Tunneling time and superposition principle [PDF]

open access: green, 2017
We show that scattering a quantum particle on a one-dimensional potential barrier as well as scattering the electromagnetic wave on a quasi-one-dimensional layered structure (both represent scattering problems with one 'source' and two 'sinks') violate the superposition principle; the role of nonlinear elements is played here by the potential barrier ...

Characterizing the superposition of arbitrary random quantum states and a known quantum state

open access: yesResults in Physics, 2023
The superposition of states is one of the most fundamental issues in the quantum world. Generally there do not exist physical operations to superpose two unknown random states with nonzero probability.

Quantum superposition principle and gravitational collapse: Scattering times for spherical shells [PDF]

open access: green, 2005
A quantum theory of spherically symmetric thin shells of null dust and their gravitational field is studied. In Nucl. Phys. 603 (2001) 515 (hep-th/0007005), it has been shown how superpositions of quantum states with different geometries can lead to a ...

Rheological equations of concrete state and relaxation of stress

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2022
Some approaches to the derivation of rheological equations of the mechanical state of concrete are considered and the principle of superposition of fraction deformations is justified in a nonlinear statement.

Quantum superposition principle and generation of short optical pulses [PDF]

open access: diamond, 2012
We discuss the propagation of laser radiation through a medium of quantum prepared {\Lambda}-type atoms in order to enhance the insight into the physics of QS-PT generator suggested in Phys. Rev. A 80, 035801 (2009).

Entangled Qubit States and Linear Entropy in the Probability Representation of Quantum Mechanics

open access: yesEntropy, 2022
The superposition states of two qubits including entangled Bell states are considered in the probability representation of quantum mechanics. The superposition principle formulated in terms of the nonlinear addition rule of the state density matrices is ...
