Abstract: Considering that three two-level atoms are initially in the GHZ single state and two of the atoms are simultaneously put into a cavity initially in the coherent state, we investigate the dipole squeezing properties of the two atoms inside the cavity under the condition of resonant interaction. It is shown that dipole squeezing properties of the two atoms inside the cavity are strongly affected by rotation manipulating of the atom outside the cavity.

Abstract: Considering three two-level atoms initially in the W state, then two of them are placed into two initially empty cavities respectively and made resonantly interacted. The two-atom entanglement evolution inside cavities is investigated. The effects of rotational manipulation and state-selective measurement of the atoms outside the cavities on the two-atom entanglement evolution inside cavities are discussed. The results obtained using the numerical method show that the two-atom entanglement inside cavities is controlled by manipulating the atom outside the cavity.
Generation of Entanglement Outside of the Light Cone  [PDF]
J. D. Franson
Physics , 2007, DOI: 10.1080/09500340801983129
Abstract: The Feynman propagator has nonzero values outside of the forward light cone. That does not allow messages to be transmitted faster than the speed of light, but it is shown here that it does allow entanglement and mutual information to be generated at space-like separated points. These effects can be interpreted as being due to the propagation of virtual photons outside of the light cone or as a transfer of pre-existing entanglement from the quantum vacuum. The differences between these two interpretations are discussed.
Bound-state eigenenergy outside and inside the continuum for unstable multilevel systems  [PDF]
Manabu Miyamoto
Physics , 2005, DOI: 10.1103/PhysRevA.72.063405
Abstract: The eigenvalue problem for the dressed bound-state of unstable multilevel systems is examined both outside and inside the continuum, based on the N-level Friedrichs model which describes the couplings between the discrete levels and the continuous spectrum. It is shown that a bound-state eigenenergy always exists below each of the discrete levels that lie outside the continuum. Furthermore, by strengthening the couplings gradually, the eigenenergy corresponding to each of the discrete levels inside the continuum finally emerges. On the other hand, the absence of the eigenenergy inside the continuum is proved in weak but finite coupling regimes, provided that each of the form factors that determine the transition between some definite level and the continuum does not vanish at that energy level. An application to the spontaneous emission process for the hydrogen atom interacting with the electromagnetic field is demonstrated.
Looking from the inside and from the outside  [PDF]
Alessandra Carbone,S. Semmes
Mathematics , 1996,
Abstract: One often sees a sharp distinction in mathematics between descriptions from the outside and from the inside. Think of defining a set in the plane through an algebraic equation, or dynamically as the closure of the orbit of some point under iterations of a given mapping. In logic one sees this dichotomy in the descriptions of sets of tautologies through semantics and proofs. Logic provides several tools for making outer descriptions of mathematical objects. This paper concerns a slightly complicated mixture of themes related to inner descriptions and formal proofs. We use the notion of feasibility to embed mathematical structures into spaces of logical formulas, from which we can obtain new structures through proofs. We present new geometries on finitely generated groups through proofs, and new structure on the rational numbers (or other fields) which is susceptible to dynamical processes, such as the action of $SL(2,Z)$ by projective transformations. We consider the topological notion of {\em Serre fibrations}. This entails more difficulties of formalization, but basic points arise already for {\em torus bundles}, which present exponential distortion through cycling in a nicely geometric way. One of our goals is to bring out mathematical structure related to cuts and cut elimination. Our geometry on groups through proofs is far from the word metric precisely because of the cut rule. We want to explore the idea that in general the existence of short proofs with cuts should be related to internal symmetry or dynamical processes in the underlying mathematical objects. We also want to bring ordinary mathematical proofs closer to proof theory. In this regard the topological example is attractive for presenting realistic difficulties.
Influence of selective atomic measurement on the entanglement properties of a two-atom outside cavity

Lu Dao-Ming,

中国物理 B , 2011,
Abstract: Considering three two-level atoms initially in the W or Greenberger--Horne--Zeilinger (GHZ) state, one of the three atoms is put into an initially coherent light cavity and made to resonantly interact with the cavity. The two-atom entanglement evolution outside the cavity is investigated. The influences of state-selective measurement of the atom inside the cavity and strength of the light field on the two-atom entanglement evolution outside the cavity are discussed. The results obtained from the numerical method show that the two-atom entanglement outside the cavity is strengthened through state-selective measurement of the atom inside the cavity. In addition, the strength of the light field also influences the two-atom entanglement properties.

Abstract: The dissipation of chlorpyrifos on pakchoi inside and outside greenhouse was studied. The decline curve of chlorpyrifos on pakchoi could be described as first-order kinetic. The experimental data showed that both the hermetic environment of greenhouse and season affected dissipation rates of chlorpyrifos on pakchoi. Chlorpyrifos declined faster outside greenhouse than inside greenhouse. Chlorpyrifos residues at pre-harvest time were below the maximum residue limits(MRLs) fixed in China, whereas the values inside greenhouse were higher than those outside greenhouse by almost 50%. The recommended pre-harvest time established under conditions of open field might not always fit to greenhouse production.
Inside-Outside Estimation Meets Dynamic EM  [PDF]
Detlef Prescher
Computer Science , 2004,
Abstract: We briefly review the inside-outside and EM algorithm for probabilistic context-free grammars. As a result, we formally prove that inside-outside estimation is a dynamic-programming variant of EM. This is interesting in its own right, but even more when considered in a theoretical context since the well-known convergence behavior of inside-outside estimation has been confirmed by many experiments but apparently has never been formally proved. However, being a version of EM, inside-outside estimation also inherits the good convergence behavior of EM. Therefore, the as yet imperfect line of argumentation can be transformed into a coherent proof.
Slavic prefixes inside and outside VP  [cached]

Abstract: Most Slavic prefixes can be assigned to one of two large cate- gories, lexical and superlexical. The lexical prefixes are like Germanic particles, in having resultative meanings, often spatial, but often id- iosyncratic. The superlexical prefixes are like adverbs or auxiliary verbs, having aspectual and quantificational meanings. I present a syntactic account of the two types of prefix, arguing that the lexical ones are to be analyzed essentially like the Germanic particles, and that their VP-internal position accounts for many of their properties, while the superlexical ones originate outside VP.
Electric fields inside and outside an anisotropic dielectric sphere

Li Ying-Le,Wang Ming-Jun,

中国物理 B , 2009,
Abstract: Analytical expressions of electric fields inside and outside an anisotropic dielectric sphere are presented by transforming an anisotropic medium into an isotropic one based on the multi-scale transformation of electromagnetic theory. The theoretical expressions are consistent with those in the literature. The inside electric field, the outside electric field and the angle between their directions are derived in detail. Numerical simulations show that the direction of the outside field influences the magnitude of the inside field, while the dielectric constant tensor greatly affects its direction.
