Quantum solitons in the sawtooth lattice.
We study the sawtooth lattice of a coupled spin 1/2 Heisenberg system, a variant of the railroad-trestle lattice. The ground state of this system is twofold degenerate with periodic boundary conditions and supports kink-antikink excitations, which are distinct in this case, unlike the railroad-trestle lattice. The resulting lowtemperature thermodynamics is compared with the recently discovered ...
متن کاملQuantum 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 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...
متن کاملLattice Instability in the Spin - Ladder System under Magnetic Field
We study theoretically the lattice instability in the spin gap systems under magnetic field. With the magnetic field larger than a critical value hc1, the spin gap is collapsed and the magnetization arises. We found that the lattice distortion occurs in the spin-ladder at an incommensurate wavevector corresponding to the magnetization, while it does not occur in the Haldane system. At low tempe...
متن کاملDynamics of ferrofluid drop deformations under spatially uniform magnetic fields
We systematically study the shape and dynamics of a Newtonian ferrofluid drop immersed in an immiscible, Newtonian and non-magnetic viscous fluid under the action of a uniform external magnetic field. We obtain the exact equilibrium drop shapes for arbitrary ferrofluids, characterize the extent of deviations of the exact shape from the commonly assumed ellipsoidal shape, and analyse the smoothn...
