Optical absorption activated by an ultrashort half-cycle pulse in metallic and superconducting states of the Hubbard model
Kazuya Shinjo, Shigetoshi Sota, Seiji Yunoki +1
The development of high-intensity ultrashort laser pulses unlocks the potential of pump-probe spectroscopy in sub-femtosecond timescale. Notably, subcycle pump pulses can generate…
