A Superfluid at All Temperatures
Sven Harder, Adar Sharon
We construct unitary, local, 3+1-dimensional conformal field theories with finitely many fields whose thermal state breaks a continuous global symmetry at every temperature. They a…
Unveiling dynamical quantum error correcting codes via non-invertible symmetries
Rajath Radhakrishnan, Adar Sharon, Nathanan Tantivasadakarn
Dynamical stabilizer codes (DSCs) have recently emerged as a powerful generalization of static stabilizer codes for quantum error correction, replacing a fixed stabilizer group wit…
A Large Twist Limit for Any Operator
Gwenaël Ferrando, Amit Sever, Adar Sharon +1
We argue that for any single-trace operator in SYM theory there is a large twist double-scaling limit in which the Feynman graphs have an iterative structure. Such str…
A counterexample to the CFT convexity conjecture
Adar Sharon, Masataka Watanabe
Motivated by the weak gravity conjecture, arXiv:2108.04594 conjectured that in any CFT, the minimal operator dimension at fixed charge is a convex function of the charge. In this l…
Onset of Quantum Chaos in Random Field Theories
Micha Berkooz, Adar Sharon, Navot Silberstein +1
We study the quantum Lyapunov exponent in theories with spacetime-independent disorder. We first derive self-consistency equations for the two- and four-point functions for p…
Convexity of Charged Operators in CFTs with Multiple Abelian Symmetries
Eran Palti, Adar Sharon
Motivated by the Weak Gravity Conjecture in the context of holography in AdS, it has been proposed that operators charged under global symmetries in CFTs, in three dimensions or hi…
The onset of quantum chaos in disordered CFTs
Micha Berkooz, Adar Sharon, Navot Silberstein +1
We study the Lyapunov exponent in quantum field theories with spacetime-independent disorder interactions. Generically can only be computed at isolated points in parame…
Non-rational Narain CFTs from codes over
Anatoly Dymarsky, Adar Sharon
We construct a map between a class of codes over and a family of non-rational Narain CFTs. This construction is complementary to a recently introduced relation between quantu…
Squashing, Mass, and Holography for 3d Sphere Free Energy
Shai M. Chester, Rohit R. Kalloor, Adar Sharon
We consider the sphere free energy in ABJ(M) theory deformed by both three real masses and the squashing parameter , which has been computed in…
Full Phase Diagram of a UV Completed Yang-Mills-Chern-Simons Matter Theory
Adar Sharon, Tal Sheaffer
We study the large phase diagram of an asymptotically free UV completion of super-Yang-Mills-Chern-Simons theory coupled to a single massive fundamental…
Transition of Large -Charge Operators on a Conformal Manifold
Adar Sharon, Masataka Watanabe
We study the transition between phases at large -charge on a conformal manifold. These phases are characterized by the behaviour of the lowest operator dimension for fi…
Global Aspects of Spaces of Vacua
Adar Sharon
We study "vacuum crossing", which occurs when the vacua of a theory are exchanged as we vary some periodic parameter in a closed loop. We show that vacuum crossing is a useful…
A Nilpotency Index of Conformal Manifolds
Zohar Komargodski, Shlomo S. Razamat, Orr Sela +1
We show that exactly marginal operators of Supersymmetric Conformal Field Theories (SCFTs) with four supercharges cannot obtain a vacuum expectation value at a generic point on the…
Large N Renormalization Group Flows in 3d Chern-Simons-Matter Theories
Ofer Aharony, Adar Sharon
We discuss 3d supersymmetric SU(N) and U(N) Chern-Simons-matter theories, with matter superfields in the fundamental representation of SU(N) or U(N). In the l…
Dualities and Phases of 3D N=1 SQCD
Changha Choi, Martin Rocek, Adar Sharon
We study gauge theories with N=1 supersymmetry in 2+1 dimensions. We start by calculating the 1-loop effective superpotential for matter in an arbitrary representation. We then res…
Dualities and the F-Theorem
Adar Sharon
There has recently been a surge of new ideas and results for 2+1 dimensional gauge theories. We consider a recently proposed duality for 2+1 dimensional QCD, which predicts a symme…
Phases of Theories in 2+1 Dimensions
Vladimir Bashmakov, Jaume Gomis, Zohar Komargodski +1
We study the dynamics of 2+1 dimensional theories with supersymmetry. In these theories the supersymmetric ground states behave discontinuously at co-dimension one wal…
Charged Boundary States in the Schwinger Model
Adar Sharon, Gilad Weiss
QED in 1+1 dimensions possesses two rare and interesting properties - It is both exactly solvable and confining. The combination of these two properties makes it the perfect candid…
Comments on Abelian Higgs Models and Persistent Order
Zohar Komargodski, Adar Sharon, Ryan Thorngren +1
A natural question about Quantum Field Theory is whether there is a deformation to a trivial gapped phase. If the underlying theory has an anomaly, then symmetric deformations can…
