Attosecond Transient Polarimetry
Nicola Mayer, Kylie Gannan, Stephen R Leone +1
We introduce elliptical-dichroic attosecond transient absorption spectroscopy (eDATAS), an ultrafast attosecond spectroscopy technique in which an atomic gas is probed by elliptica…
Probing of Core Excitons in Solid NaF with Polarization-Selective Attosecond Time-Resolved Four-Wave Mixing Spectroscopy
Kevin Gulu Xiong, Rafael Quintero-Bermudez, Vincent Eggers +3
Nonlinear Four-wave mixing processes are a powerful technique to unravel ultrafast dynamics in solid-state systems. Here, we employ attosecond four-wave mixing spectroscopy with on…
From interface-limited to Auger-dominated carrier dynamics in -SnS
Hugo Laurell, Kevin Xiong, Nedjma Ouahioune +10
Metastable cubic tin(II) sulfide (-SnS) is an earth-abundant semiconductor whose three-dimensionally bonded chiral lattice may overcome the short minority-carrier lifetime of or…
Background-free Tracking of Ultrafast Hole and Electron Dynamics with XUV Transient Grating Spectroscopy
Vincent Eggers, Rafael Quintero-Bermudez, Kevin Gulu Xiong +1
Extreme ultraviolet (XUV) transient absorption (TA) and transient reflectivity (TR) spectroscopies enable element-specific insights into attosecond-timescale processes in solids. X…
Different Rise Times of Atomic Br M 3d Core Level Absorptions during Br C State Dissociation via Extreme Ultraviolet Transient Absorption Spectroscopy
John E. Beetar, Jen-Hao Ou, Yuki Kobayashi +1
The reported ''dissociation times'' for the Br C ( ) state by various measurement methods differ widely across the literature (30 to 340 fs). We consider th…
