The high-energy anomaly in ARPES spectra of the cuprates-many body or matrix element effect?
E. D. L. Rienks, M. Ärrälä, M. Lindroos +5
We used polarization-dependent angle-resolved photoemission spectroscopy (ARPES) to study the high-energy anomaly (HEA) in the dispersion of Nd2-xCexCuO4, (x=0.123). We have found…
Photoemission spectroscopy with high-intensity short-wavelength lasers
Song Bin Zhang, Nina Rohringer
We theoretically study the process of photoelectron emission of the Helium atom by a high-intensity short-wavelength laser at a resonance condition of the residual singly charged i…
Spatially separated polar samples of the cis and trans conformers of 3-fluorophenol
Thomas Kierspel, Daniel A. Horke, Yuan-Pin Chang +1
We demonstrate the spatial separation of the cis- and trans-conformers of 3-fluorophenol in the gas phase based on their distinct electric dipole moments. For both conformers we cr…
Spin-Orbit Effects in Atomic High-Harmonic Generation
Stefan Pabst, Robin Santra
Spin-orbit interactions lead to small energy gaps between the outer-most and shells of noble gas atoms. Strong-field pulses tunnel-ionize an electron out of eit…
Multi-mJ, kHz, 2.1-m OPCPA for high-flux soft X-ray high-harmonic radiation
Kyung-Han Hong, Chien-Jen Lai, Jonathas Siqueira +5
We report on a multi-mJ 2.1-m OPCPA system operating at a 1-kHz repetition rate, pumped by a picosecond cryogenic Yb:YAG pump laser, and the phase-matched high-flux high-harmoni…
A Threshold for Laser-Driven Linear Particle Acceleration in Unbounded Vacuum
Liang Jie Wong, Franz X. Kärtner
We hypothesize that a charged particle in unbounded vacuum can be substantially accelerated by a force linear in the electric field of a propagating electromagnetic wave only if th…
