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...

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...

Critical points of classical second-order phase transitions are thermodynamic phenomena of particular interest, driven by thermal fluctuations and characterized by emergent scale invariance and universal power-law correlations. At zero temperature...

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...

I will discuss new universal bounds on the spectra of two-dimensional unitary, compact conformal field theories coming from the modular bootstrap. In the presence of a twist gap amongst the Virasoro primary operators (where twist is defined as the...

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...

I will start by reviewing the three inequivalent topological twists of N = 4 SYM on arbitrary four-manifolds and briefly discuss the resulting topological QFTs. I will emphasise the role played by global anomalies of N = 4 in our story and the...
