French translation for "position operator"

opérateur de position

Example Sentences:

	1.	In quantum mechanics, the position operator is the operator that corresponds to the position observable of a particle. En physique quantique, l'opérateur de position ou opérateur de localisation est l'opérateur qui formalise l'observable position de l'état quantique d'une particule.
	2.	This is because the position operator is unbounded, and ψ {\displaystyle \psi } has to be chosen from its domain of definition. Ceci est dû au fait que l'opérateur de position est non borné, et il faut choisir ψ
	3.	In quantum theory, also operators with non-discrete spectrum are in use, such as the position operator Q {\displaystyle Q} in quantum mechanics. En théorie quantique, on utilise aussi des opérateurs dont le spectre n'est pas discret, comme l'opérateur de position Q
	4.	Newton–Wigner localization (named after Theodore Duddell Newton and Eugene Wigner) is a scheme for obtaining a position operator for massive relativistic quantum particles. L'opérateur de position de Newton-Wigner est un opérateur de position introduit par Théodore Dudell Newton et Eugene Wigner pour décrire la position de particules massives relativistes de spin arbitraire.
	5.	As an observable, consider the position operator Q {\displaystyle Q} , which acts on wavefunctions ψ {\displaystyle \psi } by ( Q ψ ) ( x ) = x ψ ( x ) {\displaystyle (Q\psi )(x)=x\psi (x)} . Considérons comme observable l'opérateur de position Q
	6.	Classically, the Fourier coefficients give the intensity of the emitted radiation, so in quantum mechanics the magnitude of the matrix elements of the position operator were the intensity of radiation in the bright-line spectrum. En physique classique, les coefficients de Fourier donnent l'intensité de la radiation émise, donc en mécanique quantique, les valeurs des éléments de matrice sont identifiés aux intensités des raies spectrales.
	7.	Making use of bra–ket notation, the state vector of the system at time t {\displaystyle \scriptstyle {t}} can be written | ψ ( t ) ⟩ = ∑ n c n A ( t ) e − i E n t / ℏ | ϕ n ⟩ {\displaystyle |\psi (t)\rangle =\sum _{n}c_{n}^{A}(t)e^{-iE_{n}t/\hbar }|\phi _{n}\rangle } , where the spatial wavefunction alluded to earlier is the projection of the state vector onto the eigenstates of the position operator ψ ( x , t ) = ⟨ x | ψ ( t ) ⟩ {\displaystyle \psi (x,t)=\langle x|\psi (t)\rangle } . En utilisant la notation bra-ket, le vecteur d'état du système au temps t
