Temporal Parity-Time Symmetry for Extreme Energy Transformations
Huanan Li, Shixiong Yin, Emanuele Galiffi +1
Temporal interfaces introduced by abrupt switching of the constitutive parameters of unbounded media enable unusual wave phenomena. So far, their explorations have been mostly limi…
Active Nonlocal Metasurfaces
Stephanie C. Malek, Adam C. Overvig, Sajan Shrestha +1
Actively tunable and reconfigurable wavefront shaping by optical metasurfaces poses a significant technical challenge often requiring unconventional materials engineering and nanof…
Observation of topological polaritons and photonic magic angles in twisted van der Waals bi-layers
Guangwei Hu, Qingdong Ou, Guangyuan Si +9
Twisted two-dimensional bi-layers offer exquisite control on the electronic bandstructure through the interlayer rotation and coupling, enabling magic-angle flat-band superconducti…
Virtual Critical Coupling
Younes Radi, Alex Krasnok, Andrea Alú
Electromagnetic resonators are a versatile platform to harvest, filter and trap electromagnetic energy, at the basis of many applications from microwaves to optics. Resonators with…
Optomechanically Induced Birefringence and Faraday Effect
Robert Duggan, Javier del Pino, Ewold Verhagen +1
We demonstrate an optomechanical platform where optical mode conversion mediated by mechanical motion enables arbitrary tailoring of polarization states of propagating light fields…
