Enstrophy from symmetry and holography
/ Pinzani Fokeeva, Natalia (speaker)
Enstrophy is an approximately conserved quantity in 2+1 dimensional fluid flows that has dramatic consequences for the phenomenology of turbulence: it implies an inverse energy cascade in 2+1 dimensions.
In this talk, I will illustrate an algorithm to construct an enstrophy current for fluid flows with various degrees of symmetry, including, but not limited to, the well-known case of non-relativistic (Galilean) fluid flows.
Moreover, I will identify the accidental symmetry associated with enstrophy conservation in a recently realized effective action for hydrodynamics.
Finally, I will show how horizon symmetries of 3+1 dimensional black holes with Anti-de Sitter asymptotics also lead to enstrophy conservation..

Holographic Entropy Cone from Marginal Independence
/ Hubeny, Veronika (speaker) (UC-Davis)
This talk will explain recent puzzling revelations in the ongoing efforts to obtain a useful characterization of entanglement structure of geometric states in a holographic CFT, via the so-called holographic entropy cone (HEC). The relations between subsystem entanglement entropies which delimit this cone are known explicitly for only a rather coarse subdivision of the system (specified by N spatial regions, for up to N = 5). [...]

Thermalization of 2d Quantum Field Theories
/ Luca, Delacrétaz (speaker) (University of Chicago)
I will show that (1+1)d QFTs typically thermalize more slowly than the expected "Planckian" equilibration time 1/T. This arises due to causality, which imposes strong constraints on the emergence of hydrodynamic sound in low dimensions. [...]

The volume of the black hole interior at late times
/ Sarosi, Gabor (speaker) (CERN)
The volume of the interior of a two-sided eternal black hole classically grows forever. I will show that in JT gravity, summing the non-perturbative contribution of higher topologies leads to a saturation of the volume of the interior at times exponential in the entropy of the black hole. [...]

Complexity and Conformal Transformations
/ Flory, Mario (speaker) (Jagiellonian University)
In this talk I will (mainly) present my recent work on complexity, especially how conformal transformations in AdS_3/CFT_2 can provide useful information to check holographic complexity proposals, as well as considerations of complexity of conformal transformations on the field theory side..
