Journal ArticleDOI
Resonant internal Quantum transitions and femtosecond radiative decay of excitons in monolayer WSe2
C. Poellmann,Philipp Steinleitner,U. Leierseder,Philipp Nagler,Gerd Plechinger,Michael Porer,Rudolf Bratschitsch,Christian Schüller,Tobias Korn,Rupert Huber +9 more
TL;DR: In this article, the 1s-2p resonance of 1s A excitons in a single-layer WSe2 was analyzed and the decay dynamics of small-momentum exciton decay was shown to be ultrafast.
Journal ArticleDOI
Non-thermal separation of electronic and structural orders in a persisting charge density wave
Michael Porer,U. Leierseder,Jean-Michel Ménard,Hatem Dachraoui,Leonidas Mouchliadis,Ilias E. Perakis,Ulrich Heinzmann,Jure Demsar,Kai Rossnagel,Rupert Huber +9 more
TL;DR: In this paper, the electronic and structural components of charge density waves occurring in layered transition metal dichalcogenides are known to be interdependent, yet have only been probed in separate measurements.
Journal ArticleDOI
Ultrafast transient generation of spin-density-wave order in the normal state of BaFe2As2 driven by coherent lattice vibrations
Kyung Wan Kim,Kyung Wan Kim,Kyung Wan Kim,Alexej Pashkin,Hanjo Schäfer,M. Beyer,Michael Porer,Michael Porer,T. Wolf,Christian Bernhard,Jure Demsar,Jure Demsar,Rupert Huber,Rupert Huber,Alfred Leitenstorfer +14 more
TL;DR: A pronounced spin-phonon coupling in pnictides that supports rapid development of a macroscopic order on small vibrational displacement even without breaking the symmetry of the crystal is attest to.
Journal ArticleDOI
Femtosecond response of quasiparticles and phonons in superconducting YBa(2)Cu(3)O(7-δ) studied by wideband terahertz spectroscopy.
Alexej Pashkin,Michael Porer,M. Beyer,Kyung Wan Kim,Kyung Wan Kim,Adam Dubroka,Christian Bernhard,Xin Yao,Yoram Dagan,Rudi Hackl,Andreas Erb,Jure Demsar,Jure Demsar,Rupert Huber,Alfred Leitenstorfer +14 more
TL;DR: This work measures the anisotropic midinfrared response of electrons and phonons in bulk YBa(2)Cu(3)O(7-δ) after femtosecond photoexcitation and introduces a powerful concept probing electron-lattice interactions in a variety of complex materials.
Journal ArticleDOI
The Ultrafast Einstein-De Haas Effect

Alberca,Yoav William Windsor,Yoav William Windsor,Paul Beaud,Urs Staub,Diling Zhu,Sanghoon Song,James M. Glownia,Steven L. Johnson,Steven L. Johnson +26 more
TL;DR: In this article, it was shown that a large fraction of the angular momentum associated with the aligned electron spins in a ferromagnet can be converted to mechanical angular momentum by reversing the direction of magnetisation using an external magnetic field.
