Excitonic optical spectra and energy structures in a one-dimensional Mott insulator demonstrated by applying a many-body Wannier functions method to a charge model
T. Yamaguchi, K. Iwano, T. Miyamoto +5
We have applied a many-body Wannier functions method to theoretically calculate an excitonic optical conductivity spectrum and energy structure in a one-dimensional (1D) Mott insul…
Probing ultrafast spin-relaxation and precession dynamics in a cuprate Mott insulator with 7-fs optical pulses
T. Miyamoto, Y. Matsui, T. Terashige +10
A charge excitation in a two-dimensional Mott insulator is strongly coupled with the surrounding spins, which is observed as magnetic-polaron formations of doped carriers and a mag…
Terahertz radiation imaging of ferroelectric domain topology in room-temperature organic supramolecular ferroelectrics
M. Sotome, N. Kida, S. Horiuchi +1
We demonstrate a new method to detect ferroelectric domains in inside and surface regions of organic ferroelectrics by mapping out two orthogonally polarized terahertz waves radiat…
Visualization of ferroelectric domains in boracite using emission of terahertz radiation
Y. Kinoshita, N. Kida, M. Sotome +5
We report on the emission of terahertz radiation by irradiation of femtosecond laser pulses in non-centrosymmetric paraelectric and ferroelectric phases of CoBOI bor…
Terahertz radiation by optical rectification in a hydrogen-bonded organic molecular ferroelectric crystal, 2-phenylmalondialdehyde
W. Guan, N. Kida, M. Sotome +5
Terahertz radiation by optical rectification has been observed at room temperature in a hydrogen-bonded organic molecular ferroelectric crystal, 2-phenyl malondialdehyde (PhMDA). T…
Terahertz radiation induced by coherent phonon generation via impulsive stimulated Raman scattering in paratellurite
M. Sotome, N. Kida, R. Takeda +1
We report on the observation of terahertz radiation in a non-centrosymmetric insulating oxide, paratellurite (-TeO) by irradiation of a femtosecond laser pulse at room tempe…
Deconstructing the Hubbard Hamiltonian by Ultrafast Quantum Modulation Spectroscopy in Solid-state Mott Insulators
S. Kaiser, S. R. Clark, D. Nicoletti +8
Most available theories for correlated electron transport are based on the Hubbard Hamiltonian. In this effective theory, renormalized hopping and interaction parameters only impli…
