Use the Rotating Frame node to add rotating frame contribution to the Hamiltonian.

Select x-axis, y-axis, z-axis or User defined from the drop down menu (default: z-axis). For user defined, enter the Rotation axis base point (unit: m, default: the origin) and the Rotation axis direction (dimensionless, default: +z direction).

The axis of rotation is fixed in the out-of-plane direction. Enter the Rotation axis base point (unit: m, default: the origin).

Enter the rotation speed in the input field (unit: rad/s, default: 0).
