An Index Formula for Supersymmetric Quantum Mechanics

We derive a localization formula for the refined index of gauged quantum mechanics with four supercharges. Our answer takes the form of a residue int…

In this section we study connected correlators of Wilson loops in the zero instanton sector of the two-dimensional Yang-Mills on a two-sphere. Two-dimensional Yang-Mills theory is a well-known and explicitly solvable theory [[36], [37], [38], [39], …

Notes on supersymmetric Wilson loops on a two-sphere

We study a recently discovered family of 1/8-BPS supersymmetric Wilson loops in N=4 super Yang-Mills theory and their string theory duals. The operat…

The Ryu-Takayanagi Formula from Quantum Error Correction

I argue that a version of the quantum-corrected Ryu-Takayanagi formula holds in any quantum error-correcting code. I present this result as a series …

In this paper, we have introduced what we call the minimal modal interpretation of quantum theory. Our interpretation consists of several parsimonious ingredients:

The Minimal Modal Interpretation of Quantum Theory

We introduce a realist, unextravagant interpretation of quantum theory that builds on the existing physical structure of the theory and allows experi…

Removing phase-space restrictions in factorized cross sections

Factorization in gauge theories holds at the amplitude or amplitude-squared level for states of given soft or collinear momenta. When performing phas…

Disentangling Clustering Effects in Jet Algorithms

Clustering algorithms build jets though the iterative application of single particle and pairwise metrics. This leads to phase space constraints that…
