Universally valid reformulation of the Heisenberg uncertainty
... on every input state , where E A (⌬) stands for the spectral projection of A corresponding to interval ⌬. Otherwise, we consider apparatus A to measure observable A with some noise. In order to evaluate the noise, we need to describe the measuring process. The measuring interaction is supposed to ...

Particle Statistics Affects Quantum Decay and Fano Interference
... (a quantum wire), each with energy ϵ ¼ 0 [see Figs. 1(a) and 1(b)]. Thus, states j1i and j2i can decay by tunnelling to the common continuum given by the tight-binding lattice band of the quantum wire. The energy of the band spans the interval −2κ < E < 2κ, κ being the hopping rate between two adjac ...

A Quantum Version of The Spectral Decomposition Theorem of
... as mentioned in [2], the study of chaos based on QEH takes into account that classical limit may not exhibit chaotic behavior which would be a threat to Correspondence Principle (CP). In paper [25] we discuss and give an alternative way to study chaos in quantum systems based on fundamental grainine ...
