I will discuss recent work that studies the evolution of the von Neumann entropy of a holographic boundary system dual to an evaporating black hole in AdS. This entropy is computed via the Engelhardt-Wall prescription of extremizing the generalized...

We consider supersymmetric $AdS_3\times Y_7$ solutions of type IIB supergravity dual to N=(0,2) SCFTs in d=2, as well as $AdS_2\times Y_9$ solutions of D=11 supergravity dual to N=2 supersymmetric quantum mechanics, some of which arise as the near...

We are experimentally investigating possible violations of the Pauli Exclusion Principle in the cosmic silence of the Gran Sasso underground laboratory in Italy, by hunting "impossible" atomic transitions. I shall present our recent results and...

Our Universe is filled with Cosmic Microwave Background (CMB) radiation having an almost perfect black body spectrum with a temperature of To=2.7K. The number density of photons in our Universe exceeds the number density of electrons by a factor of...

We present recent advances in constructions of globally consistent
F-theory compactifications with the exact chiral spectrum of the minimal
supersymmetric Standard Model. We highlight the first such example and
then turn to a subsequent systematic...

Anomalies are invariants under renormalization group flow which lead to powerful constraints on the phases of quantum field theories. I will explain how these ideas can be generalized to families of theories labelled by coupling constants like the...

The LIGO/VIRGO collaboration has just started their observing run 3. I will first give an introduction to gravitational wave searches and the events that have been found so far and describe some of the interesting astrophysics problems that might be...

My talk will aim to be a friendly introduction for condensed matter friends, mathematicians, and QFT theorists alike --- I shall quickly review and warm up the use of higher symmetries and anomalies of gauge theories and condensed matter systems...

In many-body chaotic systems, the size of an operator generically grows in Heisenberg evolution, and is measured by out-of-time-ordered four-point functions. However, these only provide a coarse probe of the full underlying operator growth structure...

Charge transport near quantum critical points partly occur in phases with spontaneously broken symmetries. In an effective field theory approach, this transport can be described in a hydrodynamic theory with Goldstone modes encoding the broken...
