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…

Counter-diabatic driving in the classical -Fermi-Pasta-Ulam-Tsingou chain

Nik O. Gjonbalaj, David K. Campbell, Anatoli Polkovnikov

Shortcuts to adiabaticity (STAs) have been used to make rapid changes to a system while eliminating or minimizing excitations in the system's state. In quantum systems, these short…

Dynamical symmetry breaking through AI: The dimer self-trapping transition

G. P. Tsironis, G. D. Barmparis, D. K. Campbell

The nonlinear dimer obtained through the nonlinear Schr{ö}dinger equation has been a workhorse for the discovery the role nonlinearity plays in strongly interacting systems. While…

Analysis of a Casimir-driven Parametric Amplifier with Resilience to Casimir Pull-in for MEMS Single-Point Magnetic Gradiometry

Josh Javor, Zhancheng Yao, Matthias Imboden +2

The Casimir Force, a quantum mechanical effect, has been observed in several microelectromechanical systems (MEMS) platforms. Due to its extreme sensitivity to the separation of tw…

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…
