Weakly spin-dependent band structures of antiferromagnetic perovskite LaMO (M = Cr, Mn, Fe)
Takuya Okugawa, Kaoru Ohno, Yusuke Noda +1
We investigate spin-dependent electronic states of antiferromagnetic (AFM) lanthanum chromite (LaCrO), lanthanum manganite (LaMnO), and lanthanum ferrite (LaFeO) using…
Modulation of Nearly Free Electron States in Hydroxyl-Functionalized MXenes: A First-Principles Study
Jiaqi Zhou, Mohammad Khazaei, Ahmad Ranjbar +5
The transition metal carbides (namely MXenes) and their functionalized derivatives exhibit various physical and chemical characteristics and offer many potential applications in el…
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…
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…
