متن کاملDuality and Zero-Point Length of Spacetime
The action for a relativistic free particle of mass m receives a contribution 2mds from a path of infinitesimal length ds. Using this action in a path integral, one can obtain the Feynman propagator for a spinless particle of mass m. Assuming that the path integral amplitude is invariant under the “duality” transformation ds ! LPyds, one can calculate the modified Feynman propagator. I show tha...
متن کاملKaon Zero-Point Fluctuations in Neutron Star Matter
We investigate the contribution of zero-point motion, arising from uctuations in kaon modes, to the ground state properties of neutron star matter containing a Bose condensate of kaons. The zero-point energy is derived via the thermodynamic partition function, by integrating out uctuations for an arbitrary value of the condensate eld. It is shown that the vacuum counterterms of the chiral Lagra...
متن کاملNoninertial Zero-point Fluctuations: a Laboratory-oriented Introduction
Old results of Letaw on scalar vacuum radiation patterns that could be of interest for phonon analogies are used to emphasize the radio-metric nature of the Frenet-Serret invariants of the stationary worldlines, rather than sticking to the thermal interpretation of the vacuum excitations as apparent for the uniformly accelerated quantum detector (Unruh's interpretation). I focus next on the ele...
متن کاملEntanglement between a pair of spatially separated two - level atoms induced by zero point field fluctuations
PACS. 03.65.Ud – Entanglement and quantum nonlocality. Abstract. – We have considered the interaction of a pair of spatially separated two-level atoms with the electromagnetic field in its vacuum state and we have analyzed the amount of entanglement induced between the two atoms by the non local field fluctuations. This has allowed us to characterize the quantum nature of the non local correlat...
