Kondo impurities in the Kitaev spin liquid: Numerical renormalization group solution and gauge-flux-driven screening
Matthias Vojta, Andrew K. Mitchell, Fabian Zschocke
Kitaev's honeycomb-lattice compass model describes a spin liquid with emergent fractionalized excitations. Here we study the physics of isolated magnetic impurities coupled to the…
Interleaved numerical renormalization group as an efficient multiband impurity solver
K. M. Stadler, A. K. Mitchell, J. von Delft +1
Quantum impurity problems can be solved using the numerical renormalization group (NRG), which involves discretizing the free conduction electron system and mapping to a `Wilson ch…
Universality and scaling in a charge two-channel Kondo device
Andrew K. Mitchell, L. A. Landau, L. Fritz +1
We study a charge two-channel Kondo model, demonstrating that recent experiments [Iftikhar et al, Nature 526, 233 (2015)] realize an essentially perfect quantum simulation -- not j…
