Space of State Vectors in PT Symmetrical Quantum Mechanics [PDF]
Space of states of PT symmetrical quantum mechanics is examined. Requirement that eigenstates with different eigenvalues must be orthogonal leads to the conclusion that eigenfunctions belong to the space with an indefinite metric.

Quantum phase estimations with spin coherent states superposition [PDF]
The quantum metrological performance of spin coherent states superposition is considered, and conditions for measurements with the Heisenberg-limit (HL) precision are identified. It is demonstrated that the choice of the parameter-generating operator can

Boundedness and continuity of superposition operator on Er(p) and Fr(p) [PDF]
Let X ∈ {Er(p)V , Fr(p)}, in this research, necessary and sufficient conditions are given for superposition operator to act from X into the space l1. Moreover, necessary and sufficient conditions are obtained for superposition operator acting from X into

Analytic Morrey Spaces and Bloch-Type Spaces
This paper is devoted to characterizing the boundedness of the Riemann-Stieltjes operators from analytic Morrey spaces to Bloch-type spaces. Moreover, the boundedness of the superposition operator and weighted composition operator on analytic Morrey ...

Formation of required distributions on the basis of decomposition by vortex eigen functions of a bounded non-paraxial propagation operator [PDF]
The solution of the problem of overcoming the diffraction limit based on the representation of an optical signal in the form of a superposition of communication modes matched with the vortex eigenfunctions of a bounded (in the object and spectral regions)

Macroscopicity of quantum superpositions on a one-parameter unitary path in Hilbert space [PDF]
We analyze quantum states formed as superpositions of an initial pure product state and its image under local unitary evolution, using two measurement-based measures of superposition size: one based on the optimal quantum binary distinguishability of the

Spectral of the nonlinear weighted superposition operator on Fock spaces
We follow several approaches in nonlinear spectral theory and determine the various spectral forms for the nonlinear weighted superposition operator on Fock spaces. The results show that most of the forms introduced so far coincide and contain singeltons.

Experiments testing macroscopic quantum superpositions must be slow [PDF]
We consider a thought experiment where the preparation of a macroscopically massive or charged particle in a quantum superposition and the associated dynamics of a distant test particle apparently allow for superluminal communication.
