Explicit diagrammatic solution of normalised, nondegenerate Rayleigh-Schrödinger perturbation theory
Joel C. Pommerening, David P. DiVincenzo
We solve the coupled recurrence relations for eigenenergies and -vectors in nondegenerate Rayleigh-Schrödinger perturbation theory under the constraint that the approximate eigenve…

What is measured when a qubit measurement is performed on a multi-qubit chip?
Joel C. Pommerening, David P. DiVincenzo
We study how single-qubit dispersive readout works alongside two qubit coupling. To make calculations analytically tractable, we use a simplified model which retains core character…

Small quenches and thermalization
D. M. Kennes, J. C. Pommerening, J. Diekmann +2
We study the expectation values of observables and correlation functions at long times after a global quantum quench. Our focus is on metallic (`gapless') fermionic many-body model…
