Isotopic variations and Zeeman-like splitting in the spectra of nonlinear photonic meta-atoms
S. Zhang, I. Babushkin, U. Morgner +2
We study photonic meta-atoms, a unique class of composite solitary wave, supported in nonlinear waveguides. We establish an analogy to one-dimensional soft-core atoms, allowing to…

Universal properties of locally generated terahertz waveforms from polarization-controlled two- and multi-color ionizing fields
H. Alirezaee, S. Skupin, V. Vaicaitis +4
The polarization states of terahertz (THz) radiation generated in a photo-ionized gas driven by strong two- or multi-frequency fields with locally controlled polarization are studi…
