    Open access publishing: What is world’s best practice?

    Open access publishing delivers on the dream of centuries - the free and unfettered access to the written word. However there are shades of openness and the question raised is 'what is world's best practice for open access publishing?' Four criteria are proposed to generate a star rating for an open access journal - for ‘openness’ - with a star available for meeting each criterion, to a maximum of four. The open access criteria for scoring star ratings are: (1) There is no barrier to access for the reader; (2) It is free to the author/s; (3) Copyright is retained by the author/s; and (4) The paper can be freely distributed under licence. The Journal of Organic Systems 'ticks all the boxes' to rate as a four-star open access journal

    Nonequilibrium Quantum Evolution of Open Systems

    Get PDF
    We apply the Liouville-von Neumann (LvN) approach to open systems to describe the nonequilibrium quantum evolution. The Liouville-von Neumann approach is a unified method that can be applied to both time-independent (closed) and time-dependent (open) systems and to both equilibrium and nonequilibrium systems. We study the nonequilibrium quantum evolution of oscillator models for open boson and fermion systemsComment: RevTex 13 pages, Contributed to the journal "Condensed Matter Physics

    Adiabatic Approximation for weakly open systems

    Full text link
    We generalize the adiabatic approximation to the case of open quantum systems, in the joint limit of slow change and weak open system disturbances. We show that the approximation is ``physically reasonable'' as under wide conditions it leads to a completely positive evolution, if the original master equation can be written on a time-dependent Lindblad form. We demonstrate the approximation for a non-Abelian holonomic implementation of the Hadamard gate, disturbed by a decoherence process. We compare the resulting approximate evolution with numerical simulations of the exact equation.Comment: New material added, references added and updated, journal reference adde

    Open source repositories: Implications for libraries

    Get PDF
    Software that is accepted as “Open source” should comply with 10 conditions which are itinerated in the paper. The paper subsequently describes the application of open source initiatives in the digital library context. Three open source digital library initiatives developed by the Digital Library Research Group at the Faculty of Computer Science and information Technology, University of Malaya are highlighted. These are; (a) MyManuskrip: digital library of Malay manuscripts; (b) MyAIS : Digital library of Malaysian scholarly journals and conference proceedings; and (d) DSpace@Um: a digital library of dissertations, theses and final year project reports. Other “free” systems such as EJUM: electronic journal of university of Malaya is also described to highlight the slight difference between open source and being free. The paper also describes the libraries involved in the initiatives and the changing eco-system which libraries must accept to embrace the open source culture

    A simple model of quantum trajectories

    Get PDF
    Quantum trajectory theory, developed largely in the quantum optics community to describe open quantum systems subjected to continuous monitoring, has applications in many areas of quantum physics. In this paper I present a simple model, using two-level quantum systems (q-bits), to illustrate the essential physics of quantum trajectories and how different monitoring schemes correspond to different ``unravelings'' of a mixed state master equation. I also comment briefly on the relationship of the theory to the Consistent Histories formalism and to spontaneous collapse models.Comment: 42 pages RevTeX including four figures in encapsulated postscript.
