Theory of Helimagnons in Itinerant Quantum Systems IV: Transport in the Weak-Disorder Regime
T. R. Kirkpatrick, D. Belitz, Ronojoy Saha
We apply a recent quasiparticle model for the electronic properties of metallic helimagnets to calculate the transport properties of three-dimensional systems in the helically orde…
Theory of Helimagnons in Itinerant Quantum Systems III: Quasiparticle Description
T. R. Kirkpatrick, D. Belitz, Ronojoy Saha
In two previous papers we studied the problem of electronic properties in a system with long-ranged helimagnetic order caused by itinerant electrons. A standard many-fermion formal…
Analogy between Three-Dimensional Helimagnetic Metals and Two-Dimensional Nonmagnetic Metals: Transport in the Weak-Disorder Regime
T. R. Kirkpatrick, D. Belitz, Ronojoy Saha
We present a quasi-particle model that allows for a simple description of the electronic properties of metallic helimagnets. For weak quenched disorder, we find a leading linear te…
Theory of helimagnons in itinerant quantum systems II: Nonanalytic corrections to Fermi-liquid behavior
D. Belitz, T. R. Kirkpatrick, A. Rosch
A recent theory for the ordered phase of helical or chiral magnets such as MnSi is used to calculate observable consequences of the helical Goldstone modes or helimagnons. In syste…
Theory of helimagnons in itinerant quantum systems
D. Belitz, T. R. Kirkpatrick, A. Rosch
The nature and effects of the Goldstone mode in the ordered phase of helical or chiral itinerant magnets such as MnSi are investigated theoretically. It is shown that the Goldstone…
Nonanalytic Corrections to Fermi-Liquid Behavior in Helimagnets
T. R. Kirkpatrick, D. Belitz
The Goldstone mode in the ordered phase of itinerant helimagnets, such as MnSi or FeGe, is determined and shown to have a strongly anisotropic dispersion relation. The softness of…
