Two-dimensional transverse-field $XY$ model with the in-plane anisotropy and Dzyaloshinskii-Moriya interaction: Anisotropy-driven transition

Yoshihiro Nishiyama

The two-dimensional (2D) quantum spin-$S=1/2$ $XY$ model with the transverse-field $H$, in-plane-anisotropy ${\hat{I}}^3$, and Dzyaloshinskii-Moriya (DM) $D$ interactions was investigated b…
