Entanglement entropy of $\alpha$-vacua in de Sitter space [PDF]
, 2014 We consider the entanglement entropy of a free massive scalar field in the one parameter family of $\alpha$-vacua in de Sitter space by using a method developed by Maldacena and Pimentel.

The open string membrane paradigm with external electromagnetic fields [PDF]
, 2011 We study the effective geometry felt by the fluctuations of open strings living on the worldvolume of probe D-branes in the presence of background electromagnetic fields.

Pick-up ion dynamics at the structured quasi-perpendicular shock [PDF]
, 1997 We study the pickup ion dynamics and mechanism of multiple reflection and acceleration at the structured quasi-perpendicular supercritical shock. The motion of the pickup ions in the shock is studied analytically and numerically using the test particle ...

Suspended liquid particle disturbance on laser-induced blast wave and low density distribution [PDF]
, 2017 The impurity effect of suspended liquid particles on the laser-induced gas breakdown was experimentally investigated in quiescent gas. The focus of this study is the investigation of the influence of the impurities on the shock wave structure as well as ...

Flow visualisation of a normal shock impinging over a rounded contour bump in a Mach 1.3 free-stream [PDF]
, 2016 An experimental study has been conducted to visualise the instantaneous streamwise and spanwise flow patterns of a normal shock wave impinging over a rounded contour bump in a Mach 1.3 free-stream.

On imploding cylindrical and spherical shock waves in a perfect gas [PDF]
, 2006 The problem of a cylindrically or spherically imploding and reflecting shock wave in a flow initially at rest is studied without the use of the strong-shock approximation.

The Transition Zone in Balmer-Dominated Shocks [PDF]
, 2007 We examine the structure of the post-shock region in supernova remnants (SNRs). The ``shock transition zone'' is set up by charge transfer and ionization events between atoms and ions, and has a width $\sim 10^{15}$ cm$^{-2}$ $n^{-1}_0$, where $n_0$ is ...

Nanoscale Molecular Dynamics Simulaton of Shock Compression of Silicon [PDF]
, 2005 We report results of molecular dynamics simulation of shock wave propagation in silicon in [100], [110], and [111] directions obtained using a classical environment-dependent interatomic potential (EDIP).

Shock wave initiation of the Ti5Si3 reaction in elemental powders [PDF]
, 1997 Elemental powder mixes were subjected to plane wave shock processing which reduced the initial porosity to essentially zero. Two powder mixes in a 5:3 Ti:Si atomic ratio were used: -325 mesh Ti and Si (

A Three-Flavor AdS/QCD Model with a Back-Reacted Geometry
, 2007 A fully back-reaction geometry model of AdS/QCD including the strange quark is described. We find that with the inclusion of the strange quark the impact on the metric is very small and the final predictions are changed only negligibly.Comment: 10 pages,
