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…
Fast array-based particle coincidence detection in a TimePix3-based velocity map imaging instrument
Ian Gabalski, Eleanor Weckwerth, Chuan Cheng +1
With the development of high repetition rate laser sources and advanced multi-particle correlation analyses such as covariance mapping, particle detection techniques such as veloci…
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…
Femtosecond electronic and hydrogen structural dynamics in ammonia imaged with ultrafast electron diffraction
Elio G. Champenois, Nanna H. List, Matthew Ware +18
Directly imaging structural dynamics involving hydrogen atoms by ultrafast diffraction methods is complicated by their low scattering cross-sections. Here we demonstrate that megae…
Filming Enhanced Ionization in an Ultrafast Triatomic Slingshot
A. J. Howard, M. Britton, Z. L. Streeter +10
Filming atomic motion within molecules is an active pursuit of molecular physics and quantum chemistry. A promising method is laser-induced Coulomb Explosion Imaging (CEI) where a…
