Order parameter steering by light
An emerging subject in nonequilibrium physics is “order parameter steering” where experimentally controllable perturbations (e.g., light pulses) may drive the order parameters of symmetry broken pha...

Three Facets of Understanding Pre-training: Loss, Inductive Bias, and Implicit Bias
AI is undergoing a paradigm shift with the rise of models pre-trained with self-supervisions and then adapted to a wide range of downstream tasks. However, their working largely remains a mystery; cla...

Probing the subatomic world using photon and electron scatterings
Photon and lepton scatterings from the nucleon and nuclei provide snapshots to their structure. A major goal of nuclear physics is to quantitively and comprehensively understand the internal dynamics ...

Coherent coupling of trapped ion mechanical oscillators for quantum information processing
I will present our recent progress in the coherent coupling of spectrally separated harmonic modes of motion of a trapped ion crystal and its applications. We realize high-fidelity coherent exchange o...
