... This question arises in the moment closure strategy initially introduced by Degond and Ringhofer in [13] in order to derive quantum hydrodynamic models from first principles. Let us briefly review this theory (for more details, one can refer to the reviews [12, 10]). The quest of macroscopic quantum ...

Time-dependent quantum circular billiard
... Billiards are convenient models for the study of classical and quantum dynamics of non-integrable systems. They have been extensively studied in both experimental [1] and theoretical contexts [2,3]. A remarkable feature of particle motion in billiards is the dependence of the dynamics on the geometr ...

Quantum technology: the second quantum revolution
... (v) Entanglement: the superposition principle applied to certain non-local correlations. If a correlation can be realized in two or more indistinguishable ways, the state of the system is a superposition of all such correlations simultaneously. (vi) Decoherence: what happens to quantum superposition ...
