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…
Observability of a projected new state of matter: a metallic superfluid
Egor Babaev, Asle Sudbo, N. W. Ashcroft
Dissipationless quantum states, such as superconductivity and superfluidity, have attracted interest for almost a century. A variety of systems exhibit these macroscopic quantum ph…
A superconductor to superfluid phase transition in liquid metallic hydrogen
Egor Babaev, Asle Sudbo, N. W. Ashcroft
Although hydrogen is the simplest of atoms, it does not form the simplest of solids or liquids. Quantum effects in these phases are considerable (a consequence of the light proton…
