Excitations of a supersolid annular stripe phase in a
spin-orbital-angular-momentum-coupled spin-1 Bose-Einstein condensate
We present a theoretical study of the collective excitations of the supersolid annular stripe phase of a spin-orbital-angular-momentum-coupled (SOAM-coupled) spin-1 Bose-Einstein condensate. The annular stripe phase simultaneously breaks two continuous symmetries, namely rotational and $U(1)$ gauge symmetry, and is more probable in the condensates with a larger orbital angular momentum …
