Entropy production, hydrodynamics, and resurgence in the primordial quark-gluon plasma from holography [PDF]
Physical Review D, 2016 Microseconds after the Big Bang quarks and gluons formed a strongly coupled nonconformal liquid driven out of equilibrium by the expansion of the Universe.

Pseudo-spontaneous U(1) symmetry breaking in hydrodynamics and holography [PDF]
Journal of High Energy Physics, 2022 We investigate the low-energy dynamics of systems with pseudo-spontaneously broken U(1) symmetry and Goldstone phase relaxation. We construct a hydrodynamic framework which is able to capture these, in principle independent, effects.

Relativistic hydrodynamic attractors with broken symmetries: non-conformal and non-homogeneous
Journal of High Energy Physics, 2017 Standard textbooks will state that hydrodynamics requires near-equilibrium to be applicable. Recently, however, out-of-equilibrium attractor solutions for hydrodynamics have been found in kinetic theory and holography in systems with a high degree of ...

Hydrodynamics, spin currents and torsion
Journal of High Energy Physics, 2023 We construct the canonical constitutive relations for a fluid description of a system with a spin current, valid in an arbitrary number of dimensions in the absence of parity breaking or time reversal breaking terms. Our study encompasses the hydrostatic

Holography and magnetohydrodynamics with dynamical gauge fields
Journal of High Energy Physics, 2023 Within the framework of holography, the Einstein-Maxwell action with Dirichlet boundary conditions corresponds to a dual conformal field theory in presence of an external gauge field.

Evolutions in first-order viscous hydrodynamics
, 2022 Motivated by the physics of the quark-gluon plasma created in heavy-ion collision experiments, we use holography to study the regime of applicability of various theories of relativistic viscous hydrodynamics. Using the microscopic description provided by

Non-dissipative electrically driven fluids
Journal of High Energy Physics, 2023 Existing hydrodynamic models of charged fluids consider any external electric field acting on the fluid as either first order in the hydrodynamic derivative expansion and completely arbitrary or zeroth order but constrained by the fluid’s chemical ...

Novel semi-circle law and Hall sliding in a strongly interacting electron liquid
Journal of High Energy Physics, 2022 We study a strongly interacting, fermionic fluid in the presence of an applied magnetic field using a holographic framework. At low temperatures, translation symmetry is spontaneously broken and the resulting phase is a striped Hall fluid.

Bubble wall velocity from holography [PDF]
, 2022 Cosmological phase transitions proceed via the nucleation of bubbles that subsequently expand and collide. The resulting gravitational wave spectrum depends crucially on the bubble wall velocity.

Aspects of univalence in holographic axion models
Journal of High Energy Physics, 2022 Univalent functions are complex, analytic (holomorphic) and injective functions that have been widely discussed in complex analysis. It was recently proposed that the stringent constraints that univalence imposes on the growth of functions combined with ...
