WebThis chapter indicates briefly the possibility of extending the phase approach to the case of scattering on nonlocal potentials. The chapter recalls that nonlocal potentials play a role … Web12 Apr 2024 · When a dyon encircles an infinitely-long solenoid enclosing uniform electric and magnetic fields, its wave function accumulates a duality-invariant quantum phase, which is topological because it depends on a winding number and is nonlocal because the enclosed fields act on the dyon in regions where these fields vanish. Here, we derive this …
