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…
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.…
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…
