Two-channel Kondo physics in two-impurity Kondo models
Andrew K. Mitchell, Eran Sela, David E. Logan
We consider the non-Fermi liquid quantum critical state of the spin-S two-impurity Kondo model, and its potential realization in a quantum dot device. Using conformal field theory…
Majorana Fermions in Strongly Interacting Helical Liquids
Eran Sela, Alexander Altland, Achim Rosch
Majorana fermions were proposed to occur at edges and interfaces of gapped one-dimensional systems where phases with different topological character meet due to an interplay of spi…
Orbital multicriticality in spin gapped quasi-1D antiferromagnets
Eran Sela, R. G. Pereira
Motivated by the quasi-1D antiferromagnet CaVO, we explore spin-orbital systems in which the spin modes are gapped but orbitals are near a macroscopically degenerate classi…
Exact crossover Green function in the two-channel and two-impurity Kondo models
Eran Sela, Andrew K. Mitchell, Lars Fritz
Symmetry-breaking perturbations destabilize the critical points of the two-channel and two-impurity Kondo models, thereby leading to a crossover from non-Fermi liquid behavior to s…
