Bose metal near pair-density-wave order in a spin-orbit-coupled Kondo lattice
Piers Coleman, Aaditya Panigrahi, Alexei Tsvelik
We show that a three-dimensional superconductor with a non-Abelian SU(2) order parameter can support an extended resistive regime a Bose metal, in which transport is carried by bos…
Tractable model for a fractionalized Fermi liquid (FL) on a square lattice
Piers Coleman, Elio J. König, Aaditya Panigrahi +1
Motivated by the continued interest in Fermi-surface reconstruction without symmetry breaking, we present an analytically tractable microscopic model of a fractionalized Fermi liqu…
A Landau Theory for Pair Density Modulation in Fe(Te,Se) flakes
Po-Jui Chen, Piers Coleman
Motivated by recent scanning tunneling microscopy (STM) experiments reporting a pair-density modulation (PDM) in flakes of FeTeSe, we develop a Landau theory…
A microscopic model of fractionalized Fermi liquid
P. Coleman, A. Panigrahi, A. Tsvelik
In this short letter we identify a relationship between the Kondo lattice model formulated in Coleman {\it et.al}, Phys. Rev. Lett. {\bf 129}, 177601 (2022) and Ancilla Layer formu…
A higher dimensional generalization of the Kitaev spin liquid
Po-Jui Chen, Piers Coleman
We construct an exactly solvable model of a four-dimensional Kitaev spin liquid. The lattice structure is orthorhombic and each unit-cell contains six sublattice degrees of freedom…
