Coherent vibrational wave packet motion in ErCry4a proteins monitors the redox state of the flavin chromophore
Krishan Kumar, Daniel Timmer, Maryam Khazani +8
Cryptochromes are blue-light-sensitive flavoproteins that play central roles in biological function. In European robin (Erithacus rubecula) ErCry4a proteins, optical excitation of…
Nonadiabatic couplings drive ultrafast, mode-selective intramolecular vibrational energy redistribution in flavins
Daniel Timmer, Krishan Kumar, Jan P. Götze +3
Flavins are the chromophores in several blue-light-sensitive photoreceptor proteins and act as redox cofactors in many enzymes relevant for biological processes. Despite their biol…
Ultrafast dynamics of coherent exciton-polaritons in van der Waals semiconductor metasurfaces
Luca Sortino, Armando Genco, Cristina Cruciano +14
Enabling coherent light-matter interactions is a critical step toward next-generation quantum technologies. However, achieving this under ambient temperature conditions remains cha…
Ultrafast transition from coherent to incoherent polariton nonlinearities in a hybrid 1L-WS2/plasmon structure
Daniel Timmer, Moritz Gittinger, Thomas Quenzel +14
Exciton polaritons based on atomically thin semiconductors are essential building blocks of quantum optoelectronic devices. Their properties are governed by an ultrafast and oscill…
Roadmap for Photonics with 2D Materials
F. Javier GarcÃa de Abajo, D. N. Basov, Frank H. L. Koppens +145
Triggered by the development of exfoliation and the identification of a wide range of extraordinary physical properties in self-standing films consisting of one or few atomic layer…
Two-dimensional electronic spectroscopy of organic semiconductor nanostructures
Daniel Timmer, Christoph Lienau
This chapter discusses recent experimental work exploring the optical properties and quantum dynamics of organic semiconductor nanostructures based on squaraine dyes. Squaraines ar…
