Mott transitions in the Periodic Anderson Model
David E. Logan, Martin R. Galpin, Jonathan Mannouch
The periodic Anderson model (PAM) is studied within the framework of dynamical mean-field theory, with particular emphasis on the interaction-driven Mott transition it contains, an…
Mott insulators and the doping-induced Mott transition within DMFT: exact results for the one-band Hubbard model
David E. Logan, Martin R. Galpin
The paramagnetic phase of the one-band Hubbard model is studied at zero-temperature, within the framework of dynamical mean-field theory, and for general particle-hole asymmetry wh…
Common non-Fermi liquid phases in quantum impurity physics
David E. Logan, Adam P. Tucker, Martin R. Galpin
We study correlated quantum impurity models which undergo a local quantum phase transition (QPT) from a strong coupling, Fermi liquid phase to a non-Fermi liquid phase with a globa…
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…
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…
