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…

$Λ_c-N$ interaction from lattice QCD

We investigate the s-wave $\Lambda_c-N$ interaction for spin singlet systems($^1S_0$) using the HAL QCD method. In our lattice QCD simulations, we em…

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…

Bedforms in a turbulent stream.Part 1: Turbulent flow over topography

In the context of subaqueous ripple and dune formation, we present here a Reynolds averaged calculation of the turbulent flow over a topography. We p…

O(a^2) corrections to 1-loop matrix elements of 4-fermion operators w…

We calculate the corrections to the amputated Green's functions of 4-fermion operators, in 1-loop Lattice Perturbation theory. The novel aspect of ou…

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…

Lambda-nucleon force from lattice QCD

We study the $\Lambda$-nucleon ($\Lambda N$) force by using lattice QCD. The Bethe-Salpeter amplitude is calculated for the lowest scattering state o…
