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…
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…
Efficient computation of thermal radiation from biperiodic layered systems using the T-matrix method
Martin Gabbert, Markus Nyman, Lukas Rebholz +2
Metasurfaces are becoming important tools for the control of thermal radiation. Understanding their functional possibilities on computational grounds requires evaluating the respon…
Photonic time crystals assisted by quasi-bound states in the continuum
P. Garg, E. Almpanis, L. Zimmer +8
Photonic time crystals are a class of artificial materials that have only recently been explored. They are characterized by the ultrafast modulation of the material properties in t…
Studying thermal radiation with T-matrices
Juan Diego Mazo-Vásquez, Markus Nyman, Marjan Krstić +3
We introduce a basic formalism for computing thermal radiation by combining Waterman's T-matrix method with an algebraic approach to light-matter interactions. The formalism applie…
