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…

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…
