Soft modes in the complex Sachdev-Ye-Kitaev model
ORAL
Abstract
We discuss soft modes in the Sachdev-Ye-Kitaev model for complex fermions with large N flavors and a global U(1) charge.
The conserved charge leads to a compact scalar field in the effective action, from which
we derive the many-body density of states and extract the charge compressibility.
We compute the latter via three distinct numerical methods and obtain consistent results.
