Power law specific heat divergence in Sr3Ru2O7

We present measurement and analysis of field‐dependent specific heat measurements on Sr3Ru2O7, showing that, at low temperatures, an incipient divergence is cut off by the formation of a new phase previously identified to show the transport properties of an electronic nematic. We discuss how to inte...

Description
Summary:We present measurement and analysis of field‐dependent specific heat measurements on Sr3Ru2O7, showing that, at low temperatures, an incipient divergence is cut off by the formation of a new phase previously identified to show the transport properties of an electronic nematic. We discuss how to interpret a specific heat divergence in a system with van Hove singularities, and caution against a simple‐minded comparison of experimentally determined power laws with the predictions of quantum critical theories.
