Journal ArticleDOI
A symplectic integration algorithm for separable Hamiltonian functions
Jeff Candy,Wojciech Rozmus +1 more
TL;DR: In this paper, the authors derive an algorithm to numerically integrate differential equations derivable from a separable Hamiltonian function, which preserves exactly the Poincare-Cartan integral invariants associated with the topology of the phase flow.
Journal ArticleDOI
Magnetic Reconnection and Plasma Dynamics in Two-Beam Laser-Solid Interactions
P. M. Nilson,Louise Willingale,Malte C. Kaluza,Christos Kamperidis,Stefano Minardi,Mingsheng Wei,P. Fernandes,M. M. Notley,S. Bandyopadhyay,Mark Sherlock,Robert Kingham,Michael Tatarakis,Zulfikar Najmudin,Wojciech Rozmus,Roger Evans,M. G. Haines,A. E. Dangor,K. Krushelnick +17 more
TL;DR: In this paper, the authors present measurements of a magnetic reconnection in a plasma created by two laser beams (1 ns pulse duration, 1 x 10(15) W cm(-2)) focused in close proximity on a planar solid target.
Journal ArticleDOI

TL;DR: The first direct measurements of total absorption of short laser pulses on solid targets in the ultrarelativistic regime are reported, showing an enhanced absorption at intensities above 10(20) W/cm(2), reaching 60% for near-normal incidence and 80%-90% for 45 degrees incidence.
Journal ArticleDOI
Theoretical model of x-ray scattering as a dense matter probe.
TL;DR: Analytical expressions for the dynamic structure factor, or form factor S(k,omega), which is the quantity describing the x-ray cross section from a dense plasma or a simple liquid, can be applied to describe scattering from either weakly coupled classical plasmas or degenerate electron liquids.

Magnetic reconnection and plasma dynamics in two beam laser-solid interactions
P. M. Nilson,Louise Willingale,Malte C. Kaluza,Christos Kamberides,Mingsheng Wei,Paulo Fernandes,Robert Kingham,Zulfikar Najmudin,M. G. Haines,Bucker Dangor,K. Krushelnick,Stefano Minardi,M. Tatarakis,M. M. Notley,S. Bandyopadhyay,Mark Sherlock,Roger Evans,Wojciech Rozmus +17 more
TL;DR: Measurements of a magnetic reconnection in a plasma created by two laser beams focused in close proximity on a planar solid target show Thomson scattering measurements from the reconnection layer are consistent with high electron temperatures in this region.
