Photoelectrons resolve the phase-dependent variance of bright squeezed vacuum
Haoran Ma, Yihe Wang, Chuan Cheng +5
The variance of bright squeezed vacuum (BSV) is not only strong but also phase dependent, yet recent strong-field experiments with BSV have recorded only its magnitude. A coherent…
Tracking molecular hydrogen formation from ionized water in real time
Chuan Cheng, Chi-Hong Yuen, Eleanor Weckwerth +8
Removing an electron from a water molecule can drive its two hydrogen atoms to pair up and depart as molecular hydrogen. However, even for this elementary reaction, the route from…
Electron spectra from strong-field enhanced ionization in heavy water
Eleanor Weckwerth, Chuan Cheng, Ian Gabalski +6
Strong-field enhanced ionization (EI) is a phenomenon in which stretching of interatomic bonds into a distorted molecular geometry leads to an increase in the tunneling ionization…
Imaging valence electron rearrangement in a chemical reaction using hard X-ray scattering
Ian Gabalski, Alice Green, Philipp Lenzen +24
We have observed the signatures of valence electron rearrangement in photoexcited ammonia using ultrafast hard X-ray scattering. Time-resolved X-ray scattering is a powerful tool f…
Optical Interference Effect in Strong-field Electronic Coherence Spectroscopy
Eleanor Weckwerth, Andrew J. Howard, Chuan Cheng +6
We have investigated strong-field-induced electronic coherences in argon and molecular nitrogen ions created by high-intensity, few-cycle infrared laser pulses. This is a step towa…
Orientation-Dependent Enhanced Ionization in Acetylene Revealed by Ultrafast Cross-Polarized Pulse Pairs
S. A. Mohideen, A. J. Howard, C. Cheng +4
We investigate the orientation dependence of Enhanced Ionization (EI) during strong-field-driven nuclear motion in acetylene (CH). Here, we both initiate and probe molecula…
Imaging of chemical kinetics at the water-water interface in a free-flowing liquid flat-jet
H. Christian Schewe, Bruno Credidio, Aaron M. Ghrist +7
We present chemical kinetics measurements of the luminol oxydation chemiluminescence reaction at the interface between two aqueous solutions, using liquid jet technology. Free-flow…
Low-energy constraints on photoelectron spectra measured from liquid water and aqueous solutions
Sebastian Malerz, Florian Trinter, Uwe Hergenhahn +14
We report on the effects of electron collision and indirect ionization processes, occurring at photoexcitation and electron kinetic energies well below 30 eV on the photoemission s…
