A bstract For any state in a D-dimensional Hilbert space with a choice of basis, one can define a discrete version of the Wigner function—a quasi-probability distribution which …
Der Autor präsentiert eine neue Theorie der Reduktion physikalischer Theorien, die nicht einen ein für alle Mal verbindlichen, allgemeinen Reduktionsbegriff zugrunde legt, sondern …

The relative entropy of entanglement ER is defined as the distance of a multipartite quantum state from the set of separable states as measured by the quantum relative entropy. We …
A general attenuator Φ λ, σ is a bosonic quantum channel that acts by combining the input with a fixed environment state σ in a beam splitter of transmissivity λ. If σ is a thermal state …

Abstract The Generalized Quantum Langevin Equation (GLE) approach to the quantum transport of many electron systems is developed to study the high electric field transport …

We treat a PT-symmetric directional coupler with Kerr nonlinearity in both the single-mode waveguides. We investigate the quantum propagation of a coherent state through this …
On the basis of Tani's formalism for nonlinear response, a closed-form expression of the field- dependent dc conductivity is introduced. The field-dependent dc conductivity of electron …

We discuss the properties of a phase space distribution function that can be expressed as a Gaussian convolution of the Wigner function corresponding to the oneelectron charge …
