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,…

The Courant-Hilbert construction in 4D Chern-Simons theory

Osamu Fukushima, Takaki Matsumoto, Kentaroh Yoshida

We consider the Courant-Hilbert (CH) construction of integrable deformations of a two-dimensional principal chiral model (2D PCM) in the context of the four-dimensional Chern-Simon…

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…

4D Chern-Simons theory with auxiliary fields

Osamu Fukushima, Kentaroh Yoshida

The auxiliary field sigma model (AFSM) has recently been constructed by Ferko and Smith as deformations of the principal chiral model by including auxiliary fields and the potentia…
