In this paper we explore how to describe a bulk moving particle in the dual conformal field theories (CFTs). One aspect of this problem is to construct the dual state of the moving particle. On the other hand one should find the corresponding operators ...

We present formal 1D calculations of the time derivatives of the mean values of the position () and momentum (p) operators in the coordinate representation... B Bressler - 《Psychoanalytic Review the》 被引量: 16发表: 1956年 Thinking with Irigaray In lieu of an abstract, here is a brief ...
The Hartman effect is analyzed in both the position and momentum representations of the problem. The importance of Wigner tunneling and deep tunneling is singled out. It is shown quantitatively how the barrier acts as a filter for low momenta (quantum speed up) as the width increases, and a ...

And you need to distinguish between the integration for Pμ and the integration for ϕ(x). So use k for the first integral and k′ for the second. You need the commutation relation on the operators a†,a,b†,b. There are different conventions, so you have to look up which...
(ii) The physical interpretation of these quantities is difficult, and may not improve understanding of the process. (iii) Direct experimental evidence of the entanglement is often practically impossible, requiring the measurement of incompatible observables, such as momentum and position. One solution...
It is shown that the assumption of the existence of putative values for position and momentum observables for one single particle is incompatible with quantum mechanics. 关键词: Bell–Kochen–Specker hidden variables contextuality position and momentum DOI: 10.1007/s10701-007-9148-2 被引量: 2 ...
Two-Parameter Deformation of the Oscillator Algebra and ( p, q )–Analog of Two-Dimensional Conformal Field Theory The two-parameter deformation of canonical commutation relations is discussed. The self-adjointness property of the (p, q)-deformed position Q and momentum P operators is investigated...
