    We present optical storage experiments with weak coherent states and heralded single photons by using the atomic frequency comb technique in the long-lived hyperfine levels in an ensemble of Pr3+ ions doped into a solid.</p

    Technology developments for ACIGA high power test facility for advanced interferometry

    No full text
    Copyright © Institute of Physics and IOP Publishing Limited 2005.The High Optical Power Test Facility for Advanced Interferometry has been built by the Australian Consortium for Interferometric Gravitational Astronomy north of Perth in Western Australia. An 80 m suspended cavity has been prepared in collaboration with LIGO, where a set of experiments to test suspension control and thermal compensation will soon take place. Future experiments will investigate radiation pressure instabilities and optical spring effects in a high power optical cavity with ~200 kW circulating power. The facility combines research and development undertaken by all consortium members, whose latest results are presented.P Barriga, M Barton, D G Blair, A Brooks, R Burman, R Burston, E J Chin, J Chow, D Coward, B Cusack, G de Vine, J Degallaix, J C Dumas, M Feat, S Gras, M Gray, M Hamilton, D Hosken, E Howell, J S Jacob, L Ju, T L Kelly, B H Lee, C Y Lee, K T Lee, A Lun, D E McClelland, K McKenzie, C Mow-Lowry, A Moylan, D Mudge, J Munch, D Rabeling, D Reitze, A Romann, S Schediwy, S M Scott, A Searle, B S Sheard, B J J Slagmolen, P Veitch, J Winterflood, A Woolley, Z Yan and C Zha

    Economic Transformation Database of Transition Economies

    No full text
    The Economic Transformation Database of Transition Economies [ETD-TE] provides a balanced panel of internationally comparable sectoral data on output and employment in fourteen former-Soviet Republics. The ETD-TE is designed to easily combine with the GGDC/UN-WIDER Economic Transformation Database [ETD]. It enables a comparative analysis of growth and structural transformation between the former-Soviet Union countries, and other advanced and developing countries. More information about this data set can be found on the associated page on the website of the Groningen Growth and Development Centre. When using these data (for whatever purpose), please make the following reference: Hamilton, C. and G. J. de Vries (2025). The Structural Transformation of Transition Economies. World Development, 191, Article 106977. User information The ETD-TE includes the following data: Countries Armenia Azerbaijan Belarus Estonia Georgia Kazakhstan Kyrgyzstan Latvia Lithuania Moldova Russian Federation Tajikistan Ukraine Uzbekistan Variables Persons Employed (thousands) Constant price value added in local currency (millions) Nominal price value added in local currency (millions) *Where countries changed or revalued currency during the sample period, all VA data is provided in units of the most recent/current currency.
