Exponent relations at quantum phase transitions, with applications to metallic quantum ferromagnets
T. R. Kirkpatrick, D. Belitz
Relations between critical exponents, or scaling laws, at both continuous and discontinuous quantum phase transitions are derived and discussed. In general there are multiple dynam…
Electronic Transport at Low Temperatures: Diagrammatic Approach
D. Belitz, T. R. Kirkpatrick
We prove that a diagrammatic evaluation of the Kubo formula for the electronic transport conductivity due the exchange of bosonic excitations, in the usual conserving ladder approx…
Breakdown of Hydrodynamic Transport Theory in the Ordered Phase of Helimagnets
T. R. Kirkpatrick, D. Belitz
It is shown that strong fluctuations preclude a hydrodynamic description of transport phenomena in helimagnets, such as MnSi, at T>0. This breakdown of hydrodynamics is analogous t…
Electrons in an annealed environment: A special case of the interacting electron problem
D. Belitz, T. R. Kirkpatrick
The problem of noninteracting electrons in the presence of annealed magnetic disorder, in addition to nonmagnetic quenched disorder, is considered. It is shown that the proper phys…
Absence of electron dephasing at zero temperature
T. R. Kirkpatrick, D. Belitz
Dephasing of electrons due to the electron-electron interaction has recently been the subject of a controversial debate, with different calculations yielding mutually incompatible…
Superconductivity and Quantum Phase Transitions in Weak Itinerant Ferromagnets
T. R. Kirkpatrick, Thomas Vojta, D. Belitz +1
It is argued that the phase transition in low-T_c clean itinerant ferromagnets is generically of first order, due to correlation effects that lead to a nonanalytic term in the free…
