We propose a simple situation in which the magnetic Aharonov–Bohm potential influences the values of the deficiency indices of the initial Schrödinger operator, so determining whether the particle interacts with the solenoid or not. Even with the particle excluded from the magnetic field, the number of self-adjoint extensions of the initial Hamiltonian depends on the magnetic flux. This is a new point of view of the Aharonov–Bohm effect. 
Semiclassical spectrum of the Dirichlet–Pauli operator on an annulus
This paper is devoted to the semiclassical analysis of the spectrum of the Dirichlet–Pauli operator on an annulus. We assume that the magnetic field is strictly positive and radial. We give an

The Aharonov–Bohm effect in a closed flux line
The Aharonov-Bohm (AB) effect was convincingly demonstrated using a microsized toroidal magnet but it is almost always explained using an infinitely-long solenoid or an infinitely-long flux line. The

The use of potential fields in fluid dynamics is retraced, ranging from classical potential theory to recent developments in this evergreen research field. The focus is centred on two major

Aharonov-Bohm Effect with $δ$--type Interaction
A quantum particle interacting with a thin solenoid and a magnetic flux is described by a five-parameter family of Hamilton operators, obtained via the method of self-adjoint extensions. One of the

Using the theory of self-adjoint extensions, we construct all the possible Hamiltonians describing the nonrelativistic Aharonov–Bohm effect. In general, the resulting Hamiltonians are not

It is presented, in the framework of nonrelativistic quantum mechanics, a justification of the usual Aharonov-Bohm hamiltonian (with solenoid of radius greater than zero). This is obtained by way of

It is shown that a satisfactory treatment of the Aharonov–Bohm problem requires no departure from the basic principles of ordinary quantum mechanics, a fact not entirely clear in the literature. The

TLDR
The observation of the absence of time delays associated with forces of the magnitude needed to explain the AB-phase shift for a macroscopic system is reported.

The Aharonov-Bohm effect has recently been questioned on theoretical and experimental grounds. Such discussins have suffered from ambiguities which resulted from their focusing on scattering states.
