Time-dependent entropy of simple quantum model systems
Information-theoretic entropy measures are useful tools for quantifying the spreading of quantum states in phase space. In the present paper, we compare the time evolution of the joint entropy for three simple quantum systems: sid a free Gaussian wave packet, siid a wave packet in a monochromatic electromagnetic field, and siiid a wave packet tunneling through a d barrier. As initial condition ...
متن کاملComment on “Replay to Comment on Time-dependent Quasi-Hermitian Hamiltonians and the Unitary Quantum Evolution”
I point out that if one defines the operator UR(t) as done by M. Znojil in his reply [arXiv:0711.0514v1] to my comment [arXiv:0711.0137v1] and also accepts the validity of the defining relation of UR(t) as given in his paper [arXiv:0710.5653v1], one finds that the time-evolution of the associated quantum system is not governed by the Schrödinger equation for the Hamiltonian operator H but an op...

متن کاملOn the Monotone Behavior of Time Dependent Entropy of Order alpha
In this paper we study some monotone behavior of the residual (past) entropy of order . We prove that, under some relation between the hazard rates (reversed hazard rates) of two distributions functions F and G, when the residual (past) entropy of order of F is decreasing (increasing) then the residual (past) entropy of G is decreasing (increasing). Using this, several conclusions regarding mo...
متن کاملAnalysis on Behaviors of Controlled Quantum Systems via Quantum Entropy
In this paper, we investigate the essential properties of finite dimensional measurement-based quantum feedback control systems using a kind of quantum entropy, or socalled linear entropy. We show how the terms appear in the stochastic master equation affect the purity of the conditional density matrix of the system, and clarify a limitation of control action via Hamiltonian. Moreover, applying...
