Regular Seminar Mauricio Valenzuela (Chile Austral U., Valdivia)
at: 13:15 room S0.13  abstract: The goal of this talk is to show some uses of the GronewoldMoyal product in physics and new applications. In the first part of this talk we review the approach of Gronewold and Moyal in the quantization of classical systems. Then we remark algebraic aspects related to the representation of symplectic algebras and extensions of AntideSitter algebras. Subsequently we describe how these aspects are used in higher spin gravity. In the second part of this talk we present some new advances. We quantize a particular class of algebraic varieties, involving multivectors, and which contains Minkowski space slices. We show that these noncommutative geometries are solutions of known matrix models and some simple extensions of them. Then we present new models which describe the dynamics of extended objects in close resemblance to the equations of Hamiltonian systems. We also introduce statistical distributions in these spaces which encode their coordinates spectra. 
Regular Seminar Benjamin Basso (ENS, Paris)
at: 13:15 room S0.13  abstract: I will present a framework for computing correlators of three single trace operators in planar N=4 SYM theory that uses hexagonal patches as building blocks. This approach allows one to exploit the integrability of the theory and derive all loop predictions for its structure constants. After presenting the main ideas and results, I will discuss recent perturbative tests and open problems. 
Exceptional Seminar Akinori Tanaka (RIKEN, Wako, JAPAN)
at: 13:15 room Norfork G.01  abstract: In 2007, it was conjectured by E.Witten that the chiral part of the partition function of 3d pure AdS Einstein gravity in quantum regime coincides with socalled modular Jfunction, a partition function of certain holomorphic CFT, called "monster CFT" considered by I. B Frenkel, J. Lepowsky and A. Meurman in the context of monstrous moonshine. We tried to calculate the partition function for the 3d pure AdS Einstein gravity directly by utilizing recently developed localization techniques.Based on some plausible assumptions, we arrived at CFT interpretations.For quantum gravity regime which corresponds to c=24, we get Jfunction.For semiclassical regime which corresponds c>>1, our partition function decomposes to Virasoro characters, and we derive Cardy formula. If possible, I will comment on application to quantum higher spin gravity.This talk is based on 1504.05991 and 1510.02142. 
Triangular Seminar Clay Cordova (IAS)

Regular Seminar Francesco Benini (Imperial College)
at: 13:15 room S0.13  abstract: One of the great successes of string theory, as a theory of quantum gravity, is the explanation of the entropy of asymptoticallyflat black holes. I will present, instead, a counting of the microstates of certain black holes in AdS4. The black holes have an holographic description as RG flows from a 3D CFT to superconformal quantum mechanics, and the counting of microstates proceeds via supersymmetric localization. Along the way, we will define and compute an index for topologically twisted theories, and propose an extremization principle to determine the superconformal Rsymmetry in quantum mechanics. 
Regular Seminar Andrew Hickling (Imperial College)
at: 14:15 room S4.23  abstract: Two interesting properties of static curved space QFTs are Casimir Energies, and the Energy Gaps of fluctuations. We investigate what AdS/CFT has to say about these properties by examining holographic CFTs defined on curved but static spatially closed spacetimes. Being holographic, these CFTs have a dual gravitational description under Gauge/Gravity duality, and these properties of the CFT are reflected in the geometry of the dual bulk. We can turn this on its head and ask, what does the existence of the gravitational bulk dual imply about these properties of the CFTs? In this talk we will consider holographic CFTs where the dual vacuum state is described by pure Einstein gravity with negative cosmological constant. We will argue using the bulk geometry first, that if the CFT spacetime's spatial scalar curvature is positive there is a lower bound on the gap for scalar fluctuations, controlled by the minimum value of the boundary Ricci scalar. In fact, we will show that it is precisely the same bound as is satisfied by free scalar CFTs, suggesting that this bound might be something that applies more generally than just in a Holographic context. We will then show, in the case of 2+1 dimensional CFTs, that the Casimir energy is nonpositive, and is in fact negative unless the CFT's scalar curvature is constant. In this case, there is no restriction on the boundary scalar curvature, and we can even allow singularities in the bulk, so long as they are 'good' singularities. If time permits, we will also describe some new results about the HawkingPage transition in this context.

Exceptional Seminar Masahito Yamazaki (IPMU)
at: 13:15 room S6.06  abstract: In this talk I will describe codimension 2 and 4 defects in 6d (2,0) theories in several points of view: 3d SL(N,C) ChernSimons theory (stateintegral model, cluster algebra), 3d N=2 field theory, 5d N=2 super YangMills, and AdS4 holographic dual. This leads to quantitative consistency checks of different approaches, as well as new predictions for a variety of partition functions. 
Regular Seminar Jorge Santos (DAMTP, Cambridge)
at: 13:15 room S.0.13  abstract: We numerically construct asymptotically antide Sitter (AdS) black holes in four dimensions that contain only a single Killing vector field. These solutions, which we coin black resonators, link the superradiant instability of KerrAdS to the nonlinear weakly turbulent instability of AdS by connecting the onset of the superradiance instability to smooth, horizonless geometries called geons. Furthermore, they demonstrate nonuniqueness of KerrAdS by sharing asymptotic charges. Where black resonators coexist with KerrAdS, we find that the black resonators have higher entropy. Nevertheless, we show that black resonators are unstable and comment on the implications for the endpoint of the superradiant instability. 
Regular Seminar Lionel Mason (Oxford University)
at: 13:15 room S0.13  abstract: Ambitwistor strings are holomorphic string theories whose target space is the space of complex null geoedesics in complexified spacetimes. I will explain how these theories explain the origin of the scattering equations in twistor strings and the CHY formulae in arbitrary dimensions and provide a reformulation of standard gauge, gravity and other theories in a holomorphic infinite tension analogue of conventional string theories. I will show how these results extend to 1loop both on a torus and on a nodal Riemann sphere, and perhaps to higher loops. 
Regular Seminar Adi Armoni (Swansea University)
at: 13:15 room S0.13  abstract: In this talk I will consider brane configurations that include NS5 branes, orientifold planes and antibranes. I will argue that the class of field theories that live on such brane configurations admit Seiberg duality. Interactions between branes and orientifold planes will be given a field theory interpretation. In particular a certain repulsive interaction will lead to a nontrivial ColemanWeinberg potential and dynamical symmetry breaking. I will also discuss the case of type 0' strings and chiral symmetry breaking of the form SU(Nf)xSU(Nf)>SU(Nf) in a QCDlike theory. 
Regular Seminar David Tong (DAMTP, Cambridge)
at: 13:15 room S0.13  abstract: There exist, in d=2+1 dimensions, field theories that are supersymmetric but nonrelativistic. I will show that the lowenergy physics of these theories is that of the fractional quantum Hall effect. Supersymmetry provides enough analytic control to explicitly derive the ground state wavefunctions and their excitations. 
Regular Seminar Daisuke Yokoyama (King's College London)
at: 13:15 room S.013  abstract: We study the free energy of the three dimensional N=2 supersymmetric ChernSimonsMatter theory dual to AdS4 times toric seven dimensional SasakiEinstein manifold. Although it is not known in general how to construct the CSM theory from the geometric data of the 7d SE manifold (which is called toric diagram), the free energy in the large N limit may be derived. We present the free energy as a quartic polynomial of trial Rcharges for generic toric diagram with up to 6 vertices, and some particular diagrams with 8 vertices. The free energy reproduces the MartelliSparksYau volume function. 
Informal Seminar Imtak Jeon (KIAS)
at: 13:15 room S.0.13  abstract: We use the techniques of supersymmetric localization to compute the BPS black hole entropy in N=2 supergravity. We focus on the n_v+1 vector multiplets on the black hole near horizon background which is AdS_2 x S^2 space. We find the localizing saddle point of the vector multiplets by solving the localization equations, and compute the exact one loop partition function on the saddle point. Furthermore, we propose the appropriate functional integration measure. Through this measure, the one loop determinant is written in terms of the radius of the physical metric, which depends on the localizing saddle point value of the vector multiplets. The result for the one loop determinant is consistent with the logarithmic corrections to the BPS black hole entropy from vector multiplets.

Exceptional Seminar Babak Haghighat (Harvard)
at: 14:30 room S4.36  abstract: We consider bound states of strings which arise in 6d (1,0) SCFTs that are realized in Ftheory in terms of linear chains of spheres with negative selfintersections 1,2, and 4. These include the strings associated to N small E8 instantons, as well as the ones associated to M5 branes probing A and D type singularities in Mtheory or D5 branes probing ADE singularities in Type IIB string theory. We find that these bound states of strings admit (0,4) supersymmetric quiver descriptions and show how one can compute their elliptic genera. 
Regular Seminar Aalok Misra (Indian Institute of Technology)
at: 13:15 room G.01  abstract: We will discuss the construction of type IIA mirror a la Strominger Yau Zaslow prescription and its Mtheory uplift in the delocalized limit {resulting in black M3branes=asymptotically black M5branes wrapping large integer sum of twospheres in AdS_5xM_6} of type IIB backgrounds involving nonKaehler resolved warped deformed conifolds in the presence of [fractional]D3 and wrapped D7branes relevant to thermal QCD with fundamental quarks. We will show that the local T^3 relevant to SYZ mirror construction obeys the same constraint as the maximal T^2invariant special Lagrangian threecycle of deformed conifolds. We also discuss evaluation of the SU(3) structure torsion classes of the type IIB background and show its (approximate) Kaehlerity. We will also discuss thermodynamical/hydrodynamical properties as well as evaluation of a variety of transport coefficients {from correlation functions of gauge and metric fluctuations}, speed of sound and QCD deconfinement temperature consistent with lattice data. 
Exceptional Seminar Antonio Sciarappa (SISSA (Trieste))
at: 14:15 room K3.11  abstract: Hydrodynamic integrable systems are characterized by an infinite number of conserved quantities and can be described in terms of integrable partial differential equations. I will focus on the periodic Intermediate Long Wave (ILW) system, both at the classical and quantum level. The quantum system has not been solved yet, if not in a particular limit (the BenjaminOno limit) which is related to the AGT correspondence. In this talk I will show how a particular two dimensional N=(2,2) gauge theory on S^2 can be used to determine the spectrum of the quantum ILW system via Bethe Ansatz equations, as well as the norm of the eigenstates. In addition the partition function of this theory computes genus zero GromovWitten invariants for the ADHM instanton moduli space, thus relating quantum cohomology to quantum hydrodynamics.
