A gravitational realization of Courant--Hilbert deformations
Osamu Fukushima, Miyabi Kurihara, Takaki Matsumoto +1
Courant--Hilbert (CH) deformations unify broad classes of solvable stress-tensor flows including and root-. However, a gravitational action that systematically…
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…
Courant-Hilbert deformations of Yang-Baxter sigma models
Osamu Fukushima, Takaki Matsumoto, Kentaroh Yoshida
We present integrable deformations of Yang-Baxter (YB) sigma models based on the Courant-Hilbert (CH) construction. To this end, we employ the four-dimensional Chern-Simons theory,…
