High resolution study of the yellow excitons in CuO subject to an electric field
J. Heckötter, M. Freitag, D. Fröhlich +4
We have used high resolution transmission spectroscopy to study the exciton level spectrum in CuO subject to a longitudinal external electric field, i.e., in the geometry where…
Field induced spontaneous quasiparticle decay and renormalization of quasiparticle dispersion in a quantum antiferromagnet
Tao Hong, Y. Qiu, M. Matsumoto +7
The notion of a quasiparticle, such as a phonon, a roton, or a magnon, is used in modern condensed matter physics to describe an elementary collective excitation. The intrinsic zer…
Enhancement of electron hot spot relaxation in photoexcited plasmonic structures by thermal diffusion
F. Spitzer, B. A. Glavin, V. I. Belotelov +6
We demonstrate that in confined plasmonic metal structures subject to ultra-fast laser excitation electron thermal diffusion can provide relaxation faster than the energy transfer…
