Exploring TTbar Deformations, Integrable Models, and String Theory

Conference Overview

The unification of quantum field theory (QFT) and gravity remains a central challenge in theoretical physics, with string theory providing a promising framework for quantum gravity. This endeavor has not only advanced fundamental physics but also spurred transformative developments in puremathematics, mathematical physics, and high-energy theory.

This conference will bring together leading international and Chinese researchers in string theory, integrable systems, and quantum field theory to:

• Exchange cutting-edge ideas on recent breakthroughs and open challenges,

• Strengthen existing collaborations and foster new interdisciplinary partnerships,

• Explore the role of T̄T deformations and integrable models in bridging QFT, gravity, and string theory.

Research Themes

The program will focus on four interconnected themes, highlighting the synergy between theory and observation:

1. Higher-Dimensional Generalizations of T̄T Deformations

   • Extensions of T̄T-like operators beyond two dimensions and their implications for holography and renormalization group flows.

2. Root-T̄T Deformations and Integrable Models

   • Connections between integrability-preserving deformations, solvable lattice models, and their string-theoretic realizations.

3. T̄T Deformations and Entanglement Entropy

   • Non-perturbative effects on quantum information measures, including holographic entanglement entropy and Page curve dynamics.

4. T̄T Flows and Ricci Flow Equations

   • Geometric interpretations of T̄T as a worldsheet flow and links to 2D gravity and random geometry.

Interdisciplinary Impact

These themes have broad applications, including:

• Nonlinear electrodynamics and modified gravity theories,

• Supersymmetric AdS/CFT and black hole microstate physics,

• Two-dimensional CFTs and their deformed counterparts,

• Integrability in AdS/CFT and beyond.

By uniting these perspectives, the conference aims to illuminate new pathways in quantum gravity, non-perturbative QFT, and their mathematical foundations.
