Gating upconversion electroluminescence in a single molecule via adsorption-induced interaction of unpaired spin
Vibhuti N. Rai, Christof Holzer, Carsten Rockstuhl +2
Molecules with unpaired spins (radicals) offer promising alternatives to closed-shell molecules as they are less limited regarding the spin statistics in their electroluminescence.…
Unified Evolution of Electromagnetic Sources in Homogeneous Fields
Ivanina Ilieva, Carsten Rockstuhl, Ivan Fernandez-Corbaton
In this work, we study the behavior of elementary electromagnetic sources, i.e., point-like electric charges and intrinsic magnetic dipoles, in the presence of homogeneous electrom…
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…
Predicting the optical properties of organometallic nanoparticles with a scale-bridging method: The importance of the embedding
Mariia Poleva, Benedikt Zerulla, Christof Holzer +7
It remains a prime question of how to describe the optical properties of large molecular clusters accurately. Quantum chemical methods capture essential electronic details but are…
Studying thermal radiation with T-matrices
Juan Diego Mazo-Vásquez, Markus Nyman, Marjan KrstiÄ +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…
