Autoionizing polaritons with the Jaynes-Cummings model
Coleman Cariker, Sergio Yanez-Pagans, Nathan Harkema +3
Intense laser pulses have the capability to couple resonances in the continuum, leading to the formation of a split pair of autoionizing polaritons. These polaritons can exhibit ex…
Multi-polariton control in attosecond transient absorption of autoionizing states
S. Yanez-Pagans, C. Cariker, M. Shaikh +2
Tunable attosecond transient absorption spectroscopy is an ideal tool for studying and manipulating autoionization dynamics in the continuum. We investigate near-resonant two-photo…
Raman interferometry between autoionizing states to probe ultrafast wavepacket dynamics with high spectral resolution
A. Plunkett, M. A. Alarcon, J. K. Wood +2
Photoelectron interferometry with femto- and atto-second light pulses is a powerful probe of the fast electron wavepacket dynamics, albeit it has practical limitations on the energ…
Nanopatterned electron beams for temporal coherence and deterministic phase control of x-ray free-electron lasers
W. S. Graves, S. L. Y. Chang, D. Dwyer +11
We demonstrate the ability to create electron beams with high-contrast, nanometer-scale density modulations as a first step toward developing full control of the phase fronts of an…
Ultrafast relaxation of hot phonons in Graphene-hBN Heterostructures
Dheeraj Golla, Alexandra Brasington, Brian J. LeRoy +1
Fast carrier cooling is important for high power graphene based devices. Strongly Coupled Optical Phonons (SCOPs) play a major role in the relaxation of photoexcited carriers in gr…
Probing autoionizing states of molecular oxygen with XUV transient absorption: Electronic symmetry dependent lineshapes and laser induced modification
Chen-Ting Liao, Xuan Li, Daniel J. Haxton +4
The dynamics of autoionizing Rydberg states of oxygen are studied using attosecond transient absorption technique, where extreme ultraviolet (XUV) initiates molecular polarization…
