Non-resonant Coherent Amplitude Transfer in Attosecond Four-Wave Mixing Spectroscopy
James D. Gaynor, Ashley P. Fidler, Yuki Kobayashi +4
Attosecond four-wave mixing spectroscopy using an XUV pulse and two noncollinear near-infrared pulses is employed to measure Rydberg wavepacket dynamics resulting from extreme ultr…
Floquet engineering of strongly-driven excitons in monolayer tungsten disulfide
Yuki Kobayashi, Christian Heide, Amalya C. Johnson +4
Interactions of quantum materials with strong-laser fields can induce exotic nonequilibrium electronic states. Monolayer transition-metal dichalcogenides, a new class of direct-gap…
Calibration and performance of the readout system based on switched capacitor arrays for the Large-Sized Telescope of the Cherenkov Telescope Array
Seiya Nozaki, Kyosuke Awai, Aya Bamba +59
The Cherenkov Telescope Array (CTA) is the next-generation ground-based very-high-energy gamma-ray observatory. The Large-Sized Telescope (LST) of CTA is designed to detect gamma r…
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…
Probing Electron-Hole Coherence in Strongly-Driven Solids
Christian Heide, Yuki Kobayashi, Amalya Johnson +4
High-harmonic generation (HHG) is a coherent optical process in which the incident photon energy is up-converted to the multiples of its initial energy. In solids, under the influe…
Attosecond XUV probing of vibronic quantum superpositions in Br
Yuki Kobayashi, Daniel M. Neumark, Stephen R. Leone
Ultrafast laser excitation can create coherent superpositions of electronic states in molecules and trigger ultrafast flow of electron density on few- to sub-femtosecond time scale…
Revealing electronic state-switching at conical intersections in alkyl iodides by ultrafast XUV transient absorption spectroscopy
Kristina F. Chang, Maurizio Reduzzi, Han Wang +6
Conical intersections between electronic states often dictate the chemistry of photoexcited molecules. Recently developed sources of ultrashort extreme ultraviolet (XUV) pulses tun…
Coherent electronic-vibrational dynamics in deuterium bromide probed via attosecond transient absorption spectroscopy
Yuki Kobayashi, Kristina F. Chang, Sonia Marggi Poullain +4
Ultrafast laser excitation can trigger multiplex coherent dynamics in molecules. Here, we report attosecond transient absorption experiments addressing simultaneous probing of elec…
Attosecond spectroscopy reveals alignment dependent core-hole dynamics in the ICl molecule
Hugo J. B. Marroux, Ashley P. Fidler, Aryya Ghosh +5
The removal of electrons located in the core shells of molecules creates transient states that live between a few femtoseconds to attoseconds. Owing to these short lifetimes, time-…
Gas-phase structural isomer identification by Coulomb explosion of aligned molecules
Michael Burt, Kasra Amini, Jason W. L. Lee +7
The gas-phase structures of four difluoroiodobenzene and two dihydroxybromobenzene isomers were identified by correlating the emission angles of atomic fragment ions created follow…
