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…
Specific heat of a one-dimensional interacting Fermi system: the role of anomalies
Andrey V. Chubukov, Dmitrii L. Maslov, Ronojoy Saha
We re-visit the issue of the temperature dependence of the specific heat C(T) for interacting fermions in 1D. The charge component C_c(T) scales linearly with T, but the spin compo…
Criticality in inhomogeneous magnetic systems: Application to quantum ferromagnets
D. Belitz, T. R. Kirkpatrick, Ronojoy Saha
We consider a -theory with a position-dependent distance from the critical point. One realization of this model is a classical ferromagnet subject to non-uniform mechanical st…
Phase-ordering dynamics in itinerant quantum ferromagnets
D. Belitz, T. R. Kirkpatrick, Ronojoy Saha
The phase-ordering dynamics that result from domain coarsening are considered for itinerant quantum ferromagnets. The fluctuation effects that invalidate the Hertz theory of the qu…
