT) techniques that use the closed …

Nearly critical superfluid: effective field theory and holography
Y Bu, H Gao, X Gao, Z Li - Journal of High Energy Physics, 2024 - Springer
A bstract We study a nearly critical superfluid system from two complementary approaches.
Within the first approach, we formulate a Schwinger-Keldysh effective field theory (EFT) for …

Schwinger-Keldysh effective action for hydrodynamics with approximate symmetries
We study the hydrodynamic theories with approximate symmetries in the recently developed
effective action approach on the Schwinger-Keldysh (SK) contour. We employ the method of …

Holographic Schwinger-Keldysh effective field theories including a non-hydrodynamic mode
We derive the Schwinger-Keldysh effective field theories for diffusion including the lowest
non-hydrodynamic degree of freedom from holographic Gubser-Rocha systems. At low …

Three-point functions from a Schwinger-Keldysh effective action, resummed in derivatives
N Abbasi, DH Rischke - arXiv preprint arXiv:2410.07929, 2024 - arxiv.org
The search for the conjectured QCD critical point in heavy-ion collisions requires to account
for far-from equilibrium effects as well as fluctuations, and in particular non-Gaussian …

Stochastic fluctuations and the relaxation time in transient relativistic fluids
GS Denicol, J Noronha - arXiv preprint arXiv:2406.15569, 2024 - arxiv.org
We argue that the ratio between the shear viscosity and the shear relaxation time,
$\eta/\tau_\pi $, should be defined as a thermodynamic quantity obtained from the equal …
