Sandpiles and superconductors: dual variational formulations for critical-state problems
John W. Barrett, Leonid Prigozhin
Similar evolutionary variational inequalities appear as convenient formulations for continuous models for sandpile growth, magnetization of type-II superconductors, and evolution o…
Magnetised plasma turbulence in clusters of galaxies
A. A. Schekochihin, S. C. Cowley, R. M. Kulsrud +2
Cluster plasmas are magnetised already at very low magnetic field strength. Low collisionality implies that conservation of the first adiabatic invariant results in an anisotropic…
Semiclassical strings and AdS/CFT
A. A. Tseytlin
We discuss AdS/CFT duality in the sector of ``semiclassical'' string states with large quantum numbers. We review the coherent-state effective action approach, in which similar 2d…
Fast and slow nonlinear tearing mode reconnection
N. F. Loureiro, S. C. Cowley, W. D. Dorland +2
This is a brief account of our numerical study of the tearing mode reconnection. We demonstrate two main points. First, we show that, given sufficiently small resistivity, the Ruth…
Linear line polarimetry modelling of pre-main sequence stars
Jorick S. Vink, J. E. Drew, T. J. Harries +1
We present emission line polarimetry data and modelling relevant to the circumstellar geometry and kinematics around pre-main sequence stars. For a sample of both Herbig Ae/Be star…
Toeplitz Determinants From Compatibility Conditions
E. Basor, Y. Chen
In this paper we show, how a straightforward and natural application of a pair of fundamental identities valid for polynomials orthogonal over the unit circle, can be used to calcu…
