Magic numbers for vibrational frequency of charged particles on a sphere
Shota Ono
Finding minimum energy distribution of charges on a sphere is known as the Thomson problem. Here, we study the vibrational properties of the charges in the lowest energy st…
Theory of dynamical stability for two- and three-dimensional Lennard-Jones crystals
Shota Ono, Tasuku Ito
The dynamical stability of three-dimensional (3D) Lennard-Jones (LJ) crystals has been studied for many years. The face-centered-cubic and hexagonal close packed structures are dyn…
Anomalous energy shift of laterally confined two-dimensional excitons
Shota Ono, Tomohiro Ogura
We theoretically investigate the energy of the ground state exciton confined to two-dimensional (2D) monolayers with circular shape. Within an effective mass approach employing a n…
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…
Combined impact of entropy and carrier delocalization on charge transfer exciton dissociation at the donor-acceptor interface
Shota Ono, Kaoru Ohno
Several models of the charge transfer exciton (CTE) have been proposed to explain its dissociation at the donor-acceptor (DA) interface. However, the underlying physics is still un…
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…
