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…
Domain wall moduli in softly-broken SQCD at
Adam Ritz, Ashish Shukla
We analyze the moduli space dynamics of domain walls in QCD at , by softly breaking SQCD with sfermion mixing. In the supersymmetric limit, BPS d…
Black hole energy extraction via stationary scalar clouds
Jordan Wilson-Gerow, Adam Ritz
We study scalar field configurations around Kerr black holes with a time-independent energy-momentum tensor. These stationary `scalar clouds', confined near the black hole (BH) by…
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…
Kerr-AdS Black Holes and Force-Free Magnetospheres
Xun Wang, Adam Ritz
We obtain analogs of the Blandford-Znajek split monopole solution for force-free magnetospheres around a slowly rotating Kerr-AdS black hole. For small black holes, we find an anal…
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…
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…
Weyl corrections to holographic conductivity
Adam Ritz, John Ward
For conformal field theories which admit a dual gravitational description in anti-de Sitter space, electrical transport properties, such as conductivity and charge diffusion, are d…
Dyon dynamics near marginal stability and non-BPS states
Adam Ritz, Arkady Vainshtein
We derive the general form of the moduli-space effective action for the long-range interaction of two BPS dyons in N=2 gauge theories. This action determines the bound state struct…
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…
Superconformal R-charges and dyon multiplicities in N=2 gauge theories
Adam Ritz
N=(2,2) theories in 1+1D exhibit a direct correspondence between the R-charges of chiral operators at a conformal point and the multiplicities of BPS kinks in a massive deformation…
Central charges, S-duality and massive vacua of N=1* super Yang-Mills
Adam Ritz
We provide a simple derivation of the extremal values of the superpotential in massive vacua of N=1* SYM, making use of the required modular weight for the central charge of BPS wa…
Enhanced Worldvolume Supersymmetry and Intersecting Domain Walls in N=1 SQCD
A. Ritz, M. Shifman, A. Vainshtein
We study the worldvolume dynamics of BPS domain walls in N=1 SQCD with N_f=N flavors, and exhibit an enhancement of supersymmetry for the reduced moduli space associated with broke…

We study the multiplicity of BPS domain walls in N=1 super Yang-Mills theory, by passing to a weakly coupled Higgs phase through the addition of fundamental matter. The number of d…

In two dimensional conformal field theory the generating functional for correlators of the stress-energy tensor is given by the non-local Polyakov action associated with the backgr…
Long Range Forces and Supersymmetric Bound States
Adam Ritz, Arkady Vainshtein
We consider the long range forces between two BPS particles on the Coulomb branch of N=2 and N=4 supersymmetric gauge theories. The 1/r potential is unambiguously fixed, even at st…
Marginal Stability and the Metamorphosis of BPS States
Adam Ritz, Mikhail Shifman, Arkady Vainshtein +1
We discuss the restructuring of the BPS spectrum which occurs on certain submanifolds of the moduli/parameter space -- the curves of the marginal stability (CMS) -- using quasiclas…
Instantons at Strong Coupling, Averaging over Vacua, and the Gluino Condensate
Adam Ritz, Arkady Vainshtein
We consider instanton contributions to chiral correlators, such as <0| Tr λ^2 (x) Tr λ^2(x') |0>, in N=1 supersymmetric Yang-Mills theory with either light adjoint or fundamental m…
