A nonreciprocal and tunable active acoustic scatterer
Anis Maddi, Gaelle Poignand, Vassos Achilleos +2
A passive loudspeaker mounted in a duct acts as a reciprocal scatterer for plane waves impinging on either of its sides. However, the reciprocity can be broken by means of an asymm…
Envelope vector solitons in nonlinear flexible mechanical metamaterials
Antoine Demiquel, Vassos Achilleos, Georgios Theocharis +1
In this paper, we employ a combination of analytical and numerical techniques to investigate the dynamics of lattice envelope vector soliton solutions propagating within a one-dime…
Robustness of perfect transmission resonances to asymmetric perturbation
Ioannis Kiorpelidis, Panayotis Kalozoumis, Georgios Theocharis +3
We investigate the impact of asymmetric perturbations on the perfect transmission resonances (PTRs) of one-dimensional finite periodic systems. With no perturbations, the scatterin…
Insensitive edge solitons in a non-Hermitian topological lattice
Bertin Many Manda, Vassos Achilleos
In this work, we demonstrate that the synergetic interplay of topology, nonreciprocity and nonlinearity is capable of unprecedented effects. We focus on a nonreciprocal variant of…
