High-order quantum back-reaction and quantum cosmology with a positive cosmological constant
High-order quantum back-reaction quantum cosmology
2010/12/27
When quantum back-reaction by fluctuations, correlations and higher moments of a state becomes strong, semiclassical quantum mechanics resembles a dynamical system with a high-dimensional phase space....
