Gravitational effects in a superconducting film struck by a laser pulse

Giovanni A. Ummarino, Antonio Gallerati

We study the local interaction of the gravitational field with a superfluid condensate. To this end, we exploit the Ginzburg-Landau formalism with generalized Maxwell fields. The a…

Interaction between macroscopic quantum systems and gravity

Antonio Gallerati, Giovanni Modanese, Giovanni Ummarino

We review experiments and theoretical models about the possible mutual interplay between the gravitational field and materials in the superconducting state or other macroscopic qua…

Superconductors and gravity

Antonio Gallerati, Giovanni Ummarino

We review and discuss some recent developments on the unconventional interaction between superconducting systems and the local gravitational field. While it is known that gravitati…

Superconductor in static gravitational, electric and magnetic fields with vortex lattice

Giovanni Ummarino, Antonio Gallerati

We estimate the conjectured interaction between the Earth gravitational field and a superconductor immersed in external, static electric and magnetic field. The latter is close to…

Possible alterations of local gravitational field inside a superconductor

G. A. Ummarino, A. Gallerati

We calculate the possible interaction between a superconductor and the static Earth's gravitational fields, making use of the gravito-Maxwell formalism combined with the time-depen…

Interaction between superconductors and weak gravitational field

Antonio Gallerati

We consider the interaction between the Earth's gravitational field and a superconductor in the fluctuation regime. Exploiting the weak field expansion formalism and using time dep…

Josephson AC effect induced by weak gravitational field

Giovanni Alberto Ummarino, Antonio Gallerati

In this paper we examine the possibility of a Josephson AC effect between two superconductors induced by the Earth's gravitational field, making use of the gravito-Maxwell formalis…

Exploiting weak field gravity-Maxwell symmetry in superconductive fluctuations regime

Giovanni Alberto Ummarino, Antonio Gallerati

We study the behaviour of a superconductor in a weak static gravitational field for temperatures slightly greater than its transition temperature (fluctuation regime). Making use o…

Superconductor in a weak static gravitational field

Giovanni Alberto Ummarino, Antonio Gallerati

We provide the detailed calculation of a general form for Maxwell and London equations that takes into account gravitational corrections in linear approximation. We determine the p…
