• ## Long range interactions in metallic systems

In a classical plasma one normally expects that correlations are short ranged -- due to Debye screening. In quantum mechanics the situation is more complicated we show here how long-ranged interaction are generated in an electron plasma in a way that is reminiscent of van der Waals interaction in $$1/r^6$$
