Serre's genus 50 example

This note presents explicit equations (up to birational equivalence over $\mathbb{F}_2$) for a complete, smooth, absolutely irreducible curve $X$ over $\mathbb{F}_2$ of genus $50$ satisfying $#X(\mathbb{F}_2)=40$. Expand abstract.

Covariant Momentum Map Thermodynamics for Parametrized Field Theories

We focus on the case of parametrized first-order field theories, as a concrete simplified model for fully constrained field theories sharing fundamental general covariant features with canonical general relativity. Expand abstract.

Pure and twisted holography

The holography is based on the two-dimensional N=2 supersymmetric Liouville conformal field theory that defines a unitary bulk quantum supergravity theory in three-dimensional anti-de Sitter space. Expand abstract.

Fundamental Physics, the Swampland of Effective Field Theory and Early Universe Cosmology

I will argue that we need to go beyond effective field theory in order to understand the early universe, and that principles of superstring theory will yield a nonsingular cosmology. Expand abstract.

Flat space holography and complex SYK

We derive the boundary action analogous to the Schwarzian as the key link between gravity and field theory sides and show that it coincides with a geometric action discovered recently by one of us, see 1908.08089. Expand abstract.

Monopole operators and their symmetries in QED3-Gross-Neveu models

The quantum critical point (QCP) for this transition is described by a conformal field theory: Compact quantum electrodynamics (QED3) with a fermionic self-interaction, a type of QED3-Gross-Neveu model. Expand abstract.

Type-B Anomaly Matching and the 6D (2,0) Theory

We study type-B conformal anomalies associated with $\frac{1}{2}$-BPS Coulomb-branch operators in 4D $\mathcal N=2$ superconformal field theories. Expand abstract.

A Map Between Primordial Power Spectra and the Effective Field Theory of Inflation

We have developed a precise dictionary between the spectrum of primordial density fluctuations and the parameters of the effective field theory (EFT) of inflation that determine the primordial power spectrum (PPS). Expand abstract.

Unitary quantization of a charged scalar field and Schwinger effect

In this work, we apply the procedure developed for fields in cosmological settings to analyze the quantization of a scalar field in the presence of an external electromagnetic classical field in a flat background. Expand abstract.
