Snowmass White Paper: Effective Field Theories for Condensed Matter Systems
Tomas Brauner, Sean A. Hartnoll, Pavel Kovtun +6
We review recent progress and a number of future directions for applications of effective field theory methods to condensed matter systems broadly defined. Our emphasis is on areas…
Causal first-order hydrodynamics from kinetic theory and holography
Raphael E. Hoult, Pavel Kovtun
We show how causal relativistic Navier-Stokes equations arise from the relativistic Boltzmann equation: the causality is preserved via a judicious choice of the zero modes of the c…
Hydrodynamic effective field theory and the analyticity of hydrostatic correlators
Akash Jain, Pavel Kovtun, Adam Ritz +1
We study one-loop corrections to retarded and symmetric hydrostatic correlation functions within the Schwinger-Keldysh effective field theory framework for relativistic hydrodynami…
Non-universality of hydrodynamics
Akash Jain, Pavel Kovtun
We investigate the effects of stochastic interactions on hydrodynamic correlation functions using the Schwinger-Keldysh effective field theory. We identify new "stochastic transpor…
Stable and causal relativistic Navier-Stokes equations
Raphael E. Hoult, Pavel Kovtun
Relativistic Navier-Stokes equations express the conservation of the energy-momentum tensor and the particle number current in terms of the local hydrodynamic variables: temperatur…
First-order relativistic hydrodynamics is stable
Pavel Kovtun
We study linearized stability in first-order relativistic viscous hydrodynamics in the most general frame. There is a region in the parameter space of transport coefficients where…
The complex life of hydrodynamic modes
Sašo Grozdanov, Pavel K. Kovtun, Andrei O. Starinets +1
We study analytic properties of the dispersion relations in classical hydrodynamics by treating them as Puiseux series in complex momentum. The radii of convergence of the series a…
On the convergence of the gradient expansion in hydrodynamics
Sašo Grozdanov, Pavel K. Kovtun, Andrei O. Starinets +1
Hydrodynamic excitations corresponding to sound and shear modes in fluids are characterised by gapless dispersion relations. In the hydrodynamic gradient expansion, their frequenci…
Kubo formulas for thermodynamic transport coefficients
Pavel Kovtun, Ashish Shukla
Uncharged relativistic fluids in 3+1 dimensions have three independent thermodynamic transport coefficients at second order in the derivative expansion. Fluids with a single global…
Relativistic magnetohydrodynamics
Juan Hernandez, Pavel Kovtun
We present the equations of relativistic hydrodynamics coupled to dynamical electromagnetic fields, including the effects of polarization, electric fields, and the derivative expan…
Thermodynamics of polarized relativistic matter
Pavel Kovtun
We give the free energy of equilibrium relativistic matter subject to external gravitational and electromagnetic fields, to one-derivative order in the gradients of the external fi…
On thermal fluctuations and the generating functional in relativistic hydrodynamics
Michael Harder, Pavel Kovtun, Adam Ritz
We discuss a real-time generating functional for correlation functions in dissipative relativistic hydrodynamics which takes into account thermal fluctuations of the hydrodynamic v…
Chiral conductivities and effective field theory
Kristan Jensen, Pavel Kovtun, Adam Ritz
We construct the three-dimensional effective field theory which reproduces low-momentum static correlation functions in four-dimensional quantum field theories with U(1) axial anom…
Lectures on hydrodynamic fluctuations in relativistic theories
Pavel Kovtun
These are pedagogical lecture notes on hydrodynamic fluctuations in normal relativistic fluids. The lectures discuss correlation functions of conserved densities in thermal equilib…
Towards hydrodynamics without an entropy current
Kristan Jensen, Matthias Kaminski, Pavel Kovtun +3
We present a generating functional which describes the equilibrium thermodynamic response of a relativistic system to external sources. A variational principle gives rise to constr…
Parity-Violating Hydrodynamics in 2+1 Dimensions
Kristan Jensen, Matthias Kaminski, Pavel Kovtun +3
We study relativistic hydrodynamics of normal fluids in two spatial dimensions. When the microscopic theory breaks parity, extra transport coefficients appear in the hydrodynamic r…
Black holes and non-relativistic quantum systems
Pavel Kovtun, Dominik Nickel
We describe black holes in d+3 dimensions, whose thermodynamic properties correspond to those of a scale invariant non-relativistic d+1 dimensional quantum system with dynamical ex…
Holographic model of superfluidity
C. P. Herzog, P. K. Kovtun, D. T. Son
We study a holographic model of a relativistic quantum system with a global U(1) symmetry, at non-zero temperature and density. When the temperature falls below a critical value, w…
Universal conductivity and central charges
Pavel Kovtun, Adam Ritz
We discuss a class of critical models in d>1+1 dimensions whose electrical conductivity and charge susceptibility are fixed by the central charge in a universal manner. We comment…
Black holes and universality classes of critical points
Pavel Kovtun, Adam Ritz
We argue that there exists an infinite class of conformal field theories in diverse dimensions, having a universal ratio of the central charge c to the normalized entropy density c…
Hall conductivity from dyonic black holes
Sean A. Hartnoll, Pavel Kovtun
A class of strongly interacting 2+1 dimensional conformal field theories in a transverse magnetic field can be studied using the AdS/CFT duality. We compute zero momentum hydrodyna…
Volume independence in large Nc QCD-like gauge theories
Pavel Kovtun, Mithat Unsal, Laurence G. Yaffe
Volume independence in large $\Nc$ gauge theories may be viewed as a generalized orbifold equivalence. The reduction to zero volume (or Eguchi-Kawai reduction) is a special case of…
Quantum critical transport, duality, and M-theory
Christopher P. Herzog, Pavel Kovtun, Subir Sachdev +1
We consider charge transport properties of 2+1 dimensional conformal field theories at non-zero temperature. For theories with only Abelian U(1) charges, we describe the action of…
Photon and dilepton production in supersymmetric Yang-Mills plasma
Simon Caron-Huot, Pavel Kovtun, Guy Moore +2
By weakly gauging one of the U(1) subgroups of the R-symmetry group, N=4 super-Yang-Mills theory can be coupled to electromagnetism, thus allowing a computation of photon productio…
