Nonequilibrium phonon dynamics beyond the quasiequilibrium approach
Shota Ono
The description of nonequilibrium states of solids in a simplified manner is a challenge in the field of ultrafast dynamics. Here, the phonon thermalization in solids through the t…
Effect of one-dimensional superlattice potentials on the band gap of two-dimensional materials
Shota Ono
Using the tight-binding approach, we analyze the effect of a one-dimensional superlattice (1DSL) potential on the electronic structure of black phosphorene and transition metal dic…
A simple derivation of the exact quasiparticle theory and its extension to arbitrary initial excited eigenstates
Kaoru Ohno, Shota Ono, Tomoharu Isobe
The quasiparticle (QP) energies, which are minus of the energies required by removing or produced by adding one electron from/to the system, corresponding to the photoemission or i…
Linear response theory for electron-hole pair kinetics: exciton formation
Shota Ono
A linear response theory for electron-hole pair density is developed, which constitutes a new theoretical method, and a definition of exciton density in a first-principles context…
Minimal model for charge transfer excitons at the dielectric interface
Shota Ono, Kaoru Ohno
Theoretical description of the charge transfer (CT) exciton across the donor-acceptor interface without the use of a completely localized hole (or electron) is a challenge in the f…
