Linear and nonlinear optical responses in the chiral multifold semimetal BeAu: A quantum-geometric perspective
Babu Baijnath Prasad, Taisuke Ozaki
Chiral topological semimetals provide a natural platform for exploring how multifold band topology and quantum geometry manifest in optical and photovoltaic responses. BeAu is a ch…
Closest Wannier functions to a given set of localized orbitals
Taisuke Ozaki
A non-iterative method is presented to calculate the closest Wannier functions (CWFs) to a given set of localized guiding functions, such as atomic orbitals, hybrid atomic orbitals…
Electronic band structure change with structural transition of buckled AuX monolayers induced by strain
Masahiro Fukuda, Taisuke Ozaki
This study investigates the strain-induced structural transitions of and the changes in electronic band structures of AuX (X=S, Se, Te, Si, Ge) and AuS…
Methods for constructing parameter-dependent flat band lattices
Toshitaka Ogata, Mitsuaki Kawamura, Taisuke Ozaki
We present two methods for constructing a flat band (FB) system having a flat energy dispersion over the entire Brillouin zone within tight-binding model, where the resulting Hamil…
Densest binary sphere packings and phase diagram : revisited
Ryotaro Koshoji, Mitsuaki Kawamura, Masahiro Fukuda +1
We revisit the densest binary sphere packings (DBSP) under the periodic boundary conditions and present an updated phase diagram, including newly found 12 putative densest structur…
First-principles study on the stability and electronic structure of monolayer GaSe with trigonal-antiprismatic structure
Hirokazu Nitta, Takahiro Yonezawa, Antoine Fleurence +2
The structural stability and electronic states of GaSe monolayer with trigonal-antiprismatic (AP) structure, which is a recently discovered new polymorph, were studied by first-pri…
