THE CASIMIR EFFECT

Two colleagues of him, Verwey and Overbeek, were studying experimentally colloidal suspensions. It seems that a simple model based on the van der Wa ...

Quantum and Classical Correlations in Quantum Brownian Motion

Our analysis will be split into two parts. In the first part we will show that surprisingly, quantum Brownian motion doe ...
