Repeatedly readable state, spontaneous collapse, and quantum/classical boundary
Xiao-Fu Peng, Yu-Hang Luo, Jiang Zhu +5
We propose a model to identify the quantum/classical boundary. The model introduces a spontaneous collapse of state superposition: $\frac{d}{dt} ρ_{ij} =-\frac{i}{\hbar}[H,ρ]_{ij}-…

Extraordinary spin density and energy back-flow under interference
Zhen-Lai Wang, Dan-Dan Lian, Xiang-Song Chen
A novel phenomenon was reported recently that the "local optical spin density" based on Poynting vector might be counter-intuitively opposite to the integrated spin orientation whi…
