Autor: Amjad Ali, G. Shabbir Naz, M. Saleem Shahzad, M. H. Nasim, Aman-ur-Rehman, Rukhsana Kouser

Publikováno v: High Energy Density Physics. 26:48-55

The energy states of the bound electrons in high energy density systems (HEDS) are significantly affected due to the electric field of the neighboring ions. Due to this effect bound electrons require less energy to get themselves free and move into t

Publikováno v: High Energy Density Physics. 3:371-378

Extreme states of matter such as Warm Dense Matter “WDM” and Dense Strongly Coupled Plasmas “DSCP” play a key role in many high energy density experiments, however, creating WDM and DSCP in a manner that can be quantified is not readily feasi
