On Sub-Sevenfold Symmetries in LH2 Stacked Ring Scaffolds: A Quantum Optical Perspective
Arpita Pal
Using a closed quantum optical coupled-dipole model, we investigate why sub-sevenfold symmetries are likely absent in the stacked-ring scaffolds of light-harvesting 2 (LH2) complex…

Selective Preparation of Collective States in Coupled Quantum Emitters Using the SUPER Excitation Scheme
Johannes Kerber, Laurin Ostermann, Vikas Remesh +2
The efficient preparation of collective eigenstates of subwavelength-spaced optical dipoles is a prerequisite for observing their signature radiative properties and for their appli…

Efficient excitation transfer in an LH2-inspired nanoscale stacked ring geometry
Arpita Pal, Raphael Holzinger, Maria Moreno-Cardoner +1
Subwavelength ring-shaped structures of quantum emitters exhibit outstanding radiation properties and are useful for antennas, excitation transport, and storage. Taking inspiration…
