Emerging exceptional point with breakdown of skin effect in non-Hermitian systems
Sayan Jana, Lea Sirota
We study the interplay of two distinct non-Hermitian parameters: directional coupling and onsite gain-loss, together with topology, in coupled one-dimensional (1D) non-Hermitian Su…
Active Control Approach to Temporal Acoustic Cloaking
Or Lasri, Lea Sirota
We propose a realization of a transformation-based acoustic temporal cloak using an active closed-loop control approach to an equivalent electromagnetic problem. Unlike the more co…
Real-time-controlled artificial quiet channel for acoustic cloaking under varying detection conditions
Or Lasri, Lea Sirota
We consider the problem of hiding non-stationary objects from acoustic detection in a two-dimensional environment, where both the object's impedance and the properties of the detec…
Gravitational lensing and tunneling of mechanical waves in synthetic curved spacetime
Sayan Jana, Lea Sirota
Black holes are considered among the most fascinating objects that exist in our universe, since in the classical formalism nothing, even no light, can escape from their vicinity du…
Temporal negative refraction
Or Lasri, Lea Sirota
Negative refraction is a peculiar wave propagation phenomenon that occurs when a wave crosses a boundary between a regular medium and a medium with both constitutive parameters neg…
Klein-like tunneling of sound via negative index metamaterials
Lea Sirota
Klein tunneling is a counterintuitive quantum-mechanical phenomenon, predicting perfect transmission of relativistic particles through higher energy barriers. This phenomenon was s…
Real-Time Steering of Curved Sound Beams in a Feedback-based Topological Acoustic Metamaterial
Lea Sirota, Daniel Sabsovich, Yoav Lahini +2
We present the concept of a feedback-based topological acoustic metamaterial as a tool for realizing autonomous and active guiding of sound beams along arbitrary curved paths in fr…
Non-Newtonian Topological Mechanical Metamaterials Using Feedback Control
Lea Sirota, Roni Ilan, Yair Shokef +1
We introduce a method to design topological mechanical metamaterials that are not constrained by Newtonian dynamics. The unit cells in a mechanical lattice are subjected to active…
