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…
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…
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…
Breakdown of order-fractionalization in the CPT model
Aaditya Panigrahi, Alexei Tsvelik, Piers Coleman
We present an analysis of the half-filled CPT model, an analytically tractable Kondo lattice model with Yao-Lee spin-spin interactions on a 3D hyperoctagon lattice, proposed by Col…
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…
Flat bands, strange metals, and the Kondo effect
Joseph G. Checkelsky, B. Andrei Bernevig, Piers Coleman +2
Flat band materials such as the kagome metals or moiré superlattice systems are of intense current interest. Flat bands can result from the electron motion on numerous (special) la…
Origin of the Large Anisotropy in the χ_3 Anomaly in URu_2Si_2
Premala Chandra, Piers Coleman, Rebecca Flint
Motivated by recent quantum oscillations experiments on URu_2Si_2, we discuss the microscopic origin of the large anisotropy observed many years ago in the anomaly of the nonlinear…
Breakdown of the Chiral Luttinger Liquid in One-Dimension
A. F. Ho, P. Coleman
We have developed a fermionic boot-strap method to solve a class of chiral one dimensional fermion model which cannot be tackled by bosonization. Using this scheme, we show that Lu…
Marginal Fermi Liquid in a lattice of three-body bound-states
A. F. Ho, P. Coleman
We study a lattice model for Marginal Fermi liquid behavior, involving a gas of electrons coupled to a dense lattice of three-body bound-states. The bound-states change the phase s…
