Competing excitonic couplings as origin of mimicked phase transitions in zinc-phthalocyanine single crystals
Lisa Schraut-May, Sebastian Hammer, Luca Nils Philipp +9
The optical properties of molecular crystals are largely determined by the excitonic coupling of neighboring molecules. This coupling is extremely sensitive to the arrangement of a…
Nuclear dynamics of singlet exciton fission: a direct observation in pentacene single crystals
Hélène Seiler, Marcin Krynski, Daniela Zahn +7
Singlet exciton fission (SEF) is a key process in the development of efficient opto-electronic devices. An aspect that is rarely probed directly, and yet has a tremendous impact on…
Probing exciton interaction with a spatially defined charge accumulation layer in the organic semiconductor Diindenoperylene
N. H. Hansen, C. Wunderlich, A. K. Topczak +1
We present an investigation of the microscopic interplay between excitons and charge carriers by means of combined photoluminescence (PL) and charge carrier transport measurements…
Ultrafast dynamics of charge density waves in 4Hb-TaSe2 probed by femtosecond electron diffraction
N. Erasmus, M. Eichberger, K. Haupt +6
The dynamics of the photoinduced commensurate to incommensurate charge density wave (CDW) phase transition in 4Hb-TaSe2 are investigated by femtosecond electron diffraction. In the…
Measurement of Magnetic-Field Structures in a Laser-Wakefield Accelerator
M. C. Kaluza, H. -P. Schlenvoigt, S. P. D. Mangles +6
Experimental measurements of magnetic fields generated in the cavity of a self-injecting laser-wakefield accelerator are presented. Faraday rotation is used to determine the existe…
On the Observation of Vacuum Birefringence
T. Heinzl, B. Liesfeld, K. -U. Amthor +3
We suggest an experiment to observe vacuum birefringence induced by intense laser fields. A high-intensity laser pulse is focused to ultra-relativistic intensity and polarizes the…
