Dr. Tzu-Chieh Wei will present a seminar on recent work:
"Realizing large-size quantum spin chains on cloud quantum computers,"

Abstract: Ultracold molecules have rich internal structure and tunable dipolar interactions, making them an exciting platform for studying quantum many-body physics. However, controlling molecular interactions, especially chemical reaction losses, has remained an experimental challenge. We demonstrate two approaches for tuning molecular interactions: strong 2D confinement and electric-field-induced shielding resonances.
Crossover from few-to many-body physics: The Efimov effect and the Bose polaron
Abstract: X-rays provide a unique spectroscopic view of molecules and
materials, from an element-specific and orbital-selective frame of
reference. Femtosecond and attosecond X-ray and extreme ultraviolet pulses
(XUV) are used to probe curve crossings and conical intersections in
molecules, electron and hole carriers in solids, coherent phonon motions,
and core hole excitons, revealing breathtaking 'movies' of novel, ultrashort
dynamical processes.
