Query: Bulk-edge correspondence in topological pumping   The topological pumping [1-3] is revisited from a view point of the bulk-edge
correspondence. Shift of the center of mass (CM) as a pumped charge is
explicitly given by the Berry connection in time direction. We show that
observed pumping is due to the bulk, but its quantization is guaranteed by
singular motion of the CM caused by edge states. This is the bulk-edge
correspondence in the topological pumping. A gauge invariant form of the pumped
charge is proposed by the temporal gauge and is used to establish this
bulk-edge correspondence.
