Incommensurate Spiral Order from Double-Exchange Interactions. [PDF]
Physical Review Letters, 2016 The double-exchange model describing interactions of itinerant electrons with localized spins is usually used to explain ferromagnetism in metals. We show that for a variety of crystal lattices of different dimensionalities and for a wide range of model ...

Quantum phase transition in the Plaquette lattice with anisotropic spin exchange [PDF]
, 2003 I study the influence of anisotropic spin exchange on a quantum phase transition in the Plaquette lattice driven by the purely quantum effect of singlet formation. I study the influence of i) a Dzyaloshinskii-Moriya exchange and ii) four spin exchange on

Octupolar Order in the Multiple Spin Exchange Model on a Triangular Lattice [PDF]
, 2006 We show how a gapless spin liquid with hidden octupolar order arises in an applied magnetic field, in a model applicable to thin films of 3He with competing ferromagnetic and antiferromagnetic (cyclic) exchange interactions.

Analysis of the second-order exchange self-energy of a dense electron gas [PDF]
, 2006 We evaluate the six-fold integral representation for the second-order exchange contribution to the self-energy of a dense three-dimensional electron gas on the Fermi surface.

Reverse Exchangeability and Extreme Order Statistics [PDF]
, 2013 For a bivariate random vector (X,Y), symmetry conditions are presented that yield stochastic orderings among |X|, |Y|, |max(X,Y)|, and | min(X, Y)|. Partial extensions of these results for multivariate random vectors (X1,...,Xn) are also given.

Doping change and distortion effect on double-exchange ferromagnetism [PDF]
Phys. Rev. B 72, 214418 (2005), 2005 Doping change and distortion effect on the double-exchange ferromagnetism are studied within a simplified double-exchange model. The presence of distortion is modelled by introducing the Falicov-Kimball interaction between itinerant electrons and ...

Journal the Winners, 2012 Numerous empirical studies in the finance field have tested many theories for firms’ capital structure. The pecking order theory and the trade-off theory of capital structure is among the most influential theories of firms’ capital structure.

Equivalence of Nonstatic Two-Pion-Exchange Nucleon-Nucleon Potentials [PDF]
Phys.Rev.C60:034002,1999, 1999 Off-shell aspects of the one-pion-exchange potential and their relationship to different forms of the nonstatic (subleading-order) chiral two-pion-exchange nucleon-nucleon potential are discussed.
