Hot Jupiters have proven themselves to be a rich class of exoplanets that test our theories of
planetary evolution and atmospheric dynamics under extreme conditions. Here, we present …

We report measurements of dynamo action in a new experimental set-up, named Fury,
based on the use of an anisotropic electrical conductivity. It consists of a copper rotor …

In the limit of large magnetic Reynolds numbers, it is shown that a smooth differential
rotation can lead to fast dynamo action, provided that the electrical conductivity or magnetic …

Hot Jupiter atmospheres may be subject to a thermoresistive instability where an increase in
the electrical conductivity due to ohmic heating results in runaway of the atmospheric …

In systems where the standard $\alpha $ effect is inoperative, one often explains the
existence of mean magnetic fields by invoking the 'incoherent $\alpha $ effect', which …

The evolution equations of anomalous magnetohydrodynamics are derived in the extreme
relativistic regime and contrasted with the treatment of hydromagnetic nonlinearities …

A mean‐field theory of the electrodynamics of a turbulent fluid is formulated under the
assumption that the molecular electric conductivity is correlated with the turbulent velocity …

We study the effects of conductivity variation on the Ponomarenko dynamo. Taking
monotonically increasing, decreasing and sinusoidally varying radial profiles, we study the …

We address magnetic-field generation by dynamo action in systems with inhomogeneous
electrical conductivity and magnetic permeability. More specifically, we first show that the …

Consequences of fluctuating microscopic conductivity in mean-field electrodynamics of
turbulent fluids are formulated and discussed. If the conductivity fluctuations are assumed to …
