Solution of the Fokker-Planck equation with a logarithmic potential and mixed eigenvalue spectrum
Filippo Guarnieri, Woosok Moon, John Wettlaufer
Motivated by a problem in climate dynamics, we investigate the solution of a Bessel-like process with negative constant drift, described by a Fokker-Planck equation with a potentia…
On the possibility of helicity oscillations in the saturation of the Tayler instability
Alfio Bonanno, Filippo Guarnieri
Recent numerical results of current-driven instabilities at low magnetic Prandtl number and high Hartmann number support the possibility of a saturation state characterized by heli…
One-loop renormalization in a toy model of Horava-Lifshitz gravity
Dario Benedetti, Filippo Guarnieri
We present a one loop calculation in the context of Horava-Lifshitz gravity. Due to the complexity of the calculation in the full theory we focus here on the study of a toy model,…
Brans-Dicke theory in the local potential approximation
Dario Benedetti, Filippo Guarnieri
We study the Brans-Dicke theory with arbitrary potential within a functional renormalization group framework. Motivated by the asymptotic safety scenario of quantum gravity and by…
Universality and symmetry breaking in conformally reduced quantum gravity
Alfio Bonanno, Filippo Guarnieri
The scaling properties of quantum gravity are discussed by employing a class of proper-time regulators in the functional flow equation for the conformal factor within the formalism…
