Asymmetric high-harmonic generation from subwavelength bianisotropic resonators
Albert Mathew, Piyush Jangid, Rebecca Aschwanden +3
High-harmonic generation (HHG) enables attosecond light pulses and table-top sources of coherent extreme-ultraviolet and soft X-ray radiation. Although HHG has long been associated…
Chiral high-harmonic generation in metasurfaces
Piyush Jangid, Maria Antonietta Vincenti, Luca Carletti +3
High-harmonic generation (HHG) provides the only source of attosecond pulses -- currently the shortest accessible time intervals, and it is employed as the only table-top source of…
Nonreciprocal metasurfaces with epsilon-near-zero materials
Albert Mathew, Rebecca Aschwanden, Aditya Tripathi +4
Nonreciprocal optics enables asymmetric transmission of light when its sources and detectors are exchanged. A canonical example -- optical isolator -- enables light propagation in…
Spectral tuning of high-harmonic generation with resonance-gradient metasurfaces
Piyush Jangid, Felix Ulrich Richter, Ming Lun Tseng +4
High-index dielectric subwavelength structures and metasurfaces are capable of enhancing light-matter interaction by orders of magnitude via geometry-dependent optical resonances.…
Dynamical tunnelling of a Nano-mechanical Oscillator
Piyush Jangid, Anil Kumar Chauhan, Sebastian Wüster
The study of the quantum to classical transition is of fundamental as well as technological importance, and focusses on mesoscopic devices, with a size for which either classical p…
