de Sitter Vacua & pUniverses
We analyze a simple extension of the Schwinger model, which we refer to as the $p$-Schwinger model, on a de Sitter background. In this …

Medicine show: A Calogero model with principal series states
The textitCalogero model is an interacting, $N$-particle, $\mathfrak{sl}(2,\mathbb{R})$-invariant quantum mechanics, whose Hilbert …

The phases of chaos
We develop a novel physical picture to understand certain universal properties of the GUE matrix model which are typically ascribed to …

De Sitter at all loops: the story of the Schwinger model
We consider the two-dimensional Schwinger model of a massless charged fermion coupled to an Abelian gauge field on a fixed de Sitter …

The discreet charm of the discrete series in dS$_2$
We study quantum field theories placed on a two-dimensional de Sitter spacetime (dS$_2$) with an eye on the group-theoretic …

OPE statistics from higher-point crossing
We present new asymptotic formulas for the distribution of OPE coefficients in conformal field theories. These formulas involve …

A general definition of $JT_a$ - deformed QFTs
We propose a general path-integral definition of two-dimensional quantum field theories deformed by an integrable, irrelevant vector …
