Making a wavefunctional representation of physical states congruent with the false vacuum hypothesis of Sidney Coleman
A. W. Beckwith
We examine quantum decay of the false vacuum in the driven sine-Gordon system and show how both together permit construction of a Gaussian wave functional. This is due to changing…
Semiclassical Methods in Curved Spacetime and Black Hole Thermodynamics
Horacio E. Camblong, Carlos R. Ordonez
Improved semiclassical techniques are developed and applied to a treatment of a real scalar field in a -dimensional gravitational background. This analysis, leading to a derivat…
Avalanche-driven fractal flux distributions in NbN superconducting films
I. A. Rudnev, D. V. Shantsev, T. H. Johansen +1
Flux distributions in thin superconducting NbN films placed in a perpendicular magnetic field have been studied using magneto-optical imaging. Below 5.5 K the flux penetrates in th…
Duality and Operator Algebras II: Operator Algebras as Banach Algebras
David P. Blecher, Bojan Magajna
We answer, by counterexample, several open questions concerning algebras of operators on a Hilbert space. The answers add further weight to the thesis that, for many purposes, such…
Frames, Graphs and Erasures
Bernhard G. Bodmann, Vern I. Paulsen
Two-uniform frames and their use for the coding of vectors are the main subject of this paper. These frames are known to be optimal for handling up to two erasures, in the sense th…
Finger patterns produced by thermomagnetic instability in superconductors
A. L. Rakhmanov, D. V. Shantsev, Y. M. Galperin +1
A linear analysis of thermal diffusion and Maxwell equations is applied to study the thermomagnetic instability in a type-II superconducting slab. It is shown that the instability…
