The physics of turbulent heating of low-beta GK plasmas was already summarised and discussed at length in section 2, so we need not repeat that discussion. The headline result is the clean separation between the Alfvénic cascade heating the electron…

Constraints on ion vs. electron heating by plasma turbulence at low b…

It is shown that in low-beta plasmas, such as the solar corona, some instances of the solar wind, the aurora, inner regions of accretion discs, their…

Form factors for $B$ to $Kll$ semileptonic decay from three-flavor …

We study the $B \to Kl^+l^-$ semileptonic decay process in three-flavor lattice QCD. We analyze several ensembles generated by the MILC collaboration…

Stochasticity from function - why the Bayesian brain may need no noise

An increasing body of evidence suggests that the trial-to-trial variability of spiking activity in the brain is not mere noise, but rather the reflec…

The origin of radio pulsar polarisation

Polarisation of radio pulsar profiles involves a number of poorly understood, intriguing phenomena, such as the existence of comparable amounts of or…

Polyakov loop renormalization with gradient flow

We propose to use the gradient flow for the renormalization of Polyakov loops in various representations. We study Polyakov loops in 2+1 flavor QCD u…
