Introduction: Surface Histories.
The first section of this issue brings together four essays on “surfaces” – a subject matter which might seem conspicuous or, indeed, palpable enough. Just think of the sheets of paper, window panes, and haptic interfaces surrounding you: the world, evidently, is diffused with surfaces, membranes, and boundaries of all sorts. Some of these things have been salient, for obvious reasons in fields...
متن کاملBohmian Histories and Decoherent Histories
The predictions of the Bohmian and the decoherent (or consistent) histories formulations of the quantum mechanics of a closed system are compared for histories — sequences of alternatives at a series of times. For certain kinds of histories, Bohmian mechanics and decoherent histories may both be formulated in the same mathematical framework within which they can be compared. In that framework, ...
متن کاملConsistency of Quantum Histories
We prove that for an open system, in the Markovian regime, it is always possible to construct an infinite number of non trivial sets of histories that exactly satisfy the probability sum rules. In spite of being perfectly consistent, these sets manifest a very non–classical behavior: they are quite unstable under the addition of an extra instant to the list of times defining the history. To eli...
متن کاملQuerying Shapes of Histories
We present a shape de nition language, called SDL, for retrieving objects based on shapes contained in the histories associated with these objects. It is a small, yet powerful, language that allows a rich variety of queries about the shapes found in historical time sequences. An interesting feature of SDL is its ability to perform blurry matching. A \blurry" match is one where the user cares ab...
متن کاملProperties of consistent histories.
We describe some properties of consistent sets of histories in the Gell-Mann–Hartle formalism, and give an example to illustrate that one cannot recover the standard predictions, retrodictions and inferences of quasiclassical physics using the criterion of consistency alone. PACS numbers: 03.65.Bz
