With the increasing demand for miniaturized devices and integrated circuits, ultrasmall-scale
device units have attracted increasing attention. However, the short-channel effects severely …

Resolving the complete electron scattering dynamics mediated by coherent phonons is
crucial for understanding electron-phonon couplings beyond equilibrium. Here we present a …

Layered transition-metal dichalcogenides (TMDs) are model systems to explore ultrafast
many-body interactions and various nonlinear optical phenomena. For the application of …

Driving fundamental excitations via strong light fields is one of the most important issues in
solid state physics, which opens up new avenues to control material properties. Two …

We theoretically investigate the behavior of coherent optical phonons in an electron–phonon
coupled system at moderate laser intensity: below GW/cm 2. We calculate the coherent …

We investigated femtosecond laser ablation dynamics using THz time-domain spectroscopy.
To clarify the breakdown dynamics of materials, we focused on the motion of charged …

“Plus ultra.”–the national motto of Spain and/or the school motto of Yu-ei high school in a
comic “My Hero Academia” written and illustrated by Kohei Horikoshi. Humans have grown …
