Achiral nanostructures: perturbative harmonic generation and dichroism under vortex and vector beams illumination
Anastasia Nikitina, Kristina Frizyuk
In this study, we investigate the nonlinear optical phenomena emerging from the interaction of vortex and vector beams with achiral nanoparticles or nanostructures. We reveal the c…
Exceptional points in single open acoustic resonator due to the symmetry breaking
Vladimir Igoshin, Mariia Tsimokha, Anastasia Nikitina +3
Exceptional points (EPs) have been widely studied in quantum mechanics, condensed matter physics, optics and photonics. However, their potential in acoustics has only recently been…
When does nonlinear circular dichroism appear in achiral dielectric nanoparticles?
Anastasia Nikitina, Anna Nikolaeva, Kristina Frizyuk
Sometimes it appears, sometimes it does not. We present a theoretical study of circular dichroism in the second-harmonic signal of single dielectric nanostructures with different s…
