Resumming the large-N approximation for time evolving quantum systems
Bogdan Mihaila, Fred Cooper, John F. Dawson
In this paper we discuss two methods of resumming the leading and next to leading order in 1/N diagrams for the quartic O(N) model. These two approaches have the property that they…

Exact and approximate dynamics of the quantum mechanical O(N) model
Bogdan Mihaila, Tara Athan, Fred Cooper +2
We study a quantum dynamical system of N, O(N) symmetric, nonlinear oscillators as a toy model to investigate the systematics of a 1/N expansion. The closed time path (CTP) formali…
