Remarks on Quantum Differential Operators

In the course of writing the book [9] and various papers [10, 11, 12, 13, 14, 15, 16] we encountered many q-differential equations but were frustrated by a lack of understanding about natural forms for such equations. One has operators of the type qKP or qKdV for example but even there, expressing the resulting equations (even via Hirota type equations or in bilinear form) seemed curiously diff...

Controversy about Quantum Time Decay

Laser physics: Quantum controversy in action

Neural quantum controversy in sensory psychology.

processes underlying sensory discrimination. Simply stated, the question is whether, under a particular set of conditions, sensation is changed in a continuous or a discrete manner as the corresponding physical stimulus is continuously altered. Evidence on the issue is typically obtained in experiments on differential thresholds. Stevens (1) contends that "some 140" functions have been obtained...

Notes on quantum entanglement of local operators

This is an expanded version of the short report arXiv:1401.0539, where we studied the time evolution of (Renyi) entanglement entropies for the excited state defined by acting a given local operator on the ground state. In the present paper, we introduce (Renyi) entanglement entropies of given local operators which are defined by late time values of excesses of (Renyi) entanglement entropies. Th...
