In this talk I discuss Hamiltonian truncation, a toolkit to construct quantum field theories. Hamiltonian truncation is in many ways orthogonal to the more familiar lattice regularization, and it can be used to systematically compute QFT observables...

Many experiments point to a significant transformation in the electronic state of the cuprate superconductors as their density is varied at very low temperature. The critical density is close to the “optimal” density where the superconductivity is...

I will go over the new proof of the quantum null energy condition (QNEC):https://arxiv.org/abs/1812.04683The proof uses tools and techniques from the modular theory. In particular, see Section 2.4 theorem B of Borchers notes:https://www.mat.univie...

Operators with non-integer spin have been considered in the literature in various forms and contexts, and have been suggested to control the Regge limit and the OPE of average null energy operators. I will discuss the idea of formally introducing...

Compact Lie Algebras su(N) have aspects of their representations conveniently expressed in terms of matrices, but they also have some aspect that are most conveniently described by terms of graphical means, i.e. weight spaces, root space, Dynkin...

The quartic coupling of the Standard Model Higgs nearly vanishes at a high energy scale. We show that this is explained by the parity symmetry and its spontaneous break down by the condensation of the parity partner of the Higgs. The parity can...

I will discuss an approach to integrable models from a four-dimensional Chern-Simons-type gauge theory. For introduction please have a look at E. Witten arXiv:1611.00592 or K. Costello arXiv:1308.0370. It might be interesting to look into some...

We study ’’t Hooft anomalies of 1-form and 0-form symmetries in SU(N) gauge theories with adjoint fermions, focusing on the rich worldvolume physics of domain walls mandated by anomaly inflow. In two semiclassical regimes—one of the high-T theory...

I’ll talk about the size-momentum correspondence and use it to study scrambling in a near-extremal charged black hole. It’s based on the paper arXiv:1804.04156v4.
