Schur Connections: Chord Counting, Line Operators, and Indices
Oscar Lewis, Mark Mezei, Matteo Sacchi +1
Recently, an intriguing correspondence was conjectured in arXiv:2409.11551 between Schur half-indices of pure 4d supersymmetric Yang-Mills (SYM) theory with…
Nonlinear soft mode action for the large- SYK model
Marta Bucca, Márk Mezei
The physics of the SYK model at low temperatures is dominated by a soft mode governed by the Schwarzian action. In arXiv:1604.07818 the linearised action was derived from the soft…
Phases of Wilson Lines: Conformality and Screening
Ofer Aharony, Gabriel Cuomo, Zohar Komargodski +2
We study the rich dynamics resulting from introducing static charged particles (Wilson lines) in 2+1 and 3+1 dimensional gauge theories. Depending on the charges of the external pa…
Effective description of sub-maximal chaos: stringy effects for SYK scrambling
Changha Choi, Felix M. Haehl, Márk Mezei +1
It has been proposed that the exponential decay and subsequent power law saturation of out-of-time-order correlation functions can be universally described by collective 'scramblon…
Phases of Wilson Lines in Conformal Field Theories
Ofer Aharony, Gabriel Cuomo, Zohar Komargodski +2
We study the low-energy limit of Wilson lines (charged impurities) in conformal gauge theories in 2+1 and 3+1 dimensions. As a function of the representation of the Wilson line, ce…

We summarize recent progress in the development, application, and understanding of effective field theories and highlight promising directions for future research. This Report is p…
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…
Spin Impurities, Wilson Lines and Semiclassics
Gabriel Cuomo, Zohar Komargodski, Márk Mezei +1
We consider line defects with large quantum numbers in conformal field theories. First, we consider spin impurities, both for a free scalar triplet and in the Wilson-Fisher …
Localized magnetic field in the model
Gabriel Cuomo, Zohar Komargodski, Márk Mezei
We consider the critical model in the presence of an external magnetic field localized in space. This setup can potentially be realized in quantum simulators and in some liq…
Boundary Conformal Field Theory at Large Charge
Gabriel Cuomo, Márk Mezei, Avia Raviv-Moshe
We study operators with large internal charge in boundary conformal field theories (BCFTs) with internal symmetries. Using the state-operator correspondence and the existence of a…
The volume of the black hole interior at late times
Luca V. Iliesiu, Márk Mezei, Gábor Sárosi
Understanding the fate of semi-classical black hole solutions at very late times is one of the most important open questions in quantum gravity. In this paper, we provide a path in…
Spontaneously Broken Boosts in CFTs
Zohar Komargodski, Márk Mezei, Sridip Pal +1
Conformal Field Theories (CFTs) have rich dynamics in heavy states. We describe the constraints due to spontaneously broken boost and dilatation symmetries in such states. The spon…
Pole skipping away from maximal chaos
Changha Choi, Márk Mezei, Gábor Sárosi
Pole skipping is a recently discovered subtle effect in the thermal energy density retarded two point function at a special point in the complex planes. We propose that pol…

Márk Mezei, Wilke van der Schee
There is a simple bound on how fast the entanglement entropy of a subregion of a many-body quantum system can saturate in a quench: , where i…

Recently, an effective {\it membrane theory} was proposed that describes the ``hydrodynamic'' regime of the entanglement dynamics for general chaotic systems. Motivated by the new…
The Quantum Null Energy Condition and Entanglement Entropy in Quenches
Márk Mezei, Julio Virrueta
The Quantum Null Energy Condition (QNEC) relates energy to the second variation of entropy in relativistic quantum field theory. We use the QNEC inequality to bound entanglement en…
Chaos in the butterfly cone
Márk Mezei, Gábor Sárosi
A simple probe of chaos and operator growth in many-body quantum systems is the out of time ordered four point function. In a large class of local systems, the effects of chaos in…
KdV charges in theories and new models with super-Hagedorn behavior
Bruno Le Floch, Márk Mezei
Two-dimensional CFTs and integrable models have an infinite set of conserved KdV higher spin currents. These currents can be argued to remain conserved under the deforma…
