Kuschel S, Ho P, Haddad A, Zimmermann F, Flueckiger L, Ware M, et al.
Nat Commun . 2025 Jan; 16(1):847. PMID: 39833149
Diffraction-before-destruction imaging with ultrashort X-ray pulses can visualize non-equilibrium processes, such as chemical reactions, with sub-femtosecond precision in the native environment. Here, a nanospecimen diffracts a single X-ray flash before...

Alexander O, Egun F, Rego L, Gutierrez A, Garratt D, Cardenas G, et al.
Sci Adv . 2024 Sep; 10(39):eadp0841. PMID: 39321305
We report the measurement of impulsive stimulated x-ray Raman scattering in neutral liquid water. An attosecond pulse drives the excitations of an electronic wavepacket in water molecules. The process comprises...

Driver T, Mountney M, Wang J, Ortmann L, Al-Haddad A, Berrah N, et al.
Nature . 2024 Aug; 632(8026):762-767. PMID: 39169246
The photoelectric effect is not truly instantaneous but exhibits attosecond delays that can reveal complex molecular dynamics. Sub-femtosecond-duration light pulses provide the requisite tools to resolve the dynamics of photoionization....

Alaa El-Din K, Alexander O, Frasinski L, Mintert F, Guo Z, Duris J, et al.
Sci Rep . 2024 Mar; 14(1):7267. PMID: 38538610
X-ray free-electron lasers are sources of coherent, high-intensity X-rays with numerous applications in ultra-fast measurements and dynamic structural imaging. Due to the stochastic nature of the self-amplified spontaneous emission process...

Li S, Lu L, Bhattacharyya S, Pearce C, Li K, Nienhuis E, et al.
Science . 2024 Feb; 383(6687):1118-1122. PMID: 38359104
Attosecond-pump/attosecond-probe experiments have long been sought as the most straightforward method for observing electron dynamics in real time. Although there has been much success with overlapped near-infrared femtosecond and extreme...

Li S, Driver T, Rosenberger P, Champenois E, Duris J, Al-Haddad A, et al.
Science . 2022 Jan; 375(6578):285-290. PMID: 34990213
In quantum systems, coherent superpositions of electronic states evolve on ultrafast time scales (few femtoseconds to attoseconds; 1 attosecond = 0.001 femtoseconds = 10 seconds), leading to a time-dependent charge...

ONeal J, Champenois E, Oberli S, Obaid R, Al-Haddad A, Barnard J, et al.
Phys Rev Lett . 2020 Aug; 125(7):073203. PMID: 32857563
Free-electron lasers provide a source of x-ray pulses short enough and intense enough to drive nonlinearities in molecular systems. Impulsive interactions driven by these x-ray pulses provide a way to...

MacArthur J, Duris J, Zhang Z, Lutman A, Zholents A, Xu X, et al.
Phys Rev Lett . 2019 Dec; 123(21):214801. PMID: 31809147
Electron beams with a sinusoidal energy modulation have the potential to emit subfemtosecond x-ray pulses in a free-electron laser. An energy modulation can be generated by overlapping a powerful infrared...

Driver T, Li S, Champenois E, Duris J, Ratner D, Lane T, et al.
Phys Chem Chem Phys . 2019 Dec; 22(5):2704-2712. PMID: 31793561
The recent demonstration of isolated attosecond pulses from an X-ray free-electron laser (XFEL) opens the possibility for probing ultrafast electron dynamics at X-ray wavelengths. An established experimental method for probing...

Coffee R, Cryan J, Duris J, Helml W, Li S, Marinelli A
Philos Trans A Math Phys Eng Sci . 2019 Apr; 377(2145):20180386. PMID: 30929632
The ability to produce ultrashort, high-brightness X-ray pulses is revolutionizing the field of ultrafast X-ray spectroscopy. Free-electron laser (FEL) facilities are driving this revolution, but unique aspects of the FEL...
