The superposition operator in the space of functions continuous and converging at infinity on the real half-axis

open access: yesAdvances in Nonlinear Analysis, 2019
We will consider the so-called superposition operator in the space CC(ℝ+) of real functions defined, continuous on the real half-axis ℝ+ and converging to finite limits at infinity.

Quantum conformal symmetries for spacetimes in superposition [PDF]

open access: yesQuantum
Without a complete theory of quantum gravity, the question of how quantum fields and quantum particles behave in a superposition of spacetimes seems beyond the reach of theoretical and experimental investigations.

Continuity of the Superposition Operator On Orlicz-Sobolev Spaces [PDF]

open access: yes, 1994
We give sufficient conditions for a homogeneous superposition operator to be a continuous mapping between Orlicz-Sobolev spaces.

Experimental implementation of arbitrary entangled operations

open access: yesNew Journal of Physics, 2020
Quantum entanglement lies at the heart of quantum mechanics in both fundamental and practical aspects. The entanglement of quantum states has been studied widely both theoretically and experimentally, however, the entanglement of operators has not been ...

The nonlinear superposition operator on harmonic fock spaces [PDF]

open access: yes
We describe the conditions under which the superposition operator maps one harmonic Fock space into another. We further proved that all superposition operators on the spaces are both bounded and globally Lipschitz continuous.

Free vibration analysis of plates and shells by using the Superposition Method [PDF]

open access: yes, 2010

The measurement problem in quantum mechanics

open access: yesScience & Philosophy, 2019
In this paper, we discuss the importance of measurement in quantum mechanics and the so-called measurement problem. Any quantum system can be described as a linear combination of eigenstates of an operator representing a physical quantity; this means ...

Monotonicity properties of the superposition operator and their applications [PDF]

open access: yes, 2008
We establish some properties of the superposition operator which are associated with monotonicity. Those properties are expressed in terms of the notion of degree of decrease or degree of increase.

Uniform continuity and Brézis–Lieb-type splitting for superposition operators in Sobolev space

open access: yesAdvances in Nonlinear Analysis, 2018
Using concentration-compactness arguments, we prove a variant of the Brézis–Lieb-Lemma under weaker assumptions on the nonlinearity than known before.

Effect of Classical and Quantum Superposition of Atomic States on Quantum Correlations

open access: yesAdvances in Mathematical Physics, 2023
In this paper, we report the effect of classical and quantum superposition of atomic states on quantum correlations. Coupled photon pairs generated in a ladder quantum beat laser using coherent-induced classical field and atomic state coherent ...
