In this paper the scattering theory for such open systems is considered. First it is assumed that a single maximal dissipative operator A D in a Hilbert space ${mathfrak H}$ is used to describe an open quantum system. In this case the minimal self-adjoint dilation $widetilde K$ of A D...
Substituting Eα and ψα into the eigenequation for the non-Hermitian Hamiltonian Hc+ΣR underlying an open quantum dot system [Hc+ΣR]ψα=Eαψα, keeping only the first-order terms of the small quantities, and taking into account the orthogonality of ψ0α, one has Δα+iγα...
We take the limit that 1/GN K 1 in order to enhance quantum effects due to bulk entanglement. In this case, the region LI will be given by the union of the whole left bath plus quantum system − L − and a small interval I in the right, flat space bath, as in figure 4. ...
To imitate an infinitely long system, we place an absorber on the right side. On the left side, the waveguide is closed with a metallic wall. Using Teflon (orange rectangles, 8 mm high) and metallic (dark gray rectangle, 11 mm high) scatterers, we create a complex scattering environment ...
Article Open access 22 June 2022 Introduction A significant fraction of the research activities in the field of high-resolution imaging involves the scattering lens1,2,3,4,5,6,7,8,9,10. This is due to the fact that the optical imaging system using scattering lens could provide a better re...
where all of the quantities are measured in the laboratory coordinate system where the surface is at rest. For backscattering (i.e., θ > 90°), the impact parameter is small and consequently screening corrections to the Rutherford cross section are small (L'Ecuyer et al., 1979). Screening...

It has to be stressed that, in contrast to the potential energy, the kinetic energy of a many-body system has distinctly different properties in the classical regime (Maxwellian), the quantum liquid, the crystal (Debye-like), the superfluid (Bose condensation), and for liquid 3He (Fermi-...

realization (photon detection or counting) system. An aperture larger than the typical van Cittert-Zernike single speckle limit can thus be useful where signal level was formerly insufficient, regardless of whether the detection method is analog or quantum-realized. Conversely the reduction of ...
