In this talk\, I will present an extension of cutof f AdS3 holography that is valid for positive values of the deformation par ameter. In this case\, turning on the deformation parameter brings the asy mptotic boundary of AdS3 to a finite cutoff in an auxiliary AdS3 spacetime . I will show that the theory living at the cutoff surface reproduces many features of TTbar-deformed CFTs with a positive deformation parameter. Fu rthermore\, I will give a geometric prescription for computing the hologra phic entanglement entropy of an interval at the cutoff surface. The hologr aphic entanglement entropy is finite and features a minimum length scale\, as expected for TTbar-deformed CFTs.\n LOCATION:https://researchseminars.org/talk/integrability2022/1/ END:VEVENT BEGIN:VEVENT SUMMARY:Minkyoo Kim (Sogang University) DTSTART:20221031T080000Z DTEND:20221031T084000Z DTSTAMP:20260422T212749Z UID:integrability2022/2 DESCRIPTION:Title: Comments on Heavy Operators in N=4 SYM\nby Minkyoo Kim (Soga ng University) as part of Integrability\, Duality and related topics\n\n\n Abstract\nFor N=4 SYM in the planar limit\, its spectrum is completely sol ved at finite coupling through integrability.  The dynamics of single-tra ce operators and worldsheet formulation of holographic dual strings are su ch cases.  On the other hand\, the spectrum of heavy operators\, which is a holographic dual to giant graviton D-branes\, cannot be restricted to t he planar limit and therefore is not generally integrable.  In this talk\ , I would like to introduce techniques that have been developed to achieve analytic results in these situations.  In particular\, I shall review so me established ideas based on group representation theory and comment on s ome new results.\n LOCATION:https://researchseminars.org/talk/integrability2022/2/ END:VEVENT BEGIN:VEVENT SUMMARY:Luis Apolo (University of Amsterdam) DTSTART:20221031T050000Z DTEND:20221031T060000Z DTSTAMP:20260422T212749Z UID:integrability2022/4 DESCRIPTION:Title: TTbar in string theory\nby Luis Apolo (University of Amsterd am) as part of Integrability\, Duality and related topics\n\nAbstract: TBA \n LOCATION:https://researchseminars.org/talk/integrability2022/4/ END:VEVENT BEGIN:VEVENT SUMMARY:James Bonifacio (University of Cambridge) DTSTART:20221105T003000Z DTEND:20221105T011000Z DTSTAMP:20260422T212749Z UID:integrability2022/5 DESCRIPTION:Title: Bootstrap bounds for hyperbolic manifolds\nby James Bonifaci o (University of Cambridge) as part of Integrability\, Duality and related topics\n\n\nAbstract\nI will discuss how bootstrap methods can be used to derive bounds on the eigenvalues of the Laplace-Beltrami operator on clos ed hyperbolic manifolds.

The poster child of these is the celeb rated “TTbar deformation”. They display unusual properties in the UV\, which can be described exactly\, their irrelevant nature notwithstanding. For this reason they represent a sensible extension of Quantum Field Theo ry beyond the Wilsonian paradigm and have attracted a considerable attenti on from the high energy theory community. The property of being solvable i s shared with a wider class of deformations\, constructed out of pairs of conserved currents. In general these are marginal deformations\, thus pres enting very different UV properties. Nonetheless their structures are simi lar to the TTbar ones\, hinting at the existence of a universal descriptio n.\n\nIn this talk I will present a very general framework that accommodat es both solvable irrelevant and solvable marginal deformations\, which amo unts to a “topological gauging” of the symmetries of the system. Throu gh simple path integral computations\, I will recover the main features of these theories and show their equivalence to TST and Yang-Baxter deformat ions. For the case of TTbar\, the topological gauging perspective explains the previously not understood relation to field theory in non-commutative Minkowski space-time and to the centrally extended Poincaré algebra.\n LOCATION:https://researchseminars.org/talk/integrability2022/7/ END:VEVENT BEGIN:VEVENT SUMMARY:Christian Ferko (UC Davis) DTSTART:20221101T070000Z DTEND:20221101T074000Z DTSTAMP:20260422T212749Z UID:integrability2022/8 DESCRIPTION:Title: Root-TT Deformations\nby Christian Ferko (UC Davis) as part of Integrability\, Duality and related topics\n\n\nAbstract\nIn this talk I will discuss a new proposal for a classically marginal deformation of an y two-dimensional quantum field theory which is constructed from the stres s-energy tensor.

Z. Imbrie (University of Virginia) as part of Integrability\, Dual ity and related topics\n\n\nAbstract\nA quantum system is said to be many- body localized (MBL) if one can find a complete set of local integrals of motion (LIOMs). This leads to a breakdown of thermalization. I will summar ize a proof that certain one-dimensional spin chains have an MBL phase (th e proof depends on a certain assumption on level statistics). In recent wo rk with Morningstar and Huse\, we develop specific RG flow equations to st udy the critical phenomenon at the edge of the MBL phase. This turns out to be similar to the Kosterlitz-Thouless (KT) flow\, but there are importa nt differences that place the MBL transition in a new universality class.\ n LOCATION:https://researchseminars.org/talk/integrability2022/11/ END:VEVENT BEGIN:VEVENT SUMMARY:Max A.

Metlitski (MIT) as part of Integrability\, Duality and related topics\n\n\nAbstract\nIt is known that the classical O(N) model in dimensi on d > 3 at its bulk critical point admits three boundary universality cla sses: the ordinary\, the extraordinary and the special. The extraordinary fixed point corresponds to the bulk transition occurring in the presence o f an ordered boundary\, while the special fixed point corresponds to a bou ndary phase transition between the ordinary and the extra-ordinary classes . While the ordinary fixed point survives in d = 3\, it is less clear what happens to the extraordinary and special fixed points when d = 3 and N is greater or equal to 2. I'll show that formally treating N as a continuous parameter\, there exists a critical value Nc > 2 separating two distinct regimes. For N < Nc the extra-ordinary fixed point survives in d = 3\, alb eit in a modified form: the long-range boundary order is lost\, instead\, the order parameter correlation function decays as a power of log r. For N > Nc there is no fixed point with order parameter correlations decaying slower than power law. I'll discuss how these findings compare to recent M onte-Carlo studies of classical and quantum spin models with SO(3) symmetr y.\n LOCATION:https://researchseminars.org/talk/integrability2022/12/ END:VEVENT BEGIN:VEVENT SUMMARY:Balazs Pozsgay (Eötvös Loránd University) DTSTART:20221102T070000Z DTEND:20221102T074000Z DTSTAMP:20260422T212749Z UID:integrability2022/13 DESCRIPTION:Title: Medium range spin chains -- Algebraic theory\nby Balazs Poz sgay (Eötvös Loránd University) as part of Integrability\, Duality and related topics\n\n\nAbstract\nMost spin chains that are studied have neare st neighbour interactions.

The most fundamental operators in these theor ies are mesonic line operators\, the simplest example being Wilson lines e nding on fundamentals. We classify the conformal line operators along an a rbitrary smooth path as well as the spectrum of conformal dimensions and t ransverse spins of their boundary operators at finite 't Hooft coupling. T hese line operators are shown to satisfy first-order chiral evolution equa tions\, in which a smooth variation of the path is given by a factorized p roduct of two line operators. We argue that this equation\, together with the spectrum of boundary operators\, are sufficient to uniquely determine the expectation values of these operators. We demonstrate this by bootstra pping the two-point function of the displacement operator on a straight li ne. We show that the line operators in the theory of bosons and the theory of fermions satisfy the same evolution equation and have the same spectru m of boundary operators.\n LOCATION:https://researchseminars.org/talk/integrability2022/14/ END:VEVENT BEGIN:VEVENT SUMMARY:Balazs Pozsgay (Eötvös Loránd University) DTSTART:20221102T050000Z DTEND:20221102T060000Z DTSTAMP:20260422T212749Z UID:integrability2022/15 DESCRIPTION:Title: Medium range spin chains -- Motivations: The folded XXZ model\nby Balazs Pozsgay (Eötvös Loránd University) as part of Integrabili ty\, Duality and related topics\n\n\nAbstract\nMost spin chains that are s tudied have nearest neighbour interactions.

For the Ising model with \n$c_{IR} = \\tfrac{1}{2}$ we find 3 UV completions based on a single massless Majorana fermion description with \n$c_{UV} = \\tfrac{7}{10}$ and $ \\tfrac{3}{2}$\, which both have $ N=1$ SUSY and were previously known\, and we argue that these are the onl y solutions to our classification problem based on this spectrum of partic les.

We argue that it is likely there are more cases for this $E_8$ spectrum. \nWe also study simpler cases based on $\\suthree$ and $\\sufour$ where we can propose complete classifications.

Recent progress has focused on supersymmetric black holes in asymptotically AdS s pacetimes in which the sum over classical BPS solutions reproduces the sup erconformal index of the dual CFT. In a parallel line of development\, it has been understood that certain models of 2d gravity describe the near ho rizon region of a near-extremal black hole. At strong coupling the integra l over metrics in these models may be done exactly\, and the solution reve als a coarse-grained chaotic spectrum with no sharply defined microstates.  In this talk\, we will show that these two approaches are compatible an d compute the low-temperature partition function of near-BPS black holes v ia a gravitational path integral. Our approach uses an effective field the ory of the near horizon geometry which reduces to an exactly solvable supe rsymmetric extension of the Schwarzian theory found in toy models of 2d gr avity. The quantization of this theory gives a quantum gravitational deriv ation of the extremal entropy and the superconformal index\, showing that supergravity at strong coupling may exhibit both exact integrable microsta tes as well as a chaotic spectrum of near-BPS states.
