Ubiquity of quantum zero-point fluctuations in dislocation glide

Shuffle-glide dislocation transformation in Si

The transformation of dislocation cores from the shuffle to the glide set of {111} glide planes in Si is examined in this work. The transformation is thermally activated and is favored by a resolved shear stress which applies no force on the original perfect shuffle dislocation. A resolved shear stress driving dislocation motion in the glide plane is not observed to promote the transition. The ...

Conjectured Breaking of the Superluminal Quantum Correlations By Türbulent Fluctuations of the Zero Point Vacuum Field

If the observed superluminal quantum correlations are disturbed by turbulent fluctuations of the zero point vacuum energy field, with the turbulent energy spectrum assumed to obey the universal Kolmogoroff law, a length is derived above which the correlations are conjectured to break. A directional dependence of this length would establish a preferred reference system at rest with the zero poin...

Quantum Vacuum Fluctuations, Zero Point Energy and the Question of Observable Noise

Kaon 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...
