Quantum tunneling from excited states in the steadyon picture
Joshua Lin, Bruno Scheihing-Hitschfeld, Thomas Steingasser
Recent developments in the understanding of real-time path integrals led to the development of the ``steadyon picture'' for the semi-classical calculation of quantum tunneling rate…
Path integral predictions for pre-asymptotic false vacuum decay
Joshua Lin, Bruno Scheihing-Hitschfeld, Thomas Steingasser
When tunneling occurs out of generic initial states, a significant fraction of probability is lost at early times during which the dynamics is governed by excited resonance states.…
LenSiam: Self-Supervised Learning on Strong Gravitational Lens Images
Po-Wen Chang, Kuan-Wei Huang, Joshua Fagin +2
Self-supervised learning has been known for learning good representations from data without the need for annotated labels. We explore the simple siamese (SimSiam) architecture for…
An algorithm for computing root multiplicities in Kac-Moody algebras
Aidan Backus, Peter Connick, Joshua Lin
Root multiplicities encode information about the structure of Kac-Moody algebras, and appear in applications as far-reaching as string theory and the theory of modular functions. W…
