Multilocal-realistic nonlinear dynamics of quantum collapse

A minimally nonlinear von Neumann equation for a Stern-Gerlach or Bell-type measuring apparatus, having a scalar product structure over the configuration space, i.e. a sum of locally acting terms, is shown to display a competition for survival between diagonal density matrix elements assigned to each detector combination, with a single winner randomly selected according to Born’s rule and the r...

Finite Temperature Collapse of a Bose Gas with Attractive Interactions

We study the mechanical stability of the weakly interacting Bose gas with attractive interactions, and construct a unified picture of the collapse valid from the low temperature condensed regime to the high temperature classical regime. As we show, the non-condensed particles play a crucial role in determining the region of stability, even providing a mechanism for collapse in the non-condensed...

Collapse of a Bose Condensate with Attractive Interactions

We examine the Gross-Pitaevskii (GP) model for Bose-Einstein condensates in parabolic traps with attractive interactions. The decay of metastable condensates is investigated by applying the instanton formalism to the GP field theory. Employing various dynamical trial states, we derive within a coherent state path integral approach a collective coordinate description in terms of the condensate r...

Analysis and synthesis of attractive quantum Markovian dynamics

We propose a general framework for investigating a large class of stabilization problems in Markovian quantum systems. Building on the notions of invariant and attractive quantum subsystem, we characterize attractive subspaces by exploring the structure of the invariant sets for the dynamics. Our general analysis results are exploited to assess the ability of open-loop Hamiltonian and output-fe...

Quantum mechanical Liouville model with attractive potential

We study the quantum mechanical Liouville model with attractive potential which is obtained by Hamiltonian symmetry reduction from the system of a free particle on SL(2,RI ). The classical reduced system consists of a pair of Liouville subsystems which are ‘glued together’ in such a way that the singularity of the Hamiltonian flow is regularized. It is shown that the quantum theory of this redu...
