Ising nematic quantum critical point in a metal: a Monte Carlo study

Understand

The Ising nematic quantum critical point (QCP) associated with the zero temperature transition from a symmetric to a nematic {\it metal} is an exemplar of metallic quantum criticality.

• We have carried out a minus sign-free quantum Monte Carlo study of this QCP for a two dimensional lattice model with sizes up to $24\times 24$ sites.
• The system remains non-superconducting down to the lowest accessible temperatures.
• The results exhibit critical scaling behavior over the accessible ranges of temperature, (imaginary) time, and distance.
