Phase-space measurements and decoherence for angular momentum systems
Dorje C. Brody, Eva-Maria Graefe, Rishindra Melanathuru
The monitoring of the three independent components of the angular momentum (or spin) of a quantum system by its environment that does not isolate any preferred orientation is model…

Decoherence from universal tomographic measurements
Dorje C. Brody, Rishindra Melanathuru
The decoherence phenomenon arising from an environmental monitoring of the state of a quantum system, as opposed to monitoring of a preferred observable, is worked out in detail us…

Phase-space measurements, decoherence and classicality
Dorje C. Brody, Eva-Maria Graefe, Rishindra Melanathuru
The emergence of classical behaviour in quantum theory is often ascribed to the interaction of a quantum system with its environment, which can be interpreted as environmental moni…
