Aharonov-Bohm effect for bound states in Kaluza-Klein theory

Using Kaluza-Klein theory we study the quantum mechanics of a scalar partic le in the background of a chiral cosmic string and of a magnetic cosmic str ing. We show that the wave functions and the energy spectra associated with the particle depend on the global features of those space-times. These dep endences represent the analogs of the well-known Aharonov-Bohm effect. This effect appears as the sum of two contributions, one of gravitational origi n and the other of electromagnetic origin.
