Understanding how the combined geometric quantities of the curve and surface affect the quantum dynamics calls for an effective theory. Here, we delve into the effective Hamiltonian governing a quantum particle confined to a curve that lies on a curved surface. By categorizing the constraints, we derive the effective Hamiltonians for two distinct scenarios: one where the curve is encapsulated in the surface, and another where the curve is a narrow ridge on the surface. The surface’s geometry substantially influences the dynamics of the curve, with the gauge potential in the former case being proportional to the geodesic torsion, and the emerging surface geodesic potential in the latter case being determined by both the geodesic curvature and geodesic torsion. We apply both the Hamiltonians to model quantum dynamics in circles on a sphere and helices on a cylinder, analyzing how the effective potential varies with different geometric parameters.
