Topological Frenkel excitons in 2D molecular crystals
Quentin Stein, Sidhartha Nayak, Song Jiang +7
Collective molecular excitations govern energy transport in light-harvesting and optoelectronic materials. Theory predicts that excitonic band topology can generate edge-confined s…
Momentum-Locked Edge Excitons in 2D Molecular Crystals
Sidhartha Nayak, Alex Boeglin, Quentin Stein +4
In molecular crystals, molecular excitations can hybridize into collective Frenkel excitons. Here we show that doubly degenerate excitations in planar two-dimensional molecular cry…
Hyperfine interactions in open-shell planar -carbon nanostructures
Sanghita Sengupta, Thomas Frederiksen, Geza Giedke
We investigate hyperfine interaction (HFI) using density-functional theory for several open-shell planar -carbon nanostructures displaying magnetism. Our prototype struct…
Bistability between -diradical open-shell and closed-shell states in indeno[1,2-a]fluorene
Shantanu Mishra, Manuel Vilas-Varela, Leonard-Alexander Lieske +7
Indenofluorenes are non-benzenoid conjugated hydrocarbons that have received great interest owing to their unusual electronic structure and potential applications in non-linear opt…
Mach--Zehnder-like interferometry with graphene nanoribbon networks
Sofia Sanz, Nick Papior, Géza Giedke +3
We study theoretically electron interference in a Mach--Zehnder-like geometry formed by four zigzag graphene nanoribbons (ZGNRs) arranged in parallel pairs, one on top of the other…
Detecting the spin-polarization of edge states in graphene nanoribbons
Jens Brede, Nestor Merino-Díez, Alejandro Berdonces +9
Low dimensional carbon-based materials are interesting because they can show intrinsic -magnetism associated to p-electrons residing in specific open-shell configurations. Conse…
