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…
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…
Chiral cavities made from lattices of highly electromagnetically-chiral scatterers
Lukas Rebholz, Carsten Rockstuhl, Ivan Fernandez-Corbaton
The infamous weakness of molecular chiroptical responses challenges the all-optical realization of crucial applications such as enantio-selective sorting of chiral molecules, or bi…
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…
A scalar product for the radiation of resonant modes
Maria Paszkiewicz-Idzik, Lukas Rebholz, Carsten Rockstuhl +1
We introduce the conformally-invariant scalar product, originally devised for radiation fields, to the study of the modes of optical resonators. This scalar product allows one to n…
Analyzing the acceleration time and reflectance of light sails made from homogeneous and core-shell spheres
Mitchell R. Whittam, Lukas Rebholz, Benedikt Zerulla +1
Deciding on appropriate materials and designs for use in light sails, like the one proposed in the Breakthrough Starshot Initiative, is a topic that requires much care and forethou…
Separating the Material and Geometry Contribution to the Circular Dichroism of Chiral Objects Made from Chiral Media
Lukas Rebholz, Marjan Krstić, Benedikt Zerulla +4
The chirality of an object can be studied by measuring the circular dichroism, that is, the difference in absorption of light with different helicity. The chiral optical response o…
