Local PT symmetry violates the no-signaling principle.
Bender et al. [Phys. Rev. Lett. 80, 5243 (1998)] have developed PT-symmetric quantum theory as an extension of quantum theory to non-Hermitian Hamiltonians. We show that when this model has a local PT symmetry acting on composite systems, it violates the nonsignaling principle of relativity. Since the case of global PT symmetry is known to reduce to standard quantum mechanics A. Mostafazadeh [J...

Received: January 18, 2005 Revised: July 3, 2007 Communicated by Ulf Rehmann Abstract. We deal with a ertain observation mapping de ned by means of weighted measurments on a dynami al system and give ne essary and su ient onditions, under whi h this mapping is generially an inje tive immersion. 2000 Mathemati s Subje t Classi ation: 93B07, 37C20, 37C10, 94A20.
متن کامل(An Analysis of Principle no.8 of the Constitution)
This article has analyzed principle no.8 of the Constitution from three aspects: 1-verbal analysis 2-conceptual analysis 3-ways to execute this principle. In first section a precise definition of "call to good", "good and evil" (both in law and in jurisprudence) and "government" have been presented. In second section to have a better understanding of principle no.8, issues such as the relation ...
متن کاملLocal Observability of Rolling
This paper investigates local observability of the pose and motion of a curved threedimensional object rolling on a rough horizontal plane. The plane models a controllable robotic palm imbued with tactile sensors. The palm can accelerate in arbitrary translational directions and the tactile sensors can determine the contact location between the palm and the rolling object at every instant in ti...
متن کاملThe Observability of Independence under Monetary-based Elicitation
Graphical models 1] have proved invaluable as a language for encoding probability distributions , due primarily to their facility in expressing independencies among variables. Suucient independencies yield not only parsimonious models, but insights into the underlying system being represented; conversely, the lack of any independence structure renders a graphical description, per se, essentiall...
