Optimal Targeted Mode Transport in Complex Wave Environments: A Universal Statistical Framework
Cheng-Zhen Wang, John Guillamon, Ulrich Kuhl +4
Recent advances in the field of structured waves have resulted in sophisticated coherent wavefront shaping schemes that provide unprecedented control of waves in various complex se…
Nonlinearity-induced Scattering Zero Degeneracies for Spectral Management of Coherent Perfect Absorption in Complex Systems
Cheng-Zhen Wang, John Guillamon, William Tuxbury +2
We develop a Coherent Perfect Absorption (CPA) protocol for cases where scale invariance is violated due to the presence of nonlinear mechanisms. We demonstrate, using a microwave…
Bound states in the continuum induced via local symmetries in complex structures
Cheng-Zhen Wang, Ulrich Kuhl, Adin Dowling +2
Bound states in the continuum (BICs) defy conventional wisdom that assumes a spectral separation between propagating waves, that carry energy away, and spatially localized waves co…
Universalities of Asymmetric Transport in Nonlinear Wave Chaotic Systems
Cheng-Zhen Wang, Rodion Kononchuk, Ulrich Kuhl +1
The intrinsic dynamical complexity of classically chaotic systems enforces a universal description of the transport properties of their wave-mechanical analogues. These universal r…
Encircling exceptional points as a non-Hermitian extension of rapid adiabatic passage
Juraj Feilhauer, Alexander Schumer, Jörg Doppler +5
The efficient transfer of excitations between different levels of a quantum system is a task with many applications. Among the various protocols to carry out such a state transfer…
Experimental realization of optimal energy storage in resonators embedded in scattering media
Philipp del Hougne, Rémi Sobry, Olivier Legrand +3
The ability to enhance light-matter interactions by increasing the energy stored in optical resonators is inherently dependent on their coupling to the incident wavefront. In pract…
