Research of X-ray induced conductivity of ZnSe sensors for their application in isotopic thickness gaugesJun 11 2011Measurements of intrinsic conductivity and X-ray induced conductivity were performed on specially undopped ZnSe samples. The measurements demonstrated that sensors made of ZnSe have minor intrinsic conductivity when heating up to the temperature of 180 ... More
Covariant local field theory equations following from the relativistic canonical quantum mechanics of arbitrary spinAug 22 2014Sep 19 2014The new relativistic equations of motion for the particles with spin s=1, s=3/2, s=2 and nonzero mass have been introduced. The description of the relativistic canonical quantum mechanics of the arbitrary mass and spin has been given. The link between ... More
Quantum Lie algebras of type A_nOct 03 1995Dec 07 1995It is shown that the quantised enveloping algebra of sl(n) contains a quantum Lie algebra, defined by means of axioms similar to Woronowicz's., This gives rise to Lie algebra-like generators and relations for the locally finite part of the quantised enveloping ...

Kinetics of Charge Transport in Wide-Band Semiconductors at the Detection of X-Ray RadiationJan 28 2011As a result of absorption of X-ray quantum in a semiconductor, the generation of electron-hole pairs takes place in a small volume (diameter < 0.5 mkm). Their surplus energy is lost due to the scattering on phonons of the crystal lattice. Spatial distribution ... More
Likelihood-free MCMC with Approximate Likelihood RatiosMar 10 2019We propose a novel approach for posterior sampling with intractable likelihoods. This is an increasingly important problem in scientific applications where models are implemented as sophisticated computer simulations. As a result, tractable densities ... More
Simulating Data Access Profiles of Computational Jobs in Data GridsFeb 26 2019The data access patterns of applications running in computing grids are changing due to the recent proliferation of high speed local and wide area networks. The data-intensive jobs are no longer strictly required to run at the computing sites, where the ... More

Paramagnetic Meissner effect in ZrB12 single crystal with non-monotonic vortex-vortex interactionsAug 02 2017The magnetic response related to paramagnetic Meissner effect (PME) is studied in a high quality single crystal ZrB12 with non-monotonic vortex-vortex interactions. We observe the expulsion and penetration of magnetic flux in the form of vortex clusters ... More
Specific features of the luminescence and conductivity of zinc selenide on exposure to X-ray and optical excitationJan 29 2011The set of experimental data on the X-ray-excited luminescence and X-ray induced conductivity of ZnSe are compared to the data on the photoluminescence and photoconductivity. It is experimentally established that the current-voltage characteristics and ... More
Potential of a next generation neutrinoless double beta decay experiment based on ZnMoO4 scintillating bolometersDec 15 2011The search for neutrinoless double beta decay probes lepton number conservation with high sensitivity and investigates the neutrino nature and mass scale. Experiments presently in preparation will cover the quasi-degeneracy region of the neutrino mass ... More
Performance of ZnMoO4 crystal as cryogenic scintillating bolometer to search for double beta decay of molybdenumOct 01 2010Zinc molybdate (ZnMoO4) single crystals were grown for the first time by the Czochralski method and their luminescence was measured under X ray excitation in the temperature range 85-400 K. Properties of ZnMoO4 crystal as cryogenic low temperature scintillator ... More
Growth and characterization of a Li2Mg2(MoO4)3 scintillating bolometerFeb 06 2018Lithium magnesium molybdate (Li$_2$Mg$_2$(MoO$_4$)$_3$) crystals were grown by the low-thermal-gradient Czochralski method. Luminescence properties of the material (emission spectra, thermally stimulated luminescence, dependence of intensity on temperature, ... More
Aboveground test of an advanced Li$_2$MoO$_4$ scintillating bolometer to search for neutrinoless double beta decay of $^{100}$MoOct 25 2014Dec 17 2014Large lithium molybdate (Li$_2$MoO$_4$) crystal boules were produced by using the low thermal gradient Czochralski growth technique from deeply purified molybdenum. A small sample from one of the boules was preliminary characterized in terms of X-ray-induced ... More
CdWO4 crystal scintillators from enriched isotopes for double beta decay experimentsFeb 20 2013Cadmium tungstate crystal scintillators enriched in 106Cd and 116Cd were developed. The produced scintillators exhibit good optical and scintillation properties, and a low level of radioactive contamination. Experiments to search for double beta decay ... More
Purification of molybdenum oxide, growth and characterization of medium size zinc molybdate crystals for the LUMINEU programDec 12 2013The LUMINEU program aims at performing a pilot experiment on neutrinoless double beta decay of 100Mo using radiopure ZnMoO4 crystals operated as scintillating bolometers. Growth of high quality radiopure crystals is a complex task, since there are no ... More
