Partition of unity with mixed quantum states
Hongyi Fan, Jun-hua Chen, Dehui Zhan +1
The completeness of quantum state space, is usually expressed as \sum_{m=0}^{\infty}|m><m|=1, where {|m>} is selected set of quantum states (basis). Density matrix |m><m| describes…
Uncertainty Relation of Functions for Kernel-based Transforms Obtained in Quantum Mechanics
Jun-Hua Chen, Hong-Yi Fan
In this paper, the generic uncertainty relation (UR) for kernel-based transformations (KT) of signals is derived. Instead of using the statistics approach as shown in the literatur…
Evolution of physical observables and entropy in laser process studied on the basis of Kraus-form solution of laser's master equation
Jun-Hua Chen, Hong-Yi Fan
Though laser physics began at 1960s, its entropy evolution has not been touched until very recently the Kraus-form solution of laser's master equation is reported (Ann. Phys. 334 (…
Quantum mechanical perspectives and generalization of the fractional Fourier Transformation
Jun-Hua Chen, Hong-Yi Fan
Fourier and fractional-Fourier transformations are widely used in theoretical physics. In this paper we make quantum perspectives and generalization for the fractional Fourier tran…
Conditions for plasma evolution to the\ strong general Woltjer-Taylor state
Jun-hua Chen, Hong-yi Fan
We find that the proof in the recent paper$\textsuperscript{\cite{14}}$ can not justify the authors' conclusion. We provide a real proof that any state will eventually evolves to t…
Entropy evolution law in a laser process
Jun-hua Chen, Hong-yi Fan
For the first time, we obtain the entropy variation law in a laser process after finding the Kraus operator of the master equation describing the laser process with the use of the…
