Dynamics of a Persistent Insulator-to-Metal Transition in Strained Manganite Films
Samuel W. Teitelbaum, Benjamin K. Ofori-Okai, Yu-Hsiang Cheng +5
Transition metal oxides possess complex free energy surfaces with competing degrees of freedom. Photoexcitation allows shaping of such rich energy landscapes. In epitaxially strain…
Femtosecond compression dynamics and timing jitter suppression in a terahertz-driven electron bunch compressor
E. C. Snively, M. A. K. Othman, M. Kozina +8
We present the first demonstration of THz-driven bunch compression and timing stabilization of a few-fC relativistic electron beam with kinetic energy of 2.5 MeV using quasi-single…
Dynamical slowing down in an ultrafast photo-induced phase transition
Alfred Zong, Pavel E. Dolgirev, Anshul Kogar +20
Complex systems, which consist of a large number of interacting constituents, often exhibit universal behavior near a phase transition. A slowdown of certain dynamical observables…
Terahertz generation by beamlet superposition
Koustuban Ravi, Benjamin Ofori-Okai, Keith A. Nelson +1
We analytically show how a superposition of beamlets produces terahertz radiation with greater spatial homogeneity and efficiency compared to tilted-pulse-fronts generated by diffr…
Setup for meV-resolution inelastic X-ray scattering measurements at the Matter in Extreme Conditions Endstation at the LCLS
E. E. McBride, T. G. White, A. Descamps +24
We describe a setup for performing inelastic X-ray scattering measurements at the Matter in Extreme Conditions (MEC) endstation of the Linac Coherent Light Source (LCLS). This tech…
Terahertz-based attosecond metrology of relativistic electron beams
R. K. Li, M. C. Hoffmann, E. A. Nanni +9
Photons, electrons, and their interplay are at the heart of photonic devices and modern instruments for ultrafast science [1-10]. Nowadays, electron beams of the highest intensity…
