Beyond minimal coupling for charged scalars? Modified electrodynamics and London-penetration tests
F. Minotti, G. Modanese
We discuss an effective modification of the electromagnetic coupling for charged scalar condensates. The motivation is not an inconsistency of standard scalar QED, but a semiclassi…
A Structural Link Between the Bohm Quantum Potential and the Scalar Mode of Aharonov-Bohm Electrodynamics in a Bosonic Schrödinger Model
R. Pullano, G. Modanese
We discuss a formal and physical connection between the Bohm quantum potential and the scalar mode of the Aharonov-Bohm extension of electrodynamics. The analysis is motivated by t…
Quantum collapse, local conservation of charge, and possible experimental consequences
F. Minotti, G. Modanese
We investigate the possibility that idealized quantum state-reduction processes may produce a local violation of charge conservation. If this occurs, the corresponding electromagne…
Fluctuations in Aharonov-Bohm Electrodynamics
F. Minotti, G. Modanese
We consider the application of the Fluctuation Dissipation Theorem (FDT) to the electrodynamics of Aharonov-Bohm (ABE), which differs from Maxwell's in that it allows for local non…
Scalar-tensor gravity and Aharonov-Bohm electrodynamics with bosons: applications to superconductors
F. Minotti, G. Modanese
We study a scalar-tensor extension of gravity with two scalar fields coupled to the Aharonov-Bohm extension of electrodynamics, where the scalar mode is dy…
Do we need an alternative to local gauge coupling to electromagnetic fields?
F. Minotti, G. Modanese
The local gauge coupling through the recipe , that works so well with Dirac spinors in QED and in the gauge theories of the Standard Model…
