We compute the local second variation of the von Neumann entropy of a region in theories with a gravity dual. For null variations our formula says that the diagonal part of the Quantum Null Energy Condition is saturated in every state, thus...

All of the tree amplitudes are constructed for four supersymmetric theories in six dimensions using spinor-helicity variables and the CHY formalism. Two of the theories, the world volume theories of an M5-brane and a D5-brane, only have nonzero...

Entanglement is an important property of quantum systems, but its precise definition in field theory poses some challenges. The problem is particularly acute in gauge theories and string theory, where extended objects such as Wilson loops and...

Since the discovery of Higgs, particle physics is now face a transition. What is the next step is the major questions to our field. I will discuss an initiative from China: Circular electron-positron Collider and its design and R&D progress. In...

With the recent LIGO results it has been clear that we can learn a lot about the distribution of binary black hole systems. Yet the origin of these black holes is still unknown. Do they come from galactic centers, globular clusters, or from more...

We discuss some target space aspects of the FZZ duality both in the Euclidean setup of the cigar geometry and in the SL(2)/U(1) black hole. We argue that the 2D classical SL(2)/U(1) black hole could shed some light on quantum black holes in higher...

In this talk I review new results obtained for SCFT's in 4 and 5 dimensions by compactifying 6 dimensional (1,0) SCFT's on a circle or on Riemann surfaces.
