Non-local String Order Parameter in the Kitaev-Heisenberg Ladder
Andrei Catuneanu, Erik S. Sørensen, Hae-Young Kee
We study the spin- Kitaev-Heisenberg (KJ) model in a two-leg ladder. Without a Heisenberg interaction, the Kitaev phase in the ladder model has Majorana fermions with…

Counter-rotating spiral order in three dimensional iridates: signature of hidden symmetry in Kitaev- model
Panagiotis Peter Stavropoulos, Andrei Catuneanu, Hae-Young Kee
The unconventional magnetic orderings found in Kitaev spin liquid candidates suggest frustration of spin interactions, and raise a possibility of nearby spin liquid phases. In part…
