In this paper we discuss the information system requirements of an e-Science scenario, drawn from chemistry research, and describe our approach to a solution which employs notions of adaptive (and adaptable) hypermedia and utilises Semantic Web technologies.

Conventional paper-based scientific publications are limited in the amount of data and interaction they can provide. Simply placing an electronic copy of such a publication on the web makes for easier distribution, but more can be achieved by making use of the technology to navigate through the paper, to show the links between calculated parameters and the… (More)

Using the eigenvalue definition of binomial states we construct new intermediate number-coherent states which reduce to number and coherent states in two different limits. We reveal the connection of these intermediate states with photonadded coherent states and investigate their non-classical properties and quasiprobability distributions in detail. It is… (More)

A necessary and sufficient condition for the maximal entanglement of bipartite nonorthogonal pure states is found. The condition is applied to the maximal entanglement of coherent states. Some new classes of maximally entangled coherent states are explicited constructed; their limits give rise to maximally entangled Belllike states.

Over the past few years much effort has been put into studying the entanglement of multipartite systems both qualitatively and quantitatively. Entangled states constitute a valuable resource in quantum information processing [1]. Quite recently, entanglement in quantum operations [2–4] and entanglement in indistinguishable fermionic and bosonic systems… (More)

We investigate the use of semantic technologies to describe chemical data in a manner that facilitates the subsequent reuse of both the data and the analysis procedure used to produce the data. We first propose an approach to describe and record the analysis process for a physical chemistry laser spectroscopic experiment that serves as an e-logbook for… (More)

Using the concepts of publication@source technology, the data obtained from a range of spectroscopy and surface tension experiments, and that obtained from a number of related large computational simulations, have been stored in such a way as to enable a viewer to trace back through the analysis methods to the raw data. The storage of the simulation data is… (More)

We investigate the dynamics of a four-photon Jaynes-Cummings model for large photon number. It is shown that at certain times the cavity field is in a pure state which is a superposition of two Kerr states, analogous to the Schrödinger cat state (superposition of two coherent states) which occurs in the one and two photon cases.

Intermediate states interpolating coherent states and Pegg-Barnett phase states are investigated using the ladder operator approach. These states reduce to coherent and Pegg-Barnett phase states in two different limits. Statistical and squeezing properties are studied in detail.

We study su(2) and su(1,1) displaced number states. Those states are eigenstates of density-dependent interaction systems of quantized radiation field with classical current. Those states are intermediate states interpolating between number and displaced number states. Their photon number distribution, statistical and squeezing properties are studied in… (More)
