Macroscopically distinguishable superposition in infinitely many degrees of freedom
J. Fransson, B. C. Sanders, A. P. Sowa
We investigate the concept of macroscopically distinguishable superpositions within an infinite array of boson sites. Our approach is rigorous within the frame of Hilbert space the…

Nonlocal coherent states in an infinite array of boson sites
A. Sowa, J. Fransson
A regular coherent state (CS) is a special type of quantum state for boson particles placed in a single site. The defining feature of the CS is that it is an eigenmode of the annih…
