Super-entropic black hole with Immirzi hair
Simon Boudet, Flavio Bombacigno, Giovanni Montani +1
In the context of f(R) generalizations to the Holst action, endowed with a dynamical Immirzi field, we derive an analytic solution describing asymptotically Anti-de Sitter black ho…
Contributions to the linear and non-linear theory of the beam-plasma interaction
Nakia Carlevaro, Matteo Del Prete, Giovanni Montani +1
We focus our attention on some relevant aspects of the beam-plasma instability in order to refine some features of the linear and non-linear dynamics. After a re-analysis of the Po…
Resonance overlap and non-linear features of the beam-plasma system
Nakia Carlevaro, Giovanni Montani, Matteo Valerio Falessi
The beam-plasma instability can be addressed as a reduced model in several contexts of plasma physics, from space to fusion plasma. In this paper, we review and refine some non-lin…
Contribution to the angular momentum transport paradigm for accretion disks
Giovanni Montani, Nakia Carlevaro
We analyze the stationary configuration of a thin axisymmetric stellar accretion disk, neglecting non-linear terms in the plasma poloidal velocity components. We set up the Grad-Sh…
Polymer dynamics of isotropic universe in Ashtekar and in volume variables
Eleonora Giovannetti, Gabriele Barca, Federico Mandini +1
We analyze the semiclassical and quantum polymer dynamics of the isotropic Universe in terms of both the standard Ashtekar-Barbero-Immirzi connection and its conjugate momentum and…
Quantum dynamics of the corner of the Bianchi IX model in WKB approximation
Roberta Chiovoloni, Giovanni Montani, Valerio Cascioli
In this paper we analyse the Bianchi IX Universe dynamics within the corner region associated to the potential term which the spatial curvature induces in the Minisuperspace. The s…
