Spectral and spatial filtering of whispering gallery modes in precision-engineered microbubble resonators
Ramgopal Madugani, Amal Jose, Christophe Pin +3
Similar to microspheres, thin-walled microbubble resonators support whispering gallery modes (WGMs) that combine ultrahigh Q-factors and small effective mode volumes. In contrast,…
Exceptional-point-controlled mode interaction in three-dimensional microcavities represented by generalized Husimi functions
Tom Rodemund, Shilong Li, Síle Nic Chormaic +1
Non-Hermitian photonics has attracted significant interest and influences several key areas such as optical metamaterials, laser physics, and nonlinear optics. While non-Hermitian…
Complex dynamics in circular and deformed bilayer graphene inspired billiards with anisotropy and strain
Lukas Seemann, Jana Lukin, Max Häßler +2
While billiard systems of various shapes have been used as paradigmatic model systems in the fields of nonlinear dynamics and quantum chaos, few studies have investigated anisotrop…
Steering internal and outgoing electron dynamics in bilayer graphene cavities by cavity design
Lukas Seemann, Angelika Knothe, Martina Hentschel
Ballistic, gate-defined devices in two-dimensional materials offer a platform for electron optics phenomena influenced by the material's properties and gate control. We study the r…
Coupled deformed microdisk cavities featuring non-Hermitian properties
Tom Simon Rodemund, Síle Nic Chormaic, Martina Hentschel
Coupled cavities are of interest as they expose qualitatively new effects, such as non-Hermitian properties, that are beyond the possibilitie of individual cavities. Here, we inves…
