Anomalous nodal many body density of states
The density of states is a basic quantity that students learn, when they learn how to describe free electrons in a solid. As the name suggests, it says how many electrons the material can accomodate at a certain energy value.
In a strongly correlated electron system such as high temperature superconductors, the equivalent quantity is the many body density of states, $\int d\vec k A(\vec k, \omega)$, where $A$ is the single particle spectral function, measured by ARPES.
