Application of Generalized Periodic Anderson Hamiltonians to the Superconducting Nickelates
Abhishek Som, Nahom K. Yirga, David K. Campbell
We study the extent to which a three-dimensional dispersing Periodic Anderson Model (PAM) can explain the emergence of novel superconductivity in the Infinite-Layer Nickelate compo…

Phonon Induced Instabilities in Correlated Electron Hamiltonians
Nahom K. Yirga, Ka-Ming Tam, David K. Campbell
Studies of Hamiltonians modeling the coupling between electrons as well as to local phonon excitations have been fundamental in capturing the novel ordering seen in many quasi-one…

Frequency Dependent Functional Renormalization Group for Interacting Fermionic Systems
Nahom K. Yirga, David K. Campbell
We derive an expansion of the functional renormalization (fRG) equations that treats the frequency and momentum dependencies of the vertices in a systematic manner. The scheme exte…
