Quantum Electrodynamics in a Uniform Magnetic Field
A systematic formalism for quantum electrodynamics in a classical uniform magnetic field is discussed. The first order radiative correction to the ground state energy of an electron is calculated. This then leads to the anomalous magnetic moment of an electron without divergent integrals. Thorough analyses of this problem are given for the weak magnetic field limit. A new expression for the rad...

متن کاملNanofluid Flow in a Semi-porous Channel in the Presence of Uniform Magnetic Field
In this paper, the problem of laminar nanofluid flow in a semi-porous channel is investigated analytically using Homotopy Perturbation Method (HPM). This problem is in the presence of transverse magnetic field. Here, it has been attempted to show the capabilities and wide-range applications of the Homotopy Perturbation Method in comparison with the numerical method in solving such problems. The...
متن کاملStudy of Chemically Reactive Flow and Heat Transfer in the Presence of a Uniform Magnetic Field
The effects of chemical reaction, thermal stratification, Soret and Dufour numbers on magneto-hydrodynamic free convective heat and mass transfer of a viscous, incompressible,and electrically conducting fluid on a vertical stretching surface embedded in a saturated porous medium are presented. A similarity transform is used to reduce the governing partial differential equations into a syste...
متن کاملMagnetic-Field Induced Quantum Phase Transitions in Triangular-Lattice Antiferromagnets
Cs2CuBr4 and Ba3NiSb2O9 are magnetically described as quasi-two-dimensional triangular-lattice antiferromagnets with spin1 2 and 1, respectively. We show that both systems exhibit a magnetization plateau at one-third of the saturation magnetization Ms due to the interplay of spin frustration and quantum fluctuation. In Cs2CuBr4 that has a spatially anisotropic triangular lattice, successive mag...
