A. Castro: Wilson lines and Ishibashi states in AdS_3/CFT_2 Room: 02.430 In this talk I will discuss a refined interpretation of a gravitational Wilson line in AdS_3 in terms of Ishibashi states in the dual CFT_2. Our strategy is to give a method to evaluate the Wilson line that accounts for all the information contained in the representation, and clarify the role of boundary conditions at the endpoints of the line operator. This gives a novel way to explore and reconstruct the local bulk dynamics.

M. Petropoulos: Carrollian fluids and holographic applications Room: 02.430 General-covariant Galilean or Carrollian hydrodynamics can be reached from relativistic fluids observed from either Zermelo or Randers-Papapetrou frames, at infinite or vanishing velocity of light. I will focus on the latter case, display the general equations and describe the paramount role of Carrollian fluids in flat holography: duals of Ricci-flat spacetimes in the sense of fluid/gravity correspondence are Carrollian fluids defined at null infinity. Robinson-Trautman or Kerr-Taub-NUT families illustrate these results.

P. Horvathy: A unified framework for Galilei and Carroll symmetry Room: 02.430 Whereas the usual Wigner-In\"on\"u contraction $c\to\infty$ of the Poincar\'e group yields the Galilei group, another $c\to0$ contraction yields the ``Carroll group" of L\'evy-Leblond. Both boost-invariant theories are conveniently unified within the ``Eisenhart-Duval'' framework. Plane gravitational waves carry a non-trivially implemented Carroll symmetry with broken rotations.

F. Pena-Benitez: Non-Relativistic Scaling in Semimetals Room: 02.430 I will discuss some examples of (condensed matter) systems with point like band touching but anisotropic spatial scaling. Then, I will talk about the recent attempts to describe these type of topologically non-trivial states of matter from holography.

V. Giangreco Puletti: Entanglement entropy in generalised Quantum Lifshitz theories Room: 02.430 In the first part of the talk I will review the so-called generalised quantum Lifshitz theories. These are (d+1)-dimensional field theories with Lifshitz scaling symmetry, which exhibit certain features of d-dimensional conformal theories, whenever the dynamical critical exponent is equal to the number of spatial dimensions. In the second part of the talk, I will outline the computation of entanglement entropy for spherical entangling surfaces in Lifshitz theories in (d+1)-dimensions, and finally, discuss the results.

H. Afshar: Asymptotic Symmetries in p-Form Theories Room: 02.430 We consider (p+1)-form gauge fields in flat (2p+4)-dimensions for which the radiation and the Coulomb solutions have the same asymptotic falloff behavior. Imposing appropriate falloff behavior on fields and adopting a Maxwell-type action, we construct the boundary term which renders the action principle well-defined in the Lorenz gauge. We then compute conserved surface charges and the corresponding asymptotic charge algebra associated with nontrivial gauge transformations. We show that for p≥1 cases we have three sets of conserved asymptotic charges associated with exact, coexact and zero-mode parts of the corresponding p-form gauge transformations on the asymptotic S^{2p+2}. The coexact and zero-mode charges are higher form extensions of the four dimensional electrodynamics case (p=0), and are commuting. Charges associated with exact gauge transformations have no counterparts in four dimensions and form infinite copies of Heisenberg algebras. We briefly discuss physical implications of these charges and their algebra
