Direct visualization of ultrafast lattice ordering triggered by an electron-hole plasma in 2D perovskites
Hao Zhang, Wenbin Li, Joseph Essman +18
Direct visualization of ultrafast coupling between charge carriers and lattice degrees of freedom in photo-excited semiconductors has remained a long-standing challenge and is crit…
Generation of Intense Phase-Stable Femtosecond Hard X-ray Pulse Pairs
Yu Zhang, Thomas Kroll, Clemens Weninger +24
Coherent nonlinear spectroscopies and imaging in the X-ray domain provide direct insight into the coupled motions of electrons and nuclei with resolution on the electronic length a…
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…
Carrier-Specific Femtosecond XUV Transient Absorption of PbI2 Reveals Ultrafast Nonradiative Recombination
Ming-Fu Lin, Max Verkamp, Joshua Leveillee +11
Femtosecond carrier recombination in PbI2 is measured using tabletop high-harmonic extreme ultraviolet (XUV) transient absorption spectroscopy and ultrafast electron diffraction. X…
