High harmonic generation in crystalline solids has been examined so far on the basis of one-
body energy-band structures arising from electron itineracy in a periodic potential. Here, we …

Nonlinear responses in condensed matter are intensively studied because they provide rich
information about the materials and hold the possibility of being applied in diodes or high …

Understanding dephasing mechanisms of strong-field-driven excitons in condensed matter
is essential for their applications in quantum-state manipulation and ultrafast optical …

Theoretical calculations of high-harmonic generation (HHG) from commensurate twisted
bilayer graphene (tBLG) under intense laser fields are performed. The nonlinear electron …

Floquet engineering, the nonthermal manipulation of material properties on ultrafast
timescales using strong and time-periodic laser fields, has led to many intriguing …

We analyze high-order harmonic generation (HHG) in a disordered semiconductor within
the context of the Anderson model of disorder. Employing the theoretical methods pioneered …

Controlling the electron dynamics during laser-matter interactions is a key factor to control
the energy deposition and subsequent material modifications induced by femtosecond laser …

We study weak traces of particle passing Vaidman's nested Mach–Zehnder interferometer.
We investigate an effect of decoherence caused by an environment coupled to internal …

The evolution of quantum optical systems is determined by three key factors: the interactions
with their surrounding environment, externally controlled lasers and between the different …

The at-will control of quantum states is a primary goal of quantum science and technology.
The celebrated Hahn echo exemplifies such quantum-state control based on a time-reversal …
