Dynamical scaling as a signature of multiple phase competition in YbTiO
Allen Scheie, Owen Benton, Mathieu Taillefumier +5
is a celebrated example of a pyrochlore magnet with highly-frustrated, anisotropic exchange interactions. To date, attention has largely focused on its unusual, s…
Competing spin liquids and hidden nematic order in spin ice with frustrated transverse exchange
Mathieu Taillefumier, Owen Benton, Han Yan +2
Frustration in magnetic interactions can give rise to disordered ground states with subtle and beautiful properties. The spin ices Ho2Ti2O7 and Dy2Ti2O7 exemplify this phenomenon,…
Semi-classical spin dynamics of the antiferromagnetic Heisenberg model on the kagome lattice
Mathieu Taillefumier, Julien Robert, Christopher L. Henley +2
We investigate the dynamical properties of the classical antiferromagnetic Heisenberg model on the kagome lattice using a combination of Monte Carlo and molecular dynamics simulati…
Chiral two-dimensional electron gas in a periodic magnetic field
Mathieu Taillefumier, Vitalii Dugaev, Benjamin Canals +2
We study the energy spectrum and electronic properties of two-dimensional electron gas in a periodic magnetic field of zero average with a symmetry of triangular lattice. We demons…
Anomalous Hall Effect due to the spin chirality in the Kagomé lattice
Mathieu Taillefumier, Benjamin Canals, Claudine Lacroix +2
We consider a model for a two dimensional electron gas moving on a kagomé lattice and locally coupled to a chiral magnetic texture. We show that the transverse conductivity $σ\_{xy…
