Snowmass White Paper: String Theory and Particle Physics / Cvetic, Mirjam (Pennsylvania U. ; Maribor U. ; CERN) ; Halverson, James (Northeastern U. ; IAIFI, Cambridge) ; Shiu, Gary (Wisconsin U., Madison) ; Taylor, Washington (MIT, Cambridge, CTP)
We review recent developments and outstanding questions regarding connecting the top-down UV complete physical framework of string theory with the observed physics of the Standard Model and beyond the Standard Model physics, emphasizing the global nonperturbative framework of F-theory and general lessons from UV physics. [...]

Learning to Unknot / Gukov, Sergei (Caltech, Pasadena (main)) ; Halverson, James (Northeastern U.) ; Ruehle, Fabian (CERN ; Oxford U., Theor. Phys.) ; Sułkowski, Piotr (Caltech, Pasadena (main) ; Warsaw U.)
We introduce natural language processing into the study of knot theory, as made natural by the braid word representation of knots. We study the UNKNOT problem of determining whether or not a given knot is the unknot. [...]

Constraints on Standard Model Constructions in F-theory / Cvetic, Mirjam (Pennsylvania U. ; Maribor U.) ; Halverson, James (Northeastern U.) ; Lin, Ling (CERN) ; Long, Cody (Northeastern U. ; Cornell U., Phys. Dept.)
We argue that the following three statements cannot all be true: (i) our vacuum is a type IIB / F-theory vacuum at moderate-to-large $h^{1,1}$, (ii) the $\alpha'$-expansion is controlled via the supergravity approximation, à la the KKLT and LVS scenarios, and (iii) there are no additional gauged sectors from seven-branes. Since nearly all known globally consistent F-theory models with the exact chiral spectrum of the Standard Model and gauge coupling unification occur at moderate $h^{1,1}$, this finding calls for new moduli stabilization scenarios or/and a rich seven-brane dark sector..

Kähler Moduli Stabilization and the Propagation of Decidability / Halverson, James (Northeastern U.) ; Plesser, Michael (Northeastern U.) ; Ruehle, Fabian (CERN ; Oxford U., Theor. Phys.) ; Tian, Jiahua (Northeastern U.)
Diophantine equations are in general undecidable, yet appear readily in string theory. We demonstrate that numerous classes of Diophantine equations arising in string theory are decidable and propose that decidability may propagate through networks of string vacua due to additional structure in the theory. [...]

Complexity and Random Matrix Approximations / Halverson, James (speaker)
Efforts to better understand the landscape and swampland can be stifled by computational complexity. I will discuss ways in which complexity could be overcome by learning random matrix approximations to string data, including both opportunities and caveats. [...]

Branes with Brains: Exploring String Vacua with Deep Reinforcement Learning / Halverson, James (Northeastern U.) ; Nelson, Brent (Northeastern U.) ; Ruehle, Fabian (CERN ; Oxford U., Theor. Phys.)
We propose deep reinforcement learning as a model-free method for exploring the landscape of string vacua. As a concrete application, we utilize an artificial intelligence agent known as an asynchronous advantage actor-critic to explore type IIA compactifications with intersecting D6-branes. [...]
