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…
GWΓ + Bethe-Salpeter equation approach for photoabsorption spectra: Importance of self-consistent GWΓ calculations in small atomic systems
Riichi Kuwahara, Yoshifumi Noguchi, Kaoru Ohno
The self-consistent GWΓ method satisfies the Ward-Takahashi identity (i.e., the gauge invariance or the local charge continuity) for arbitrary energy () and momentum () t…
Quantum Nernst Effect in a Bismuth Single Crystal
Mari Matsuo, Akira Endo, Naomichi Hatano +3
We calculate the phonon-drag contribution to the transverse (Nernst) thermoelectric power in a bismuth single crystal subjected to a quantizing magnetic field. The calcula…
Analysis of scale-free networks based on a threshold graph with intrinsic vertex weights
Naoki Masuda, Hiroyoshi Miwa, Norio Konno
Many real networks are complex and have power-law vertex degree distribution, short diameter, and high clustering. We analyze the network model based on thresholding of the summed…
Transmission of severe acute respiratory syndrome in dynamical small-world networks
Naoki Masuda, Norio Konno, Kazuyuki Aihara
The outbreak of severe acute respiratory syndrome (SARS) is still threatening the world because of a possible resurgence. In the current situation that effective medical treatments…
