All-optical logic gates for extreme ultraviolet switching via attosecond four-wave mixing
Patrick Rupprecht, Daniel M. Neumark, Stephen R. Leone
All-optical logic-gate-based switching is a prerequisite for photonic computing. This article introduces a logic-gate protocol for noncollinear four-wave mixing (FWM) of one attose…
Tracing long-lived atomic coherences generated via molecular conical intersections
Patrick Rupprecht, Francesco Montorsi, Lei Xu +7
Accessing coherences is key to fully understand and control ultrafast dynamics of complex quantum systems like molecules. Most photochemical processes are mediated by conical inter…
Extreme Ultraviolet Time-Resolved Photoelectron Spectrometer with an Ultrathin Liquid Flat Jet
Masafumi Koga, Do Hyung Kang, Zachary N. Heim +2
A setup for extreme-ultraviolet time-resolved photoelectron spectroscopy (XUV-TRPES) of liquids is described based on a gas-dynamic flat jet formed by a microfluidic chip device. I…
Extracting doubly-excited state lifetimes in helium directly in the time domain with attosecond noncollinear four-wave-mixing spectroscopy
Patrick Rupprecht, Nicolette G. Puskar, Daniel M. Neumark +1
The helium atom, with one nucleus and two electrons, is a prototypical system to study quantum many-body dynamics. Doubly-excited states, or quantum states in which both electrons…
Theoretical analysis of the role of complex transition dipole phase in XUV transient-absorption probing of charge migration
Yuki Kobayashi, Daniel M. Neumark, Stephen R. Leone
We theoretically investigate the role of complex dipole phase in the attosecond probing of charge migration. The iodobromoacetylene ion (ICCBr) is considered as an example, in…
