Table-top interferometry on extreme time and wavelength scales
S. Skruszewicz, A. Przystawik, D. Schwickert +12
High-resolution Fourier-transform spectroscopy using table-top sources in the extreme ultraviolet (XUV) spectral range is still in its infancy. In this contribution a significant a…
Electronic Quantum Coherence in Glycine Molecules Probed with Ultrashort X-ray Pulses in Real Time
David Schwickert, Marco Ruberti, Přemys Kolorenč +25
Quantum coherence between electronic states of a photoionized molecule and the resulting process of ultrafast electron-hole migration have been put forward as a possible quantum me…
Attosecond interferometry with self-amplified spontaneous emission of a free-electron laser
Sergey Usenko, Andreas Przystawik, Markus Jakob +6
Light-phase-sensitive techniques, such as coherent multidimensional spectroscopy, are well-established in a broad spectral range, already spanning from radio-frequencies in nuclear…
Bright Discrete Solitons in Spatially Modulated DNLS Systems
P. G. Kevrekidis, R. L. Horne, N. Whitaker +2
In the present work, we revisit the highly active research area of inhomogeneously nonlinear defocusing media and consider the existence, spectral stability and nonlinear dynamics…
Asymmetric Wave Propagation Through Saturable Nonlinear Oligomers
Daniel Law, Jennie D'Ambroise, Panayotis G. Kevrekidis +1
In the present paper we consider nonlinear dimers and trimers (more generally, oligomers) embedded within a linear Schr{ö}dinger lattice where the nonlinear sites are of saturable…
Revisiting the PT-symmetric Trimer: Bifurcations, Ghost States and Associated Dynamics
K. Li, P. G. Kevrekidis, D. J. Frantzeskakis +2
In this paper, we revisit one of the prototypical PT-symmetric oligomers, namely the trimer. We find all the relevant branches of "regular" solutions and analyze the bifurcations a…
