Holographic duality is a duality between gravitational systems and non-gravitational systems. In this talk, I will propose a different approach for understanding holographic duality named as the exact holographic mapping. The key idea of this...

I will discuss an interpolation on the Coulomb branch of (1,1) little string theory, from perturbative 6d SYM to double scaled little string theory, by analyzing scattering amplitudes and the related derivative expansion of the Coulomb branch...

While it has been known for some time that charged black branes give rise to Fermi surfaces in AdS/CFT, only recently have enough supergravity calculations been done to start asking systematically when Fermi surfaces occur for the best understood...

We show that in 2d CFTs at large central charge, the coupling of the stress tensor to heavy operators can be re-absorbed by placing the CFT in a non-trivial background metric. This leads to a more precise computation of the Virasoro conformal blocks...

The cusp anomalous dimension is an ubiquitous quantity in four-dimensional gauge theories. It governs the dependence of a cusped Wilson loop on the ultraviolet cut-off and appears in many physical quantities. In particular, it controls the infrared...

Topological Superconductivity is a topic of current interest because of its potential for providing a new method for storing and manipulating quantum information. One of the most basic consequences of topological superconductivity is the fractional...

I will discuss the recent application of the conformal bootstrap program to superconformal field theories (SCFTs) in 3d, focusing on maximally supersymmetric theories. In particular, the constraints from unitarity and crossing symmetry on the 4...

A candidate description for a strange metal phase in 1+1 dimensions,
namely a model of strongly-coupled fermions in the adjoint representation of
SU(N) is considered. It is known that such models at high densities flow
to IR WZNW theories having an...
