TY  - JOUR
AB  - High intensity lasers can be used to generate shockwaves which have found applications in nuclear fusion, proton imaging, cancer therapies, and materials science. Collisionless electrostatic shocks are one type of shockwave widely studied for applications involving ion acceleration.  Here we show a novel mechanism for collisionlesselectrostatic shocks to heat small amounts of solid density matter to temperatures of  ∼ keV  in  tens  of  femtoseconds.   Unusually,  electrons  play  no  direct  role  in  the heating, and it is the ions which determine the heating rate.  Ions are heated due to  an  interplay  between  the  electric  field  of  the  shock,  the  local  density  increaseduring the passage of the shock, and collisions between different species of ion.  In simulations, these factors combine to produce rapid, localised heating of the lighter ion species.  Although the heated volume is modest, this would be one of the fastest heating mechanisms discovered if demonstrated in the laboratory.
