Machine-Learning Search for Lax Connections
Osamu Fukushima, Tomohiro Shigemura, Ryosuke Suda +2
We apply a machine learning framework to search for Lax connections in two-dimensional non-linear sigma models using local current data. For the principal chiral model and…
States and IR divergences in factorization algebras
Masashi Kawahira, Tomohiro Shigemura
In field theory, one can consider a variety of states. Within the framework of factorization algebras, one typically works with the natural augmentation state $\langle-\rangle_{\rm…
Scaling law for membrane lifetime
Osamu Fukushima, Tomohiro Shigemura, Kentaroh Yoshida
Membrane configurations in the Banks-Fischler-Shenker-Susskind matrix model are unstable due to the existence of flat directions in the potential and the decay process can be seen…
Heat and work in black hole thermodynamics via holography
Tomohiro Shigemura, Keito Shimizu, Sotaro Sugishita +2
We propose a formulation of black hole thermodynamics that incorporates the notions of heat and work, based on the thermodynamics in quantum theory and the AdS/CFT correspondence.…
