i was reading Random Phase Approximation and encouter with dielectric function(adsbygoogle = window.adsbygoogle || []).push({});

ε(q,ω)= 1- v(q) ∏(q,ω)

where v(q) is coulumb potential and ∏(q,ω) is density-density correlation function without coulumb interaction

now i do not understand this dielctric function can any one explain it physically for me?????

thanks in advance :)
