Solution of Wave Acceleration and Non-Hermitian Jump in Nonreciprocal Lattices
Sayan Jana, Bertin Many Manda, Vassos Achilleos +2
The time evolution of initially localized wavepackets in the discrete Hatano-Nelson lattice displays a rich dynamical structure shaped by the interplay between dispersion and nonre…

Harnessing Nonlinearity to Tame Wave Dynamics in Nonreciprocal Active Systems
Sayan Jana, Bertin Many Manda, Vassos Achilleos +2
We present a mechanism to generate unidirectional pulse-shaped propagating waves, tamed to exponential growth and dispersion, in active systems with nonreciprocal and nonlinear cou…
