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…
Unveiling clean two-dimensional discrete time crystals on a digital quantum computer
Kazuya Shinjo, Kazuhiro Seki, Tomonori Shirakawa +2
In periodically driven (Floquet) systems, evolution typically results in an infinite-temperature thermal state due to continuous energy absorption over time. However, before reachi…
Keldysh crossover in one-dimensional Mott insulators
Kazuya Shinjo, Takami Tohyama
Recent advancements in pulse laser technology have facilitated the exploration of non-equilibrium spectroscopy of electronic states in the presence of strong electric fields across…
