Dissipation, the irreversible loss of energy and coherence, from a microsystem is the result
of coupling to a much larger macrosystem (or reservoir) that is so large that one has no …

During recent years we could bear witness to an immense research activity, both in
experimental and theoretical physics, as well as in chemistry, aimed at understanding the …

This is the first book devoted to quantum state diffusion (QSD) and its applications to open
quantum systems and to the foundations of quantum mechanics. Recent experiments with …

We present the non-Markovian generalisation of the widely used stochastic Schrödinger
equation. Our result allows one to describe open quantum systems in terms of stochastic …

We formulate the conditions under which the dynamics of a continuously measured quantum
system becomes indistinguishable from that of the corresponding classical system. In …

First, we summarize the argument against deterministic nonlinear Schrodinger equations.
We recall that any such equation activates quantum nonlocality in the sense that that …

Numerical simulation of individual open quantum systems has proven advantages over
density operator computations. Quantum state diffusion with a moving basis (MQSD) …

Except for the universe, all quantum systems are open, and according to quantum state
diffusion theory, many systems localize to wavepackets in the neighbourhood of phase …

Classical dynamics is formulated as a Hamiltonian flow in phase space, while quantum
mechanics is formulated as unitary dynamics in Hilbert space. These different formulations …

The dynamical status of isolated quantum systems is unclear as conventional measures fail
to detect chaos in such systems. However, when quantum systems are subjected to …
