Nonlinear Wavepacket Dynamics in Proximity to a Stationary Inflection Point
Serena Landers, Arkady Kurnosov, William Tuxbury +2
A stationary inflection point (SIP) in the Bloch dispersion relation of a periodic waveguide is an exceptional point degeneracy where three Bloch eigenmodes coalesce forming the so…
