New Structures in the Theory of the Laser Model
F. Bagarello, G. L. Sewell
In a recent article, Alli and Sewell formulated a new version of the Dicke-Hepp-Lieb laser model in terms of quantum dynamical semigroups, and thereby extended the macroscopic pict…
On the Mathematical Theory of Superfluidity
Geoffrey L. Sewell, Walter F. Wreszinski
We provide a general operator algebraic formulation of superfluidity in Bose systems, with the aim of investigating the relationships of this phenomenon both to off-diagonal long r…
On Order, Disorder and Coherence
Geoffrey Sewell
We provide a brief survey of quantum statistical characterisations of order, disorder and coherence in systems of many degrees of freedom. Here, order and coherence are described i…
Can the Quantum Measurement Problem be resolved within the framework of Schroedinger Dynamics and Quantum Probability?
Geoffrey Sewell
We provide an affirmative answer to the question posed in the title. Our argument is based on a treatment of the Schroedinger dynamics of the composite of a quantum microsystem, S,…
On Connections between the Quantum and Hydrodynamical Pictures of Matter
Geoffrey Sewell
We present a general, model-independent, quantum statistical treatment of the connection between the quantum and hydrodynamical pictures of reservoir driven macroscopic systems. Th…
Can the Quantum Measurement Problem be resolved within the framework of Schroedinger Dynamics?
Geoffrey Sewell
We formulate the dynamics of the generic quantum system S_{c} comprising a microsystem S and a macroscopic measuring instrument I, whose pointer positions are represented by orthog…
