      Analytic models of heterogenous magnetic fields for liquid metal flow simulations 

      Votyakov, E. V.; Kassinos, Stavros C.; Albets-Chico, X. (2009)
      A physically consistent approach is considered for defining an external magnetic field as needed in computational fluid dynamics problems involving magnetohydrodynamics (MHD). The approach results in simple analytical ...

      Coulomb repulsive correlation in A3B5 semiconductor quantum dots in the presence of a magnetic field 

      Avetisyan, A. A.; Djotyan, Anahit P.; Moulopoulos, Konstantinos (2006)
      The ground state total and correlation energies of a negative ion-electron and electron-electron systems in a parabolic QD with standard dispersion law are theoretically investigated in an external magnetic field by a ...

      Few-electron systems in a quantum dot in a magnetic field: The Wigner molecule and paired electron phases 

      Avetisyan, A. A.; Moulopoulos, Konstantinos (2006)
      We have developed a variational many-body description for few-electron systems in a parabolic quantum dot in an external magnetic field. The ground state energy of the electronic system has been theoretically investigated ...

      Laminar free convection in a square enclosure driven by the Lorentz force 

      Sarris, I. E.; Grigoriadis, D. G. E.; Vlachos, N. S. (2010)
      A numerical study is presented of laminar free convection flow driven by magnetic forces. An external magnetic field with one spatially varying component is applied to an electrically conducting fluid in a square enclosure. ...

      Magneto-transport properties of NiMnSb thin films on InSb single crystals: Negative giant magnetoresistance 

      Gardelis, S.; Androulakis, J.; Viskadourakis, Z.; Papadopoulou, E. L.; Giapintzakis, John; Rai, S.; Lodha, G. S.; Roy, S. B. (2007)
      In this study we investigated the magneto-transport properties of the ohmic contact between polycrystal-line NiMnSb thin films grown by pulsed laser deposition and n-type degenerate InSb (100) substrates. An unusual negative ...

      Magnetoresponsive polymer networks as adsorbents for the removal of U(VI) ions from aqueous media 

      Ilia, R.; Liatsou, I.; Savva, I.; Vasile, E.; Vekas, L.; Marinica, O.; Mpekris, F.; Pashalidis, I.; Krasia-Christoforou, T. (2017)
      Magnetoresponsive, methacrylate-based 3D polymer networks containing hydrophilic/thermoresponsive, hydrophilic/pH-responsive and hydrophobic/metal chelating functionalities and oleic acid-coated magnetite nanoparticles, ...

      MHD flow past a circular cylinder using the immersed boundary method 

      Grigoriadis, D. G. E.; Sarris, I. E.; Kassinos, Stavros C. (2010)
      The immersed boundary method (IB hereafter) is an efficient numerical methodology for treating purely hydrodynamic flows in geometrically complicated flow-domains. Recently Grigoriadis et als. [1] proposed an extension of ...

      Structure anisotropy in MHD turbulence subjected to mean shear and frame rotation 

      Kassinos, Stavros C.; Wray, A. (Affiliation: Dept. of Mechanical and Manufacturing Engineering, University of Cyprus, Nicosia, CyprusAffiliation: Department of Mechanical Engineering, Stanford University, Stanford, CA 94305, United StatesAffiliation: Center for Turbulence Research, NASA Ames Research Center, United StatesCorrespondence Address: Kassinos, S.C.Dept. of Mechanical and Manufacturing Engineering, University of Cyprus, Nicosia, Cyprusemail: kassinos@ucy.ac.cy, 2005)
      We consider homogeneous turbulence in a conducting fluid that is exposed to a uniform external magnetic field while being sheared in fixed and rotating frames. We take both the frame-rotation axis and the applied magnetic ...

      Thermodynamic properties of QCD in external magnetic fields 

      Bali, G. S.; Bruckmann, F.; Constantinou, Martha; Costa, Marios Gil; Endrödi, Gergely; Fodor, Zoltán; Katz, Sándor D.; Krieg, S.; Panagopoulos, Haralambos G.; Schäfer, A.; Szabó, Kálmán K. (2012)
      We consider the effect of strong external electromagnetic fields on thermodynamic observables in QCD, through lattice simulations with 1+1+1 flavors of staggered quarks at physical quark masses. Continuum extrapolated ...
