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…
Fast wave transport in two-dimensional -symmetric lattices
Sayan Jana, Lea Sirota
We present a theoretical investigation of wave dynamics in two-dimensional non-Hermitian -symmetric lattices, where onsite, as well as inter-site control couplings ar…
Realizing non-Hermitian tunneling phenomena using non-reciprocal active acoustic metamaterials
Felix Langfeldt, Joe Tan, Sayan Jana +1
Non-reciprocal systems have been shown to exhibit various interesting wave phenomena, such as the non-Hermitian skin effect, which causes accumulation of modes at boundaries. Recen…
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…
Tunneling-like wave transmission in non-Hermitian lattices with mirrored nonreciprocity
Sayan Jana, Lea Sirota
We report a peculiar tunneling phenomenon that occurs in lattices with nonreciprocal couplings. The nonreciprocity holds for an inner portion of the lattice, constituting a non-Her…
