On-shell action and Entanglement entropy of T$\bar{\text{T}}$-deformed Holographic CFTs

Abstract In this work, we study the holographic dual of the \ttbar deformation following the mixed boundary condition proposal. We point out that a boundary term should be included in the gravity

Decoding stringy near-supersymmetric black holes | BIMSA-Tsinghua String Seminar

Abstract Building on the recent discovery of the first candidate black hole operator in N = 4 super-Yang-Mills, we explore the near-supersymmetric aspects of the theory that capture lightly excited

Timelike Entanglement Entropy | Geometry and Physics Seminar

Abstract Based on spacetime emergence from quantum entanglement, a new complex-valued quantum information measure will be introduced. This quantity will be defined through either the Wick rotation

Form factor bootstrap and TTbar-deformed EE for IQFT | Joint HEP-TH Seminar

Abstract In IQFT, a standard approach to compute correlation functions is the form factor bootstrap. The form factors satisfy some axioms, which can help us solve the form factors. Recently, this

Einstein metrics on spheres of even dimension | BIMSA-BIT Differential Geometry Seminar

Abstract The first non-round Einstein metrics on spheres were described in 1973 by Jensen in dimensions 4n+3 (n >0). For the next 25 years it remained an open problem whether the same could be done...

On the universal behavior of TTbar-deformed CFTs | Joint HEP-TH Seminar

Abstract The torus partition function of TTbar-deformed CFTs is modular invariant. Using this fact, it is shown that TTbar-deformed CFTs exhibit a universal free energy in the high temperature limi...

Space curves and solitons of the KP hierarchy | Topics in Integrability

Abstract It is well known that algebro-geometric solutions of the KdV hierarchy are constructed from the Riemann theta (or Klein sigma) functions associated with hyperelliptic curves, and soliton

YMSC Topology Seminar | String topology, cyclic homology, and the Fukaya A-infinity algebra

Abstract  This talk is devoted to giving a formulation of Lagrangian Floer theory in terms of chain level string topology, which realizes a proposal of K. Fukaya. First, I will describe a new chain

Birational Geometry Workshop

Birational Geometry Workshop This workshop is devoted to an in-depth study of the recent work "Singularities on Fano fibrations and beyond" by Caucher Birkar. This work establishes several
