Perturbative study of the Kitaev model with spontaneous time-reversal symmetry breaking
S. Dusuel, K. P. Schmidt, J. Vidal +1
We analyze the Kitaev model on the triangle-honeycomb lattice whose ground state has recently been shown to be a chiral spin liquid. We consider two perturbative expansions: the is…

Equivalence of critical scaling laws for many-body entanglement in the Lipkin-Meshkov-Glick model
R. Orus, S. Dusuel, J. Vidal
We establish a relation between several entanglement properties in the Lipkin-Meshkov-Glick model, which is a system of mutually interacting spins embedded in a magnetic field. We…

Creation and Manipulation of Anyons in the Kitaev Model
S. Dusuel, K. P. Schmidt, J. Vidal
We analyze the effect of local spin operators in the Kitaev model on the honeycomb lattice. We show, in perturbation around the isolated-dimer limit, that they create Abelian anyon…
