Chiral metamaterials with PT symmetry and beyond

Sotiris Droulias, Ioannis Katsantonis, Maria Kafesaki +2

Optical systems with gain and loss that respect Parity-Time (PT) symmetry can have real eigenvalues despite their non-Hermitian character. Chiral systems impose circularly polarize…

Sub-cycle quantum electrodynamics in strongly laser-driven semiconductors

N. Tsatrafyllis, S. Kuhn, M. Dumergue +8

Electrodynamical processes induced in complex systems like semiconductors by strong electromagnetic fields, have traditionally/conventionally been described using semi-classical ap…

Precise amplitude, trajectory, and beam-width control of accelerating and abruptly autofocusing beams

Michael Goutsoulas, Nikolaos K. Efremidis

We show that it is possible to independently control both the trajectory and the maximum amplitude along the trajectory of a paraxial accelerating beam. This is accomplished by car…

Investigation of broadband terahertz generation from metasurface

Ming Fang, Kaikun Niu, Zhiaxiang Huang +4

The nonlinear metamaterials have been shown to provide nonlinear properties with high nonlinear conversion efficiency and in a myriad of light manipulation. Here we study terahertz…

Hyperuniformity in amorphous speckle patterns

Diego Di Battista, Daniele Ancora, Giannis Zacharakis +2

Hyperuniform structures possess the ability to confine and drive light, although their fabrication is extremely challenging. Here we demonstrate that speckle patters obtained by a…
