Extracting Nonlinear Dynamical Response Functions from Time Evolution
Atsushi Ono
We develop a general framework based on the functional derivative to extract nonlinear dynamical response functions from the temporal evolution of physical quantities, without expl…

Temporal modulation of second harmonic generation in ferroelectrics by a pulsed electric field
Atsushi Ono
We revisit the relationship between electric polarization modulation in ferroelectrics induced by a low-frequency pulsed electric field and the corresponding second harmonic i…
