Statistical Design of Chaotic Waveforms with Enhanced Targeting Capabilities
Huanan Li, Suwun Suwunnarat, Tsampikos Kottos
We develop a statistical theory of waveform shaping of incident waves that aim to efficiently deliver energy at weakly lossy targets which are embedded inside chaotic enclosures. O…
Floquet Protocols of Adiabatic State-Flips and Re-Allocation of Exceptional Points
Dashiell Halpern, Huanan Li, Tsampikos Kottos
We introduce the notion of adiabatic state-flip of a Floquet Hamiltonian associated with a non-Hermitian system that it is subjected to two driving schemes with clear separation of…
Towards a Floquet-Network Theory of Non-Reciprocal Transport
Huanan Li, Tsampikos Kottos, Boris Shapiro
We develop a theoretical framework that lays out the fundamental rules under which a periodic (Floquet) driving scheme can induce non-reciprocal transport. Our approach utilizes an…
Frozen Mode Regime in Finite Periodic Structures
Huanan Li, Ilya Vitebskiy, Tsampikos Kottos
Periodic structures with Bloch dispersion relation supporting a stationary inflection point (SIP) can display a unique scattering feature, the frozen mode regime (FMR). The FMR is…
Driving-induced metamorphosis of transport in arrays of coupled resonators
Huanan Li, Tsampikos Kottos, Boris Shapiro
We propose a new driving scheme, when different parts of a system are driven with different, generally incommensurate, frequencies. Such driving provides a flexible handle to contr…
Random Matrix Theory Approach to Chaotic Coherent Perfect Absorbers
Huanan Li, Suwun Suwunnarat, Ragnar Fleischmann +2
We employ Random Matrix Theory in order to investigate coherent perfect absorption (CPA) in lossy systems with complex internal dynamics. The loss strength and energy…
