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 ...

The Heisenberg algebra (2.2) can be represented continuously on momentum space wave functions ψ(p) =< p|ψ > as pˆψ(p) = pψ(p) xˆψ(p) = i (1 + βp2) ∂ ψ(p) ∂p (2.5) The position and momentum operators are symmetric on the domain S∞ with respect to the ...
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 ...

The ordering problem does not occur because of the absence of product between the mass and momentum operators, the last case is then more straightforward and gives us an analytical expression for the mass distribution m(r,θ)m(r,θ), the plot of this solution is shown in Fig. 4. In ...

A relativistic spin operator is the difference between the total and the orbital angular momentum. As the unique position operator for a localized state, the remarkable Newton-Wigner position operator, which has all the desirable commutation relations of a position operator, can give a proper spin ...
