Kondo effect in the isotropic Heisenberg spin chain

P Kattel, PR Pasnoori, JH Pixley, P Azaria, N Andrei - Physical Review B, 2024 - APS
We investigate the boundary effects that arise when spin-1 2 impurities interact with the
edges of the antiferromagnetic spin-1 2 Heisenberg chain through spin exchange …
