Kondo effect with diverging hybridization: possible realization in graphene with vacancies
Andrew K. Mitchell, Lars Fritz
We investigate Kondo physics in a host with a strongly diverging density of states. This study is motivated by a recent work on vacancies in the graphene honeycomb lattice, whose d…
Kondo effect on the surface of 3D topological insulators: Signatures in scanning tunneling spectroscopy
Andrew K. Mitchell, Dirk Schuricht, Matthias Vojta +1
We investigate the scattering off dilute magnetic impurities placed on the surface of three-dimensional topological insulators. In the low-temperature limit, the impurity moments a…
Universal low-temperature crossover in two-channel Kondo models
Andrew K. Mitchell, Eran Sela
An exact expression is derived for the electron Green function in two-channel Kondo models with one and two impurities, describing the crossover from non-Fermi liquid (NFL) behavio…
Local Magnetization in the Boundary Ising Chain at Finite Temperature
Eran Sela, Andrew K. Mitchell
We study the local magnetization in the 2-D Ising model at its critical temperature on a semi-infinite cylinder geometry, and with a nonzero magnetic field applied at the circu…
