WebMay 17, 2024 · This limited freedom of motion hinders the infamous “Rydberg-avalanching-loss” process by which Rydberg atoms collide, gain kinetic energy, and escape the trap. The long-range interaction and the consequent hopping motion of the fermions generate many-body excitations—commonly called quantum fluctuations—on top of the Fermi sea. WebThe SACLA (SPring-8 Angstrom compact laser) was designed to significantly downsize the SASE (self-amplified spontaneous emission) type XFEL (X-ray free-electron laser), in order to generate coherent light in the wavelength region of 0.1 nm by adopting an in-vacuum undulator that can shorten the magnetic field period length.
