The Bloch-Nordsieck propagator at finite temperature
Jean-Paul Blaizot, Edmond Iancu, Service de Physique Theorique +2
We have shown recently that the resummation of soft photon contributions leads to a non-exponential decay of the fermion excitations in hot QED plasmas. The retarded propagator of…
Harmony search to solve the container storage problem with different container types
I. Ayachi, R. Kammarti, M. Ksouri +6
This paper presents an adaptation of the harmony search algorithm to solve the storage allocation problem for inbound and outbound containers. This problem is studied considering m…
Effects of realistic pulse shapes in two-dimensional spectroscopy
M. Russo, R. Gilliot, A. Blech +12
Two-dimensional (2D) spectroscopy is a powerful pump-pump-probe technique for revealing couplings between quantum states and disentangling the different contributions to the optica…
High-energy and Very High-energy Constraints from Log-parabolic Spectral Models in Narrow-line Seyfert 1 Galaxies
Stefano Vercellone, Luigi Foschini, Patrizia Romano +20
Narrow-line Seyfert 1 galaxies (NLSy1s) are a well-established class of -ray sources, showing the presence of a jet like the more common flat-spectrum radio quasars. The eviden…
NuSTAR Discovery of a cyclotron line in KS 1947+300
Felix Fuerst, Katja Pottschmidt, Joern Wilms +39
We present a spectral analysis of three simultaneous NuSTAR and Swift/XRT observations of the transient Be-neutron star binary KS 1947+300 taken during its outburst in 2013/2014. T…
Lifetime of quasiparticles in hot gauge theories
Edmond Iancu, Service de Physique Theorique, Saclay +1
The perturbative calculation of the lifetime of charged excitations in ultrarelativistic plasmas is plagued with infrared divergences which are not eliminated by the screening corr…
