Diagrammatic quantum field formalism for localized electrons
S. A. Bonev, N. W. Ashcroft
We introduce a diagrammatic quantum field formalism for the evaluation of normalized expectation values of operators, and suitable for systems with localized electrons. It is used…

Violation of the London Law and Onsager-Feynman quantization in multicomponent superconductors
Egor Babaev, N. W. Ashcroft
Non-classical response to rotation is a hallmark of quantum ordered states such as superconductors and superfluids. The rotational responses of all currently known single-component…

Nonlinear response theories and effective pair potentials
Simon Gravel, N. W. Ashcroft
We present a general method based on nonlinear response theory to obtain effective interactions between ions in an electron gas which can also be applied to other systems where an…
