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…
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…
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…
A new theory of tensor-scalar gravity coupled to Aharonov-Bohm electrodynamics
F. Minotti, G. Modanese
Tensor-scalar theories of gravitation are commonly employed as extensions of General Relativity that allow to describe a much wider phenomenology. They are also naturally generated…
Generalized local charge conservation in many-body quantum mechanics
F. Minotti, G. Modanese
In the framework of the quantum theory of many-particle systems, we study the compatibility of approximated Non-Equilibrium Green Functions (NEGFs) and of approximated solutions of…
