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…

Towards a fully differentiable digital twin for solar cells

Marie Louise Schubert, Houssam Metni, Jan David Fischbach +18

Maximizing energy yield (EY) - the total electric energy generated by a solar cell within a year at a specific location - is crucial in photovoltaics (PV), especially for emerging…

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…

A framework to compute resonances arising from multiple scattering

Jan David Fischbach, Fridtjof Betz, Nigar Asadova +8

Numerous natural and technological phenomena are governed by resonances. In nanophotonics, resonances often result from the interaction of several optical elements. Controlling the…

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…
