Floquet topological superconductivity induced by chiral many-body interactions
Sota Kitamura, Hideo Aoki
We study how a -wave superconductivity is changed when illuminated by circularly-polarised light (CPL) in the repulsive Hubbard model in the strong-coupling regime. We adopt the…

Topologically Protected Doubling of Tilted Dirac Fermions in Two Dimensions
Tohru Kawarabayashi, Hideo Aoki, Yasuhiro Hatsugai
The doubling of massless Dirac fermions on two-dimensional lattices is theoretically studied. It has been shown that the doubling of massless Dirac fermions on a lattice with broke…

High-modulation-efficiency InGaAsP/Si hybrid MOS optical modulator with Mach-Zehnder interferometer
Jae-Hoon Han, Frederic Boeuf, Shinichi Takagi +1
A high-modulation-efficiency optical modulator integrated on silicon (Si) is a key enabler for low-power and high-capacity optical interconnects. However, Si-based optical modulato…
