| Research Abstract |
We focus on spectroscopic properties of low-dimensional strongly correlated electron systems, which can detect dynamics of spin, charge, orbital, and lattice degrees of freedom, in order to make a progress on our understanding of various quantum phenomena appearing in the systems. We use numerical techniques such as exact diagonalization and dynamical density-matrix renormalization group. We find various spectroscopic properties in the systems, for example, photoexcitation the relaxation dynamics of Mott insulators coupled to phonon, spin dynamics in low-dimensional spin systems coupled to phonon, resonant inelastic x-ray scattering in itinerant antiferromagnets and cuprate superconductors, magnetic Raman scattering in organic systems with triangular lattice. The obtained results are published in many journals.
