Quantum Singwi-Tosi-Land-Sjoelander approach for interacting inhomogeneous systems under electromagnetic fields: Comparison with exact results
Taichi Kosugi, Yu-ichiro Matsushita
For inhomogeneous interacting electronic systems under a time-dependent electromagnetic perturbation, we derive the linear equation for response functions in a quantum mechanical m…
Periodicity-free unfolding method of electronic energy spectra: Application to twisted bilayer graphene
Taichi Kosugi, Hirofumi Nishi, Yasuyuki Kato +1
We propose a novel periodicity-free unfolding method of the electronic energy spectra. Our new method solves a serious problem that calculated electronic band structure strongly de…
Unfolding energy spectra of multi-periodicity materials
Yu-ichiro Matsushita, Hirofumi Nishi, Jun-ichi Iwata +2
We propose a new unfolding scheme to analyze energy spectra of complex large-scale systems which are inherently of multi-periodicity. Considering twisted bilayer graphene (tBLG) as…
