Microscopic theory of pair density waves in spin-orbit coupled Kondo lattice
Aaditya Panigrahi, Alexei Tsvelik, Piers Coleman
We demonstrate that the discommensuration between the Fermi surfaces of a conduction sea and an underlying spin liquid provides a natural mechanism for the spontaneous formation of…
Dual view of the Z-Gauged XY Model in 3D
Piers Coleman, Anatoly Kuklov, Alexei Tsvelik
The gauged neutral XY model is of long-standing interest both in the context of nematic order, and the study of fractionalization and superconductivity. This paper presents h…
Odd-parity superconductivity underpinned by antiferromagnetism in heavy fermion metal YbRhSi
Lev V. Levitin, Jan Knapp, Petra Knappová +13
Topological superconductors are essential elements of the periodic table of topological quantum matter. However, the relevant odd-parity spin-triplet superconductors are rare. We r…
Topological superconductivity in a spin-orbit coupled Kondo lattice
Zekun Zhuang, Piers Coleman
We consider the effect of spin-orbit coupling on a two-dimensional Kondo Lattice model, in which conduction electrons are antiferromagnetically coupled to a Yao-Lee spin liquid. Wh…
Topological Heavy Fermion Principle For Flat (Narrow) Bands With Concentrated Quantum Geometry
Jonah Herzog-Arbeitman, Jiabin Yu, Dumitru CÄlugÄru +8
We propose a general principle for the low-energy theory of narrow bands with concentrated Berry curvature and Fubini-Study metric in the form of a map to Anderson-"+" models compo…
