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…
Supersonic wave propagation in active non-Hermitian acoustic metamaterials
Kangkang Wang, Felix Langfeldt, Chen Shen +4
Obtaining a group velocity higher than the speed of sound in a waveguide is a challenging task in acoustic wave engineering. Even more challenging is to achieve this velocity incre…
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…
Noise avalanche and its quantum quenching in bosonic chains with random off-diagonal disorder
Vladislav Stefanov, Andre Stefanov, Lea Sirota +2
Here we discuss a phenomenon of sharp increase in the photon number noise at initial stages of propagation in tight-binding bosonic chains with off-diagonal disorder. Such a "noise…
Controlled fast wavepackets in non-Hermitian lattices
Yehonatan Benisty, Sayan Jana, Lea Sirota
We report the propagation of fast wavepackets in classical non-Hermitian lattices, where the group velocity is controlled by the non-Hermiticity parameters, and can be made higher…
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…
