Nematic fluctuations in the Hubbard models

ORAL

Abstract

An electron nematic is an electronic phase with translation symmetry, but broken rotational symmetry. Signatures of nematic fluctuations have been observed in strongly correlated materials such as cuprates, iron pnictide, and iron chalcogenide superconductors, and may be related with other sorts of broken symmetries such as charge or spin density waves. Here we report calculations of the nematic susceptibilities from determinant quantum Monte Carlo (DQMC) simulations of the Hubbard models, for various model parameters, doping levels, and temperatures. We draw possible connections between these susceptibilities to other phenomena observed in the Hubbard model.
