A Mathematical Theory of Quantum Sheaf Cohomology
, 2011 The purpose of this paper is to present a mathematical theory of the half-twisted $(0,2)$ gauged linear sigma model and its correlation functions that agrees with and extends results from physics.

Earthquake Productivity Law in a Wide Magnitude Range
Frontiers in Earth Science, 2022 Earthquakes are usually followed by aftershocks. The number of aftershocks—the so-called productivity—depends on the magnitude of the earthquake. In seismic modeling it is usually assumed that the number of aftershocks is approximately the same for ...

Noninvertible symmetries and anomalies from gauging 1-form electric centers
Journal of High Energy PhysicsWe devise a general method for obtaining 0-form noninvertible discrete chiral symmetries in 4-dimensional SU(N)/ℤ p and SU(N) × U(1)/ℤ p gauge theories with matter in arbitrary representations, where ℤ p is a subgroup of the electric 1-form center ...

Holographic Abrikosov lattices
Journal of High Energy Physics, 2020 We study black hole solutions of D = 4 Einstein-Maxwell theory coupled to a charged scalar field that are holographically dual to a d = 3 conformal field theory with a non-vanishing chemical potential and constant magnetic field. We numerically construct

Formalizing Mathematical Knowledge as a Biform Theory Graph: A Case Study
, 2017 A biform theory is a combination of an axiomatic theory and an algorithmic theory that supports the integration of reasoning and computation. These are ideal for formalizing algorithms that manipulate mathematical expressions. A theory graph is a network
