摘要：

We introduce a new definition of local charge Q, supplementing with a frequency cutoff the existing definition for spatial dimension D = 1. In systems with an energy gap, Q is a sharp, if medium-dependent, quantum observable for any D. The charge of a particle measured by the Aharonov-Bohm (AB) effect is also sharp, but medium-independent. Inside a superconductor the Q of a quasiparticle is zero, while the AB charge is an odd multiple of e.
