  • Hard-core bosons in a zig-zag optical superlattice 
    Dhar, A.; Mishra, T.; Pai, R.V.; Mukerjee, S.; Das, B.P. (Physical Review A. 88(5); 2013; Article No. 053625 .)
    We study a system of hard-core bosons at half-filling in a one-dimensional optical superlattice. The bosons are allowed to hop to nearest- and next-nearest-neighbor sites. We obtain the ground-state phase diagram as a ...
  • Chiral Mott insulator with staggered loop currents in the fully frustrated Bose-Hubbard model 
    Dhar, A.; Mishra, T.; Maji, M.; Pai, R.V.; Mukerjee, S.; Paramekanti, A. (Physical Review B. 87(17); 2013; Article no. 174501.)
    Motivated by experiments on Josephson junction arrays in a magnetic field and ultracold interacting atoms in an optical lattice in the presence of a "synthetic" orbital magnetic field, we study the "fully frustrated" ...
  • Newton Lavrentiev regularization for ill-posed operator equations in Hilbert scalese 
    George, S.; Pareth, S.; Kunhanandan, M. (Applied Mathematics and Computation. 219(24); 2013; 11191-11197.)
    In this paper we consider the two step method for approximately solving the ill-posed operator equation F(x)=f, where F:D(F) subset of or equal to X to X, is a nonlinear monotone operator defined on a real Hilbert space ...
  • Comparative studies for multivariate model of human blood tissue using gaussian and lorentz oscillators and analysis using PLS regression 
    Parab, J.S.; Gad, R.S.; Naik, G.M.; Vetrekar, N. (International Journal of Electrical and Electronics Engineering Research (IJEEER). 3(2); 2013; 1-8.)
    The paper presents the modeling of the Multivariate model of the Human blood tissue using Gaussian and Lorentz Oscillators. The authors have demonstrated the spectroscopic modeling of the tissue in the region of near ...
  • Analysis of blood glucose using impedance technique 
    Nazareth, I.A.P.; Vernekar, S.R.; Gad, R.S.; Naik, G.M. (International Journal of Innovative Research in Electrical, Electronics, Instrumentation and Control Engineering (IJIREEICE). 1(9); 2013; 413-417.)
    This paper proposes a non invasive measurement technique to estimate the level of glucose by impedance measurement. This work presents a study of the varying concentrations of glucose using RF Impedance Spectroscopy (RIS). ...
  • Upconversion luminescence of cerium doped CoWO(4) nanomaterials 
    UmaSubramanian; Naik, S.J.; Tangsali, R.B.; Salker, A.V. (Journal of Luminescence. 134; 2013; 464-468.)
    In this paper we report the bluish green upconversion intrinsic photoluminescence (PL) observed at room temperature (RT) 300 K for the nanorange (27-50 nm) Ce3+ doped and undoped CoWO(4) powder samples sintered in air at ...
  • Hydration studies of Bentonite clay 
    Desai, R.R.; Desa, J.A.E.; Aswal, V.K. (AIP Conference Proceedings 1447; 2012; 197-198.)
    Bentonite clay when hydrated increases its volume several fold to form a pliable mass. X-ray diffraction showed that as hydration increases, the crystalline peaks due to kaolinite, calcite and quartz are gradually replaced ...
  • Three-body on-site interactions in ultracold bosonic atoms in optical lattices and superlattices 
    Singh, M.; Dhar, Arya; Mishra, T.; Pai, R.V.; Das, B.P. (Physical Review A. 85(5); 2012; Article ID: 051604(R).)
    The Mott-insulator-superfluid transition for ultracold bosonic atoms in an optical lattice has been extensively studied in the framework of the Bose-Hubbard model with two-body on-site interactions. We analyze the additional ...
  • Hydration of bentonite clay by X-ray and neutron scattering 
    Desa, J.A.E. (American Institute of Physics (AIP) Conf. Proc. , 1447. 2012; 197-198.)
    Bentonite clay when hydrated increases its volume several fold to form a pliable mass. X-ray diffraction showed that as hydration increases, the crystalline peaks due to kaolinite, calcite and quartz are gradually replaced ...
  • Characterization and magnetic properties of nanoparticle Ni(1-x)Zn(x)Fe(2)O(4) Ferrites prepared using Microwave assisted combustion method 
    Kothawale, M.M.; Tangsali, R.B.; Naik, G.K.; Budkuley, J.S. (Journal of Superconductivity and Novel Magnetism. 25(6); 2012; 1907-1911.)
    Nanoparticle Ni(1-x)Zn(x)Fe(2)O(4) (x = 0.35, 0.45) samples were prepared successfully via microwave assisted combustion method. Synthesis of nanosize materials at a low temperature using a domestic microwave oven is the ...
