Abstarct: Resently the AdS/CFT correspondence has been generalized to the descxription of some
non-relativistic strongly coupled systems.In this research, studied Schwinger Effect in non
relativistic vacuum and analyze electrostatic potentials by using AdS/CFT and utilized
the string theory and AdS/CFT correspondence.Such computing , significantly help us
to understanding the using vest implementation of AdS/CFT correspondence. For this
purpose the open string in the non-relativistic background be considered. Dual of this
problem,is the quark and anti quark in the non-relativistic vacuum space with zero tem
perature . For studing Schwinger Effect in non-relativistic vacuum, We consider Lifshits
and HyperScaling metrics in which there is the dynamics parameter z in the Lifshitz geom
etry and we find that if it increases, then width and hight of barrier potential decrease. In
HyperScaling metric, there is another parameter, HyperScaling , that if it increases, then
width and hight of barrier potential increase. Then the resulting critical-field completely
agrees with the DBI result. We also finit-temprature case and the temperature-dependent
critical-field also agrees with the DBI result.
