Anomalous Transport Behavior in Quantum Magnets

Abstract

Transport behavior characterized by a low-temperature electrical resistivity that displays a power-law behavior $\rho (T\to 0)\propto T^s$ with an exponent $s<2$, is commonly observed in magnetic materials in both the magnetic and nonmagnetic phases. We give a pedagogical overview of this phenomenon that summarizes both the experimental situation and the state of its theoretical understanding. We also put it in context by drawing parallels with unusual power-law transport behavior in other systems.
