Convexity and liberation at large spin

- Z. Komargodski, A. Zhiboedov
- Physics
- 17 December 2012

A bstractWe consider several aspects of unitary higher-dimensional conformal field theories (CFTs). We first study massive deformations that trigger a flow to a gapped phase. Deep inelastic… Expand

On renormalization group flows in four dimensions

- Z. Komargodski, A. Schwimmer
- Physics
- 20 July 2011

A bstractWe discuss some general aspects of renormalization group flows in four dimensions. Every such flow can be reinterpreted in terms of a spontaneously broken conformal symmetry. We analyze in… Expand

From Linear SUSY to Constrained Superfields

- Z. Komargodski, N. Seiberg
- Physics
- 15 July 2009

We present a new formalism for finding the low-energy effective Lagrangian of Goldstinos and other fields. This Lagrangian is written using standard superspace and the superfields are constrained to… Expand

Supersymmetric field theories on three-manifolds

- C. Closset, T. Dumitrescu, G. Festuccia, Z. Komargodski
- Physics, Mathematics
- 14 December 2012

A bstractWe construct supersymmetric field theories on Riemannian three-manifolds $ \mathcal{M} $, focusing on $ \mathcal{N} $ = 2 theories with a U(1)R symmetry. Our approach is based on the rigid… Expand

Comments on supercurrent multiplets, supersymmetric field theories and supergravity

- Z. Komargodski, N. Seiberg
- Physics
- 11 February 2010

We analyze various supersymmetry multiplets containing the supercurrent and the energy-momentum tensor. The most widely known such multiplet, the Ferrara-Zumino (FZ) multiplet, is not always… Expand

Exactly marginal deformations and global symmetries

- D. Green, Z. Komargodski, N. Seiberg, Yuji Tachikawa, B. Wecht
- Physics
- 19 May 2010

We study the problem of finding exactly marginal deformations of $ \mathcal{N} = 1 $ superconformal field theories in four dimensions. We find that the only way a marginal chiral operator can become… Expand

The constraints of conformal symmetry on RG flows

- Z. Komargodski
- Physics
- 20 December 2011

A bstractIf the coupling constants in QFT are promoted to functions of space-time, the dependence of the path integral on these couplings is highly constrained by conformal symmetry. We begin the… Expand

Contact terms, unitarity, and F -maximization in three-dimensional superconformal theories

- C. Closset, T. Dumitrescu, G. Festuccia, Z. Komargodski, N. Seiberg
- Physics
- 18 May 2012

A bstractWe consider three-dimensional $ \mathcal{N}=2 $ superconformal field theories on a threesphere and analyze their free energy F as a function of background gauge and supergravity fields. A… Expand

Theta, time reversal and temperature

- D. Gaiotto, A. Kapustin, Z. Komargodski, N. Seiberg
- Physics
- 1 March 2017

A bstractSU(N ) gauge theory is time reversal invariant at θ = 0 and θ = π. We show that at θ = π there is a discrete ’t Hooft anomaly involving time reversal and the center symmetry. This anomaly… Expand

A symmetry breaking scenario for QCD3

- Z. Komargodski, N. Seiberg
- Physics
- 27 June 2017

A bstractWe consider the dynamics of 2+1 dimensional SU(N) gauge theory with Chern-Simons level k and Nf fundamental fermions. By requiring consistency with previously suggested dualities for Nf ≤ 2k… Expand
