Broken-symmetry phenomena enhanced by quasi-bound states in the continuum

Jan David Fischbach, Lukas Rebholz, Nikita Ustimenko +3

Many of the most powerful and elegant models in physics are grounded in symmetries. In electrodynamics, for example, geometric symmetries govern the observable effects of light-mat…

Pole-Expansion of the T-Matrix Based on a Matrix-Valued AAA-Algorithm

Jan David Fischbach, Fridtjof Betz, Lukas Rebholz +6

The transition matrix (T-matrix) is a complete description of an object's linear scattering response. As such, it has found wide adoption for the theoretical and computational desc…

Gradient-based optimization of scatterer arrangements based on the T-matrix method

Nigar Asadova, Jan David Fischbach, Renaud Vallée +6

The demand for inverse design is increasing as the ability to fabricate sub-10 nm features expands the design space by orders of magnitude. Efficient inverse design benefits from d…

Resonant states reveal strong light-matter coupling in nanophotonic cavities

Jan David Fischbach, Sergei Gladyshev, Adrià Canós Valero +3

Photonic resonances enable control over light-matter interactions, but many key phenomena only emerge in the strong-coupling regime where light and matter excitations fully hybridi…

Photonic time crystals assisted by quasi-bound states in the continuum

P. Garg, E. Almpanis, L. Zimmer +8

Photonic time crystals (PTCs) are characterized by the rapid modulation of the material properties in time, causing a momentum bandgap for light. However, the observation of these…

Wide angle tolerant solar spectral splitter for lateral tandem solar cells

M. L. Schubert, J. D. Fischbach, M. Nyman +4

Maximizing the power conversion efficiency of solar cells plays a crucial role in upscaling solar energy production. Combining two or more solar cells with different bandgaps into…

Inverse-designed dispersive time-varying nanostructures

Puneet Garg, Jan David Fischbach, Aristeidis G. Lamprianidis +5

Time-varying nanostructures allow us to control the spatial and temporal properties of light. The temporal modulation of the nanostructures constitutes an additional degree of free…
