Spatio-temporal breather dynamics in microcomb soliton crystals
We explore and observe the spatio-temporal breather dynamics of optical soliton frequency comb crystals, examining spatial breathers, chaos transitions, and dynamical switching – in nonlinear measurements and theory.

Coulomb focusing in attosecond angular streaking
This study demonstrates the Coulomb focusing in nonadiabatic tunneling ionization inducing the convergence of electrons emitted at different initial ionization times to the same emission angle, thereby breaking the one‐to-one correspondence—one of the fundamental assumption in attosecond angular streaking.

Broadband infrared imaging governed by guided-mode resonance in dielectric metasurfaces
We experimentally demonstrate high-quality infrared imaging ranging from >1000 to 4000 nanometers with Si metasurfaces based on four-wave mixing (FWM) processes, by employing a pump beam at resonant position.
