Simultaneous Observation of Carrier-Specific Redistribution and Coherent Lattice Dynamics in 2H-MoTe with Femtosecond Core-Level Spectroscopy
Andrew R. Attar, Hung-Tzu Chang, Alexander Britz +12
We employ few-femtosecond extreme ultraviolet (XUV) transient absorption spectroscopy to reveal simultaneously the intra- and interband carrier relaxation and the light-induced str…

Design and Characteristics of a Population Inversion X-ray Laser Oscillator
A. Halavanau, A. Benediktovitch, A. A. Lutman +5
Oscillators are at the heart of optical lasers, providing stable transform limited pulses. In contrast, X-ray free electron lasers use self-amplified spontaneous emission (SASE), r…

Double Core Hole Valence-to-Core X-ray Emission Spectroscopy: A Theoretical Exploration Using Time-Dependent Density Functional Theory
Yu Zhang, Uwe Bergmann, Robert W. Schoenlein +2
With the help of newly developed X-ray free-electron laser (XFEL) sources, creating double core holes simultaneously at the same or different atomic sites in a molecule has now bec…
