TL;DR: In this article, the basic theoretical concepts in particle acceleration, with particular emphasis on processes likely to occur in regions of magnetic reconnection, are reviewed, including detailed studies of reconnection in three-dimensional magnetic field configurations, and stochastic acceleration in a turbulent environment.

TL;DR: In this article, the authors used numerical simulations to investigate the heating process of solar coronal plasma to millions of degrees, with energy release occurring in the nonlinear phase due to fast magnetic reconnection.

TL;DR: In this paper, the authors investigate the nonlinear aspects of magnetic relaxation on a current loop with zero net axial current and investigate the dynamical processes leading to the establishment of a relaxed state.

TL;DR: A review of recent observational findings, large and small-scale numerical modelling of physical processes occurring in the solar atmosphere and other aspects which may affect our understanding of the proposed heating mechanisms is presented in this paper.
