How are bulk strings related to boundary Feynman diagrams? I will give an overview of my work with Rajesh Gopakumar on deriving the closed string dual to the simplest possible gauge theory,

I will talk about models of two dimensional random growth (namely, polynuclear growth) which can be translated into probability laws on integer partitions by way of the RSK algorithm. As a consequence,

The local information of a 2d rational conformal field theory (RCFT) is encoded in a vertex operator algebra, whose modules constitute a modular fusion category C. The collection of global observables of

Recently, the study of higher categories of topological defects in quantum field theory has gained significant attention due to their connection to categorical symmetries. These higher categories exhibit noteworthy additional structures, depending

Cosmic strings (or vortex strings) are topological defects arising when U(1) symmetry is spontaneously broken in quantum field theories. In three-dimensional relativistic systems, loops of cosmic strings are known to be unstable

Four-dimensional Wess-Zumino-Witten (4dWZW) models are analogous to the two dimensional WZW models and possesses aspects of conformal field theory and twistor theory .  Equation of motion of the 4dWZW model is the

A fundamental prediction of quantum physics is the existence of random fluctuations everywhere in vacuum. This is one of the most remarkable and central ideas in quantum field theory which manifests itself

The prominent role of matrix models in physics and mathematics is well known. It is especially interesting that some of those models are exactly solvable, meaning the one can find explicit formulas

Spin chain are quantum-mechanical models for magnetic materials. Special examples are (quantum) integrable: they have many conserved charges whose spectrum can be determined exactly thanks to a rich underlying algebraic structure. While

Conformal field theory (CFT) plays a crucial role in understanding phase transitions, whether quantum or statistical. Typically, CFTs are studied using perturbative methods, such as the 4-epsilon expansion and the large N

In this presentation, we explore the local exact controllability to a constant trajectory for the compressible Navier-Stokes-Korteweg system on the torus in dimensions $din{1,2,3}$, where the control acts on an open subset.
