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…
Instability of supersymmetric black holes via quantum phase transitions
Andrés Anabalón, Dumitru Astefanesei, Antonio Gallerati +1
In this paper we prove that the four-dimensional hyperbolic supersymmetric black holes can be unstable in the canonical ensemble. To this end, we work with an infinite class of $\,…
Supersymmetric theories and graphene
Antonio Gallerati
We discuss a 1+2 dimensional model with unconventional supersymmetry at the boundary of an AdS, \,-extended supergravity. The resulting features of the supersymm…
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…
Negative-curvature spacetime solutions for graphene
Antonio Gallerati
We provide a detailed analysis of the electronic properties of graphene-like materials with charge carriers living on a curved substrate, focusing in particular on constant negativ…
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…
