Nonlinearity-induced topological phase transition characterized by the nonlinear Chern number

K. Sone, M. Ezawa, et al.

This groundbreaking research by Kazuki Sone, Motohiko Ezawa, Yuto Ashida, Nobuyuki Yoshioka, and Takahiro Sagawa reveals a nonlinear Chern number to characterize topological phases in nonlinear systems, uncovering a fascinating bulk-boundary correspondence even in intense nonlinear conditions. Discover how this work opens pathways to explore nonlinear topological materials that were previously disconnected from the linear regime.
