Dynamically stabilized spin superfluidity in frustrated magnets
نویسندگان
چکیده
We study the onset of spin superfluidity, namely coherent transport mediated by a topological texture, in frustrated exchange-dominated magnetic systems, engendered an external field. show that for typical device geometries used nonlocal magnetotransport experiments, field stabilizes superflow against fluctuations, up to critical current. For given current, depends on precessional frequency which can be separately controlled. contrast such dynamic stabilization superfluid conventional approaches based stabilization.

Hall effect of spin waves in frustrated magnets.
We examine a possible spin Hall effect for localized spin systems with no charge degrees of freedom. In this scenario, a longitudinal magnetic field gradient induces a transverse spin current carried by spin wave excitations with an anomalous velocity which is caused by a topological Berry-phase effect associated with spin chirality, in analogy with anomalous Hall effects in itinerant electron ...
متن کاملSpin-charge separation in two-dimensional frustrated quantum magnets.
The dynamics of a mobile hole in two-dimensional frustrated quantum magnets is investigated by exact diagonalization techniques. Our results provide evidence for spin-charge separation upon doping the kagome lattice, a prototype of a spin liquid. In contrast, in the checkerboard lattice, a symmetry broken valence bond crystal, a small quasiparticle peak is seen for some crystal momenta, a findi...
متن کاملSpin-Ice and Other Frustrated Magnets on the Pyrochlore Lattice
The recent identification of the dysprosium titanate compound Dy2T i2O7 as a “Spin-Ice”, i.e. the spin analog of regular entropic ice of Pauling, has created considerable excitement. The ability to manipulate spins using magnetic fields gives a unique advantage over regular ice in these systems, and has been used to study the recovery of entropy. Predicted magnetization plateaus have been obser...
متن کاملFrustrated Quantum Magnets
A description of different phases of two dimensional magnetic insulators is given. The first chapters are devoted to the understanding of the symmetry breaking mechanism in the semi-classical Néel phases. Order by disorder selection is illustrated. All these phases break SU(2) symmetry and are gapless phases with ∆Sz = 1 magnon excitations. Different gapful quantum phases exist in two dimension...
متن کاملSpin-nematic and spin-density-wave orders in spatially anisotropic frustrated magnets in a magnetic field.
We develop a microscopic theory of finite-temperature spin-nematic orderings in three-dimensional spatially anisotropic magnets consisting of weakly coupled frustrated spin-1/2 chains with nearest-neighbor and next-nearest-neighbor couplings in a magnetic field. Combining a field theoretical technique with density-matrix renormalization group results, we complete finite-temperature phase diagra...
