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 Călugăru +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…
