Dynamical stability and low-temperature lattice specific heat of one-dimensional fullerene polymers
Atsushi Shimizu, Shota Ono
We theoretically investigate the dynamical stability of one-dimensional fullerene polymers by computing the phonon dispersion relations within the atomistic approach. We find that…
Thermalization in simple metals: The role of electron-phonon and phonon-phonon scatterings
Shota Ono
We study the electron and phonon thermalization in simple metals excited by a laser pulse. The thermalization is investigated numerically by solving the Boltzmann transport equatio…
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…
