Quantum states of a neutral massive fermion with an anomalous magnetic moment in an Aharonov–Casher field

Quantum states of a neutral massive fermion with an anomalous magnetic moment in an Aharonov–Casher field

The planar non-relativistic quantum dynamics of a neutral massive fermion with an anomalous magnetic moment (AMM) in the presence of the electric field of infinitely long and thin thread with a charge density distributed uniformly along it (an Aharonov--Casher field) is examined. The relevant Hamiltonian is singular and requires additional …
