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 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…
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…
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…
High-temperature quantum coherence of spinons in a rare-earth spin chain
Lazar L. Kish, Andreas Weichselbaum, Daniel M. Pajerowski +6
Conventional wisdom dictates that quantum effects become unimportant at high temperatures. In magnets, when the thermal energy exceeds interactions between atomic magnetic moments,…
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…
Spinon Confinement and a Sharp Longitudinal Mode in YbPtPb in Magnetic Fields
W. J. Gannon, I. A. Zaliznyak, L. S. Wu +7
The fundamental excitations in an antiferromagnetic chain of spins-1/2 are spinons, de-confined fractional quasiparticles that when combined in pairs, form a triplet excitation con…
Tomonaga-Luttinger Liquid Behavior and Spinon Confinement in YbAlO
L. S. Wu, S. E. Nikitin, Z. Wang +14
Low dimensional quantum magnets are interesting because of the emerging collective behavior arising from strong quantum fluctuations. The one-dimensional (1D) S = 1/2 Heisenberg an…
Two-leg SU(2n) spin ladder: A low-energy effective field theory approach
P. Lecheminant, A. M. Tsvelik
We present a field theory analysis of a model of two SU(2n)-invariant magnetic chains coupled by a generic interaction preserving time reversal and inversion symmetry. Contrary to…
