A dynamical model for the collapse of the wave function in a quantum measurement process is proposed by considering the interaction of a quantum system (spin -12) with a macroscopic quantum apparatus interacting with an environment in a dissipative manner. The dissipative interaction leads to...

The nucleation kinetics of a binary mixture is studied using a Gibbs free energy function that we have recently used to obtain a range of generic phase diagrams when liquid mixtures are cooled to solid state. This allows us to compute analytically all the quantities related to the free energy...
