Generalization of the Haldane conjecture to SU() chains
Kyle Wamer, Miklós Lajkó, Frédéric Mila +1
Recently, SU(3) chains in the symmetric and self-conjugate representations have been studied using field theory techniques. For certain representations, namely rank- symmetric o…
Phase diagram of the spin-1/2 Kitaev-Gamma chain and emergent SU(2) symmetry
Wang Yang, Alberto Nocera, Tarun Tummuru +2
We study the phase diagram of a one-dimensional version of the Kitaev spin-1/2 model with an extra ``-term", using analytical, density matrix renormalization group and exact dia…
Kondo effect due to a hydrogen impurity in graphene: a multichannel Kondo problem with diverging hybridization
Zheng Shi, Emilian M. Nica, Ian Affleck
We consider the Kondo effect arising from a hydrogen impurity in graphene. As a first approximation, the strong covalent bond to a carbon atom removes that carbon atom without brea…
Self-conjugate representation SU(3) chains
Kyle Wamer, Francisco H. Kim, Miklós Lajkó +2
It was recently argued that SU(3) chains in the -box symmetric irreducible representation (irrep) exhibit a "Haldane gap" when is a multiple of 3 and are otherwise gapless […
Novel families of AKLT states with arbitrary self-conjugate edge states
Samuel Gozel, Didier Poilblanc, Ian Affleck +1
Using the Matrix Product State framework, we generalize the Affleck-Kennedy-Lieb-Tasaki (AKLT) construction to one-dimensional spin liquids with global color symmetry…
Real fermion modes, impurity entropy, and nontrivial fixed points in the phase diagram of junctions of interacting quantum wires and topological superconductors
Domenico Giuliano, Ian Affleck
We discuss how to extend the impurity entropy to systems with boundary interactions depending on zero-mode real fermion operators (Majorana modes as well as Klein factors). As spec…
