Aksum University (AKU) faculties’ needs for support in training and academic research: a basis for improvement in productivity of publication

The objective of this study is to identify and describe Aksum University (AKU) faculties’ training and support needs for academic research as a basis of improvement in the productivity of academic research publications. The stratified random sample was 51 faculties from five of the six colleges in Aksum University representing 16.3% of the oncampus teaching faculties. The hypotheses of the study were: (a) training in data analysis and research writing is needed; (b) faculties know how to do research design and methodology; (c) faculties need internet access; (d) research training does not impact teaching; and (e) there are no qualified faculties at AKU for research training. Two Principle Component Analysis factors related to these hypotheses were described as a training factor TFAC1(I need training in data analysis and research report writing ) and a support factor TFAC2 (Internet access is essential and research class would not interfere with teaching).Keywords: Training, Support, Research, Publications, Universit

Abelian Sandpile Model on the Husimi Lattice of Square Plaquettes

An Abelian sandpile model is considered on the Husimi lattice of square plaquettes. Exact expressions for the distribution of height probabilities in the Self-Organized Critical state are derived. The two-point correlation function for the sites deep inside the Husimi lattice is calculated exactly.Comment: 12 pages, LaTeX, source files and some additional information available at http://thsun1.jinr.dubna.su/~shcher

Preparing encoded states in an oscillator

Recently a scheme has been proposed for constructing quantum error-correcting codes that embed a finite-dimensional code space in the infinite-dimensional Hilbert space of a system described by continuous quantum variables. One of the difficult steps in this scheme is the preparation of the encoded states. We show how these states can be generated by coupling a continuous quantum variable to a single qubit. An ion trap quantum computer provides a natural setting for a continuous system coupled to a qubit. We discuss how encoded states may be generated in an ion trap.Comment: 5 pages, 4 figures, RevTe

Creation of macroscopic superposition states from arrays of Bose-Einstein condensates

We consider how macroscopic quantum superpositions may be created from arrays of Bose-Einstein condensates. We study a system of three condensates in Fock states, all with the same number of atoms and show that this has the form of a highly entangled superposition of different quasi-momenta. We then show how, by partially releasing these condensates and detecting an interference pattern where they overlap, it is possible to create a macroscopic superposition of different relative phases for the remaining portions of the condensates. We discuss methods for confirming these superpositions.Comment: 7 pages, 5 figure

Sympathetic Cooling of Trapped Cd+ Isotopes

We sympathetically cool a trapped 112Cd+ ion by directly Doppler-cooling a 114Cd+ ion in the same trap. This is the first demonstration of optically addressing a single trapped ion being sympathetically cooled by a different species ion. Notably, the experiment uses a single laser source, and does not require strong focusing. This paves the way toward reducing decoherence in an ion trap quantum computer based on Cd+ isotopes.Comment: 4 figure
