Quantum Black Noise and Generalized Quantum Stochastic Equations

چکیده
A notion of quantum black noise is considered. Quantum black noise is an analogue of quantum white noise but it acts in a Fock space with indefinite metric. Quantum white noise describes the leading term in the stochastic limit approximation to quantum dynamics while quantum black noise describes corrections to the leading term. We obtain and study generalized quantum stochastic equations describing corrections to the stochastic limit which include quantum black noise.

Quantum Multipole Noise and Generalized Quantum Stochastic Equations
A notion of quantum multipole (in particular, dipole) noise is considered. Quantum dipole noise is an analogue of quantum white noise but it acts in a Fock space with indefinite metric. Quantum white noise describes the leading term in the stochastic limit approximation to quantum dynamics while quantum multipole noise describes corrections to the leading term. We obtain and study generalized q...
متن کاملModulation Response and Relative Intensity Noise Spectra in Quantum Cascade Lasers
Static properties, relatively intensity noise and intensity modulation response in quantum cascade lasers (QCLs) studied theoretically in this paper. The present rate equations model consists of three equations for the electrons density in the conduction band and one equation for photons density in cavity length. Two equations were derived to calculate the noise and modulation response. Calcula...
متن کاملA unified stochastic formulation of dissipative quantum dynamics. I. Generalized hierarchical equations.
We extend a standard stochastic theory to study open quantum systems coupled to a generic quantum environment. We exemplify the general framework by studying a two-level quantum system coupled bilinearly to the three fundamental classes of non-interacting particles: bosons, fermions, and spins. In this unified stochastic approach, the generalized stochastic Liouville equation (SLE) formally cap...

In this research, the dispersion properties of magneto-acoustic waves in a plasma in the presence of quantum effects are studied. For this purpose, we employ a system of quantum fluid equations and Maxwell equations to derive a generalized dispersion relation. Our analytical results show that the wave frequency is modified by quantum corrections. Also, numerical estimations reveal that the effe...

We consider a simple quantum system subjected to a classical random force. Under certain conditions it is shown that the noise-averaged Wigner function of the system follows an integro-differential stochastic Liouville equation. In the simple case of polynomial noise-couplings this equation reduces to a generalized Fokker-Planck form. With nonlinear noise injection new " quantum diffusion " ter...
