High-harmonic fingerprints of sharp spin twists in a chiral soliton lattice
Atsushi Ono
A magnetic field applied perpendicular to the helical axis of a monoaxial chiral helimagnet compresses the spin helix into a coplanar chiral soliton lattice (CSL). We show that opt…
Floquet Green's functions for lattice electrons driven by Gaussian quantum light
Atsushi Ono
We formulate Floquet Green's functions for noninteracting single-band lattice electrons driven by a reservoir-stabilized single-mode Gaussian quantum light source. The source is pr…
Tangent equations of motion for nonlinear response functions
Atsushi Ono
Nonlinear response functions, formulated as multipoint correlation functions or Volterra kernels, encode the dynamical and spectroscopic properties of physical systems and underpin…
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…
Electron dynamics induced by quantum cat-state light
Shohei Imai, Atsushi Ono, Naoto Tsuji
We present an effective theory for describing electron dynamics driven by an optical external field in a Schrödinger's cat state. We show that the reduced electron density matrix e…
High harmonic generation from electrons moving in topological spin textures
Atsushi Ono, Shun Okumura, Shohei Imai +1
High harmonic generation (HHG) is a striking phenomenon, which reflects the ultrafast dynamics of electrons. Recently, it has been demonstrated that HHG can be used to reconstruct…
