DBI scalar field theory for QGP hydrodynamics [PDF]
Physical Review D, 2016 A way to describe the hydrodynamics of the quark-gluon plasma using a DBI action is proposed, based on the model found by Heisenberg for high energy scattering of nucleons. The expanding plasma is described as a shockwave in a DBI model for a real scalar standing in for the pion, and I show that one obtains a fluid description in terms of a ...

Thermalization and chaos in a 1+1d QFT
Journal of High Energy Physics, 2023 We study aspects of chaos and thermodynamics at strong coupling in a scalar model using LCT numerical methods. We find that our eigenstate spectrum satisfies Wigner-Dyson statistics and that the coefficients describing eigenstates in our basis satisfy ...

Lifshitz field theories at non-zero temperature, hydrodynamics and gravity [PDF]
Journal of High Energy Physics, 2014 We consider a covariant formulation of field theories with Lifshitz scaling, and analyze the energy-momentum tensor and the scale symmetry Ward identity. We derive the equation of state and the ideal Lifshitz hydrodynamics in agreement with arXiv:1304.7481, where they were determined by using thermodynamics and symmetry properties.

Hydrodynamic Self-Consistent Field Theory for Inhomogeneous Polymer Melts [PDF]
Physical Review Letters, 2006 We introduce a mesoscale technique for simulating the structure and rheology of block copolymer melts and blends in hydrodynamic flows. The technique couples dynamic self consistent field theory (DSCFT) with continuum hydrodynamics and flow penalization to simulate polymeric fluid flows in channels of arbitrary geometry.

Spectra of correlators in the relaxation time approximation of kinetic theory
Journal of High Energy PhysicsThe relaxation time approximation (RTA) of the kinetic Boltzmann equation is likely the simplest window into the microscopic properties of collective real-time transport.

A Model for Hydrodynamics in Kinetic Field Theory
, 2018 In this work, we introduce an effective model for both ideal and viscous fluid dynamics within the framework of kinetic field theory (KFT). The main application we have in mind is cosmic structure formation where gaseous components need to be gravitationally coupled to dark matter. However, we expect that the fluid model is much more widely applicable.

Relaxation terms for anomalous hydrodynamic transport in Weyl semimetals from kinetic theory
Journal of High Energy PhysicsWe consider as a model of Weyl semimetal thermoelectric transport a (3 + 1)-dimensional charged, relativistic and relaxed fluid with a U(1) V × U(1) A chiral anomaly.

Relativistic Hydrodynamic Scaling from the Dynamics of Quantum Field Theory [PDF]
Physical Review Letters, 2002 Relativistic hydrodynamic scaling or boost invariance is a particularly important hydrodynamic regime, describing collective flows of relativistic many body systems and is used in the interpretation of experiments from high-energy cosmic rays to relativistic heavy-ion collisions.

Causality in dissipative relativistic magnetohydrodynamics
Journal of High Energy PhysicsWe explore the relationship between linear and non-linear causality in theories of dissipative relativistic fluid dynamics. While for some fluid-dynamical theories, a linearized causality analysis can be used to determine whether the full non-linear ...
