Momentum-Resolved View of Electron-Phonon Coupling in Multilayer WSe2
Lutz Waldecker,Lutz Waldecker,Roman Bertoni,Roman Bertoni,Hannes Hübener,Thomas Brumme,Thomas Vasileiadis,Daniela Zahn,Angel Rubio,Ralph Ernstorfer +9 more
TL;DR: A momentum-resolved picture of the energy transfer from excited electrons to phonons is obtained and this constitutes a basis for monitoring and predicting out of equilibrium electrical and thermal transport properties for nanoscale applications of TMDCs.

Nuclear dynamics of singlet exciton fission in pentacene single crystals.
Hélène Seiler,Marcin Krynski,Daniela Zahn,Sebastian Hammer,Yoav William Windsor,Thomas Vasileiadis,Jens Pflaum,Ralph Ernstorfer,Mariana Rossi,Mariana Rossi,Heinrich Schwoerer +10 more
TL;DR: In this paper, a femtosecond electron diffraction was used to directly observe the nuclear dynamics accompanying the Singlet exciton fission (SEF) process in single crystal pentacene using femto-condron diffraction.
Nuclear dynamics of singlet exciton fission: a direct observation in pentacene single crystals
Hélène Seiler,Marcin Krynski,Daniela Zahn,Sebastian Hammer,Yoav William Windsor,Thomas Vasileiadis,Jens Pflaum,Ralph Ernstorfer,Mariana Rossi,Heinrich Schwoerer +9 more
TL;DR: It is revealed that long-range motions play a decisive part in the electronic decoupling of the electronically correlated triplet pairs and shed light on why SEF occurs on ultrafast time scales.

Direct Observation of Ultrafast Lattice Distortions during Exciton–Polaron Formation in Lead Halide Perovskite Nanocrystals
Hélène Seiler,Daniela Zahn,Victoria C. A. Taylor,Maryna I. Bodnarchuk,Yoav William Windsor,Maksym V. Kovalenko,Ralph Ernstorfer +6 more
TL;DR: In this article , femtosecond electron diffraction was used to measure the sub-picosecond lattice dynamics of weakly confined CsPbBr3 nanocrystals following above-gap photoexcitation.

Lattice dynamics and ultrafast energy flow between electrons, spins, and phonons in a 3d ferromagnet.
Daniela Zahn,Florian Jakobs,Yoav William Windsor,Hélène Seiler,Thomas Vasileiadis,Tim A. Butcher,Yingpeng Qi,Dieter Engel,Unai Atxitia,Jan Vorberger,Ralph Ernstorfer +10 more
TL;DR: In this article, a femtosecond electron diffraction study of the ultrafast lattice response of nickel to laser excitation with ab initio calculations of the electron-phonon interaction and energy-conserving atomistic spin dynamics simulations is presented.
