We study strong-field molecular ionization as a function of pulse duration. Experimental measurements of the photoelectron yield for a number of molecules reveal competition between different ionization continua (cationic states) which depends strongly on pulse duration. Surprisingly, in the limit of short pulse duration, we find that a single ionic continuum dominates the yield, whereas multiple continua are produced for longer pulses. Using calculations which take vibrational dynamics into…

Experimental Separation of Subcycle Ionization Bursts in Strong-Field Double Ionization of H_{2}.
We report on the unambiguous observation of the subcycle ionization bursts in sequential strong-field double ionization of H_{2} and their disentanglement in molecular frame photoelectron angular
Competition between dynamic resonance and internal conversion in strong-field molecular ionization with chirped ultrafast laser pulses
The authors show theoretically and experimentally how the time-varying phase or frequency of a chirped strong-field ultrafast laser pulse can be used to control the ionization yield to different
Electron correlation in channel-resolved strong-field molecular double ionization
Strong-field ionization plays a fundamental role in attosecond science as the source of electron wave packets which ultimately provide attosecond bursts of radiation as they are driven back to the
Sequential and direct ionic excitation in the strong-field ionization of 1-butene molecules.
A striking transition is observed in the fragment-associated photoelectron spectra: from a single Above Threshold Ionization (ATI) progression for photon energies less than the cation D0-D1 gap to two ATI progressions for a photon energy greater than this gap.
Coherent Control of Internal Conversion in Strong-Field Molecular Ionization.
We demonstrate coherent control over internal conversion during strong-field molecular ionization with shaped, few-cycle laser pulses. The control is driven by interference in different neutral
Non-adiabatic few-femtosecond dynamics of excited methanol with super-resolution time-resolved photoelectron spectroscopy
We report a novel approach to tracking nuclear motion and non-adiabatic dynamics in molecular systems, on sub-10\,fs timescales, by combining a detailed analysis of the onset and decay times of the
The importance of Rydberg orbitals in dissociative ionization of small hydrocarbon molecules in intense laser fields
The measured angular distributions and intensity dependence show that field-dressed orbitals can have strong Rydberg character for certain orientations of the molecule relative to the laser polarization and that they may contribute significantly to the hydrogen elimination dissociative ionization yield.

Abstract The description with traditional methods of the single or multiple ionization of atoms and molecules by two or more successive photons requires some special treatment. Difficulties occur

A new language, Opt, is proposed for writing these objective functions over image- or graph-structured unknowns concisely and at a high level and automatically transforms these specifications into state-of-the-art GPU solvers based on Gauss-Newton or Levenberg-Marquardt methods.
It is demonstrated that Ga-PSMA PET/CT has a high overall diagnostic value for LN staging in patients with moderate and high-risk PCa, but the conclusions still require a larger sample size, multi-center prospective randomized controlled trial to verify.
