Formation and Evolution of Pair-Alfvén Shocks with PIC Simulations
John Daniel Riordan, Mark E. Dieckmann, Asaf Pe'er
We consider the recently discovered \emph{pair-Alfvén shock wave} occurring in collisionless electron-positron plasmas. We perform a series of Particle-In-Cell studies in one and t…
Change of a Weibel-type to an Alfvénic shock in pair plasma by upstream waves
M E Dieckmann, J D Riordan, A Pe'er
We examine with particle-in-cell (PIC) simulations how a parallel shock in pair plasma reacts to upstream waves, which are driven by escaping downstream particles. Initially, the s…
Pitch-Angle Diffusion and Bohm-type Approximations in Diffusive Shock Acceleration
John Daniel Riordan, Asaf Pe'er
The problem of accelerating cosmic rays is one of fundamental importance, particularly given the uncertainty in the conditions inside the acceleration sites. Here we examine Diffus…
TeraHz tuning of whispering gallery modes in a PDMS, stand-alone, stretchable microsphere
Ramgopal Madugani, Yong Yang, Jonathan M Ward +7
We report on tuning the optical whispering gallery modes in a poly dimethyl siloxane-based (PDMS) microsphere resonator by more than a THz. The PDMS microsphere system consists of…
