Conductance fingerprint of Majorana fermions in the topological Kondo effect
Martin R. Galpin, Andrew K. Mitchell, Jesada Temaismithi +3
We consider an interacting nanowire/superconductor heterostructure attached to metallic leads. The device is described by an unusual low-energy model involving spin-1 conduction el…
Quantum phase transitions and thermodynamics of the power-law Kondo model
Andrew K. Mitchell, Matthias Vojta, Ralf Bulla +1
We revisit the physics of a Kondo impurity coupled to a fermionic host with a diverging power-law density of states near the Fermi level, , with exponent .…
Generalized Wilson Chain for solving multichannel quantum impurity problems
Andrew K. Mitchell, Martin R. Galpin, Samuel Wilson-Fletcher +2
The Numerical Renormalization Group is used to solve quantum impurity problems, which describe magnetic impurities in metals, nanodevices, and correlated materials within DMFT. Her…
Local moment formation and Kondo screening in impurity trimers
Andrew K. Mitchell, Thomas F. Jarrold, Martin R. Galpin +1
We study theoretically a triangular cluster of three magnetic impurities, hybridizing locally with conduction electrons of a metallic host. Such a cluster is the simplest to exhibi…
