  • Nano-porous structure of a porous ceramics from rice husk 
    Raut-Dessai, R.; Desa, J.A.E.; Sen, D.; Mazumder, S. (Transactions of The Indian Ceramic Society. 71(4); 2012; 243-246.)
    A porous ceramics is obtained using rice husk as the source of silica. The modification of mesoscopic structure under different sintering conditions has been investigated using neutron scattering techniques and scanning ...
  • The inhomogeneous extended Bose-Hubbard model: A mean-field theory 
    Kurdestany, J.M.; Pai, R.V.; Pandit, Rahul (Annalen Der Physik. 524(41702); 2012; 234-244.)
    We develop an inhomogeneous mean-field theory for the extended Bose-Hubbard model with a quadratic, confining potential. In the absence of this potential, our mean-field theory yields the phase diagram of the homogeneous ...
  • Bose-Hubbard model in a strong effective magnetic field: Emergence of a chiral Mott insulator ground state 
    Dhar, A.; Maji, M.; Mishra, T.; Pai, R.V.; Mukerjee, S.; Paramekanti, A. (Physical Review A. 85(4); 2012; Article ID: 041602(R).)
    Motivated by experiments on Josephson junction arrays, and cold atoms in an optical lattice in a synthetic magnetic field, we study the "fully frustrated" Bose-Hubbard model with half a magnetic flux quantum per plaquette. ...
  • Bose-Hubbard models in confining potentials: Inhomogeneous mean-field theory 
    Pai, R.V.; Kurdestany, J.M.; Sheshadri, K.; Pandit, Rahul (Physical Review B. 85(21); 2012; Article ID: 214524.)
    An extensive study of Mott insulator (MI) and superfluid (SF) shells in Bose-Hubbard (BH) models for bosons in optical lattices with harmonic traps is presented. For this we apply the inhomogeneous mean-field theory ...
  • Ground-state properties of linear-exchange quantum spin models 
    Danu, B.; BrijeshKumar; Pai, R.V. (EPL - Europhysics Letters. 100(2); 2012; Article ID: 27003.)
    We study a class of one-dimensional antiferromagnetic quantum spin-1/2 models using DMRG. The exchange interaction in these models decreases linearly with the separation between the spins, J(ij) = R - vertical bar i-j ...
  • Role of crystal defects in red long-lasting phosphorescence of CaMgSi(2)O(6):Mn diopsides 
    Bessiere, A.; Lecointre, A.; Priolkar, K.R.; Gourier, D. (Journal of Materials Chemistry. 22(36); 2012; 19039-19046.)
    CaMgSi(2)O(6):Mn diopsides are used for in vivo long-lasting phosphorescence (LLP) imaging. Trapping defects involved in the LLP mechanism were investigated. On annealing Mn-doped diopsides at 1100 degrees C in an Ar-H-2 ...
  • Cauchy type generalizations of holomorphic mean value theorems 
    Mohapatra, A.N. (Electronic Journal of Differential Equations. 2012(184); 1-6.)
    We extend the results on the Mean Value Theorem obtained by Flett, Myers, Sahoo, Cakmak and Tiryaki to holomorphic functions.
  • On generalisation of some variants of Lagrange mean value theorem, Antarctica 
    Mohapatra, A.N. (Journal of Mathematics. 9(6); 2012; 481-491.)
  • Implementation of Gigabit Ethernet Standard using FPGA 
    Gad, V.R.; Gad, R.S.; Naik, G.M. (International Journal of Mobile Network Communications and Telematics (IJMNCT). 2(4); 2012; 31-44.)
    This paper presents the results of Gigabit Ethernet standard implementation in the FPGA device. The design uses Altera's Stratix-II GX device and supports data transfer rates of 10Mbps, 100Mpbs as well as 1Gbps. FPGA ...
  • FPGA System for preventing TCP SYN flood attack 
    Ghanti, S.; Naik, G.M. (International Journal of VLSI Design 3(1); 2012; 39-43.)
    Today it is very important that servers are to be well protected. In preventing server against arious network attacks such as DDOS attacks a preventive system needs to deal with various network conditions and it should ...
