Ballistic metamaterials

open access: yesOptica, 2020
We report the theoretical prediction and experimental realization of the optical phenomenon of “ballistic resonance.” This resonance, resulting from the interplay between free charge motion in confining geometries and periodic driving electromagnetic fields, can be utilized to achieve negative permittivity at frequencies well above the bulk plasma ...

Ballistic Behavior of New Alumina Composites Reinforced with Niobo-Phosphate Glass [PDF]

open access: yesMaterials Research, 2019
This work aimed to produce and evaluate the ballistic behavior of niobo-phosphate glass-doped alumina composites. The niobo-phosphate glass (30% Nb2O5- 30% P2O5- 20% CaO - 20% CaF2, by mol) were added to the alumina in six different weight percentages ...

Multiphoton Quantum Reservoirs For Robust Multidimensional Computing. [PDF]

open access: yesAdv Sci (Weinh)
Projective measurements reveal hidden multidimensional quantum networks within classical multiphoton fields, enabling robust quantum reservoirs for room‐temperature quantum simulation, prediction, and information processing. These networks transform noisy classical photonic platforms into scalable quantum computational architectures.
