Orbital Angular Momentum and Spectral Flow in Two Dimensional Chiral Superfluids

Yasuhiro Tada, Wenxing Nie, Masaki Oshikawa

We study the orbital angular momentum (OAM) $L_z$ in two dimensional chiral $(p_x+i{p}_y{)}^{\nu }$-wave superfluids (SF) of $N$ fermions on a disc at zero temperature, in terms of spectral…
