Exploring the Membrane Theory of Entanglement Dynamics
Márk Mezei, Julio Virrueta
Recently an effective membrane theory valid in a "hydrodynamic limit" was proposed to describe entanglement dynamics of chaotic systems based on results in random quantum circuits…
Exact four point function for large SYK from Regge theory
Changha Choi, Márk Mezei, Gábor Sárosi
Motivated by the goal of understanding quantum systems away from maximal chaos, in this note we derive a simple closed form expression for the fermion four point function of the la…
Bit Threads and the Membrane Theory of Entanglement Dynamics
Cesar A. Agón, Márk Mezei
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…
Solving a family of -like theories
Bruno Le Floch, Márk Mezei
We deform two-dimensional quantum field theories by antisymmetric combinations of their conserved currents that generalize Smirnov and Zamolodchikov's deformation. We ob…
