Theories for charge-driven nematicity in kagome metals
Nematicity, the broken rotational symmetry of a lattice's point group, is often linked to unconventional superconductivity. This work presents two theories for the nematic behavior in kagome metals. One theory suggests a $d$-wave charge Pomeranchuk instability, while the other attributes nematicity to fluctuations in one-dimensional charge order observed experimentally. Unlike iron-based superconductors, where spin-fluctuations drive nematicity, the kagome metals' nematic tendencies are likely induced by charge fluctuations, offering a distinct mechanism for this behavior.
