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.
