Career Summary

Biography

David Pontin obtained his PhD from The University of St Andrews in 2004. He subsequently took up a postdoctoral position at the University of Waikato (New Zealand) before moving to a Research Scientist position in the Space Science Centre at the University of New Hampshire (USA). From 2007 to 2019 he worked at the University of Dundee in Scotland, at levels from Lecturer to Professor in Applied Mathematics. In October 2019 he joined the Physics Department in Newcastle. His research interests include mathematical and computational modelling of astrophysical plasmas and in 2011 he was awarded a Philip Leverhulme Prize for Astronomy and Astrophysics.

Aims. Our aim is to investigate the resistive relaxation of a magnetic loop that contains braided magnetic flux but no net current or helicity. The loop is subject to line-tied boundary conditions. We investigate the dynamical processes that occur during this relaxation, in particular the magnetic reconnection that occurs, and discuss the nature of the final equilibrium. Methods. The three-dimensional evolution of a braided magnetic field is followed in a series of resistive MHD simulations. Results. It is found that, following an instability within the loop, a myriad of thin current layers forms, via a cascade-like process. This cascade becomes more developed and continues for a longer period of time for higher magnetic Reynolds number. During the cascade, magnetic flux is reconnected multiple times, with the level of this "multiple reconnection" positively correlated with the magnetic Reynolds number. Eventually the system evolves into a state with no more small-scale current layers. This final state is found to approximate a non-linear force-free field consisting of two flux tubes of oppositely-signed twist embedded in a uniform background field. © 2010 ESO.

We discuss the properties of braided magnetic fields, in particular with regard to their relaxation towards equilibrium both in the absence and presence of finite plasma resistivity. We consider a model magnetic field in which a subset of field lines are braided in the mathematical sense (in the form of a pigtail braid), and stretch between two perfectly conducting plates. An ideal relaxation yields an approximate force-free equilibrium without thin current sheets. However, in the presence of a finite resistivity the field spontaneously develops thin (but finite) current layers. Subsequently, the system undergoes a fast relaxation on an Alfvénic timescale via a myriad of thin current layers. The current layer structure becomes increasingly complex, and is increasingly long-lived, for higher magnetic Reynolds numbers. The effect of the resistive relaxation is to unbraid the magnetic field, that is to significantly simplify the mapping of field lines between the end plates. This process involves magnetic flux being reconnected multiple times. The final state of the resistive relaxation approximates a non-linear force-free field, implying the presence of additional constraints beyond the magnetic helicity on the relaxation process. The 'topological dissipation' hypothesis, which proposes to explain the heating of the solar corona via braiding of the coronal field by photospheric motions, is one of the most controversial ideas of solar physics. We therefore consider in some detail the relevance of our results to this debate. © 2013 The Authors.

Magnetic reconnection at a three-dimensional null point is the natural extension of the familiar two-dimensional X-point reconnection. Three dimensional null points are found in abundance in the solar corona, where they are thought to be an important feature with regards to the coronal heating problem. A model is set up here for reconnection at a 3D magnetic null point, by solving the kinematic, steady, resistive MHD equations in its vicinity. A steady magnetic field is assumed, as well as the existence of a localised diffusion region surrounding the null point. Particular attention is focused on the way that the magnetic flux changes its connections as a result of the reconnection process. The nature of the flows and the reconnection is found to be fundamentally different depending on the orientation of the electric current.
