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 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…
