Tracking the Ultrafast Non-Equilibrium Energy Flow between Electronic and Lattice Degrees of Freedom in Crystalline Nickel
P. Maldonado, T. Chase, A. H. Reid +9
Femtosecond laser excitation of solid-state systems creates non-equilibrium hot electrons that cool down by transferring their energy to other degrees of freedom and ultimately to…
Parallel-Plate Waveguides for Terahertz-Driven MeV Electron Bunch Compression
Mohamed A. K. Othman, Matthias C. Hoffmann, Michael K. Kozina +3
We demonstrate the electromagnetic performance of waveguides for femtosecond electron beam bunch manipulation and compression with strong-field terahertz (THz) pulses. The compress…
Light-Induced Charge Density Wave in LaTe
Anshul Kogar, Alfred Zong, Pavel E. Dolgirev +18
When electrons in a solid are excited with light, they can alter the free energy landscape and access phases of matter that are beyond reach in thermal equilibrium. This accessibil…
Diffractive imaging of dissociation and ground state dynamics in a complex molecule
Kyle Wilkin, Robert Parrish, Jie Yang +9
We have investigated the structural dynamics in photoexcited 1,2-diiodotetrafluoroethane molecules (C2F4I2) in the gas phase experimentally using ultrafast electron diffraction and…
Ultrafast decoupling of atomic sublattices in a charge-density-wave material
Jun Li, Junjie Li, Kai Sun +12
Atomic rearrangements within crystals lie at the foundation of electron-phonon-coupled phenomena such as metal-insulator transition and superconductivity. Advanced laser-pump-probe…
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…
