Linear Magnetoresistance from Glassy Orders
arxiv(2024)
摘要
Several strongly correlated metals display B-linear magnetoresistance (LMR)
with a universal slope, in sharp contrast to the B^2 scaling predicted by
Fermi liquid theory. We provide a unifying explanation of the origin of LMR by
focusing on a common feature in their phase diagrams – proximity to
symmetry-breaking orders. Specifically, we demonstrate via two microscopic
models that LMR with a universal slope arises ubiquitously near ordered phases,
provided the order parameter either (i) has a finite wave-vector, or (ii) has
nodes on the Fermi surface. We elucidate the distinct physical mechanisms at
play in these two scenarions, and derive upper and lower bounds on the field
range for which LMR is observed. Finally, we discuss possible extensions of our
picture to strange metal physics at higher temperatures, and argue that our
theory provides an understanding of recent experimental results on thin film
cuprates and moiré materials.
