VENUE: Ramanujan Lecture Hall, ICTS Bengaluru

In recent years, the AdS/CFT correspondence has led to a paradigm shift in the quest for a theory of quantum gravity. In this new approach, spacetime and gravity are viewed not as fundamental, but as emergent descriptions of the dynamics of quantum information in an underlying, microscopic quantum system. The resulting theory has led to a novel confluence between two different subjects, namely general relativity and quantum information theory. This confluence has enriched both the subjects. On the one hand, tools from quantum information theory such as quantum error correction have led to ground-breaking progress on long-standing problems in quantum gravity such as the black hole information paradox. On the other hand, black hole physics has led to fundamental insights on information scrambling in chaotic quantum systems.

Quantum information theory has also provided a new window into the rich world of quantum field theories and many-body dynamics. Fundamental inequalities governing the structure of quantum information have led to novel proofs of known constraints on QFTs such as the c-theorem and the averaged null energy condition, as well as to previously unknown constraints such as the quantum null energy condition. In the world of many-body quantum systems, entanglement structure has provided a robust characterization of phases of quantum matter.

This program seeks to bring together leading experts working at the intersection of quantum gravity, quantum information theory and many-body physics in the hope of ushering in a new wave of progress in this multidisciplinary field. The program will focus on the following broad themes:

- Quantum error correction, the emergence of spacetime, and the black hole interior
- Complexity growth and saturation and its manifestation in gravity
- Multiparty entanglement and its role in holography
- The importance of gravitational constraints in the localization of quantum information.
- Tensor network models in condensed matter and quantum gravity

Prof. Tadashi Takayanagi will be delivering three Infosys-ICTS Chandrasekhar lectures as part of this meeting.

$Yudovich Theory for Rough path Perturbations of Euler’s Equation (Lecture 5) by Torstein Nilssen Program : Deterministic and Stochastic Analysis of Euler and Navier-Stokes Equations ORGANIZERS : Ujjwal Koley (TIFR-CAM Bengaluru, India) and Debayan Maity (TIFR-CAM Bengaluru, India) DATE : 23 September 2024 to 04 October 2024 VENUE : Ramanujan Lecture Hall, ICTS Bengaluru All physical phenomena in areas such as physics, engineering, finance, and biology are inherently nonlinear and therefore described via models of nonlinear partial differential equations (PDEs). The Navier-Stokes and the Euler equations are thought to be the fundamental set of equations governing the motion of fluid flow. Recently, the research area related to fluid flow equations has witnessed multiple seminal new results and groundbreaking techniques. The main aim of the program is to bring in leading researchers from the field of fluid mechanics for an active discussion on these new techniques and exchange of ideas. In his celebrated 1949 paper on statistical hydrodynamics Lars Onsager conjectured that the threshold regularity for the validity of energy conservation of weak solutions to Euler equations is the exponent 1/3. In particular he announced that for larger Hölder exponents any weak solution would conserve the energy, whereas for any smaller exponent there are solutions which do not conserve energy. The first proof of the later part of Onsager conjecture in a Hölder space was given by De Lellis and Szekelyhidi Jr. On the other hand, the existence of infinitely many weak solutions of the Navier-Stokes equations was provided by Buckmaster and Vicol. Furthermore, these techniques were extended by several authors to produce results for stochastic fluid flow equations. Some of the important topics we wish to cover in this workshop includes full resolution of Onsager conjecture, intermittent construction for Navier-Stokes equations, H^{1/2} weak solutions of the incompressible 3D Euler equations, and stochastic convex integration method. Eligibility criteria: PhD students, postdocs, and faculty members are all eligible to apply. Researchers working on the mathematical aspects of fluid flow equations will be given preference.
