The dynamics of the photoelectric effect in solid-state systems can be investigated via attosecond-time-resolved photoelectron spectroscopy. This article provides a comparison of delay information accessible by the two most important techniques, atto

Plasmon polaritons (plasmons, for simplicity) have become paramount for tailored nanoscale light-matter interaction, and extensive research has been conducted to monitor(1,2) and manipulate their spatial(3) and spatio-temporal dynamics(4). These dyna

Golden Vogel spirals, as deterministic aperiodic structures, support isotropic photonic band gaps and have inter-esting applications. Localized modes, such as band-edge states, are essential for tailored light-matter interaction. Here we report imagi

We design and experimentally demonstrate an optical switch based on the interference of plasmonic modes in whispering gallery mode (WGM) antennas. Simultaneous excitation of even and odd WGM modes, enabled by a small symmetry breaking via non-normal

The brilliant white appearance of ultrathin scattering media with low refractive index contrast and the underlying radiative transport phenomena fascinate scientists for more than a decade. Examples of such systems are the scales of beetles of the ge

The complexity trap snaps and gives rise to misconceptions and even denialism when scientists leave their narrow field of expertise and uncritically use their well-trained epistemological concepts in areas where they do not apply. This mechanism is r

Recently, we presented a simple 3D model based on a combination of disordered Bragg stacks capable to entirely mimic the optical properties of the scales of the white beetle Cyphochilus. Due to its simplicity, we use this model here to investigate nu

Non-equilibrium photon correlations of coherently excited single quantum systems can reveal their internal quantum dynamics and provide spectroscopic access. Here we propose and discuss the fundamentals of a coherent photon coincidence spectroscopy b
