Kondo breakdown in a spin-1/2 chain of adatoms on a Dirac semimetal
Bimla Danu, Matthias Vojta, Fakher F. Assaad +1
We consider a spin-1/2 Heisenberg chain coupled via a Kondo interaction to two-dimensional Dirac fermions. The Kondo interaction is irrelevant at the \textit{decoupled} fixed-point…

Exploring the Kondo effect of an extended impurity with chains of Co adatoms in a magnetic field
Bimla Danu, Fakher Assaad, Frédéric Mila
Motivated by recent STM experiments, we explore the magnetic field induced Kondo effect that takes place at symmetry protected level crossings in finite Co adatom chains. We argue…

DMRG studies on linear-exchange quantum spin models in one dimension
Bimla Danu, Brijesh Kumar, Ramesh V. Pai
We study a class of spin-1/2 quantum antiferromagnetic chains using DMRG technique. The exchange interaction in these models decreases linearly as a function of the separation betw…
