Four-point function of the complex Sachdev-Ye-Kitaev model at finite chemical potential
Can Onur Akyuz, Erick Arguello Cruz, Ludo Fraser-Taliente +1
It is known that, for a range of chemical potentials, the infrared behavior of the complex Sachdev-Ye-Kitaev (cSYK) model is governed by a 1D Nearly Conformal Field Theory (NCFT$_{…

Effective Description of Ajar Systems with a Symmetry
Can Onur Akyuz, Riccardo Penco
We introduce the concept of "ajar systems" as an intermediate case between closed and open systems, where the time scale for charge exchange with the environment is parametrically…

The Schwinger-Keldysh Coset Construction
Can Onur Akyuz, Garrett Goon, Riccardo Penco
The coset construction is a tool for systematically building low energy effective actions for Nambu-Goldstone modes. This technique is typically used to compute time-ordered correl…
