Quantum geometry in low-energy linear and nonlinear optical responses of magnetic Rashba semiconductor (Ge,Mn)Te
Tsubasa Takagi, Hikaru Watanabe, Ryutaro Yoshimi +7
Quantum geometry appears as a key factor in understanding the optical properties of quantum materials, with the anticipation on diverging or quantized responses near the Dirac and…
Emergence of ferroelectric topological insulator as verified by quantum Hall effect of surface states in (Sn,Pb,In)Te films
Ryutaro Yoshimi, Ryosuke Kurihara, Yoshihiro Okamura +9
Emergent phenomena arising from nontrivial band structures based on topology and symmetry have been attracting keen interest in contemporary condensed-matter physics. Materials suc…
Enhanced photogalvanic current in topological insulators via Fermi energy tuning
K. N. Okada, N. Ogawa, R. Yoshimi +4
We achieve the enhancement of circular photogalvanic effect arising from the photo-injection of spins in topological insulator thin films by tuning the Fermi level (). A…
Phase-change memory function of correlated electrons in organic conductors
H. Oike, F. Kagawa, N. Ogawa +4
Phase-change memory (PCM), a promising candidate for next-generation non-volatile memories, exploits quenched glassy and thermodynamically stable crystalline states as reversibly s…
