SO(5) critical point in a spin-flavor Kondo device -- Bosonization and refermionization solution
Alon Liberman, Andrew K. Mitchell, Ian Affleck +1
We investigate a well studied system of a quantum dot coupled to a Coulomb box and leads, realizing a spin-flavor Kondo model. It exhibits a recently discovered non-Fermi liquid (N…

SO(5) non-Fermi liquid in a Coulomb box device
Andrew K. Mitchell, Alon Liberman, Eran Sela +1
Non-Fermi liquid (NFL) physics can be realized in quantum dot devices where competing interactions frustrate the exact screening of dot spin or charge degrees of freedom. We show t…
