The Heart of Entanglement: Chiral, Nematic, and Incommensurate Phases in the Kitaev-Gamma Ladder in a Field
Erik S. Sørensen, Andrei Catuneanu, Jacob Gordon +1
The bond-dependent Kitaev model on the honeycomb lattice with anyonic excitations has recently attracted considerable attention. However, in solid state materials other spin intera…
Honeycomb-Lattice Mott insulator on Tantalum Disulphide
Jinwon Lee, Kyung-Hwan Jin, Andrei Catuneanu +8
Effects of electron many-body interactions amplify in an electronic system with a narrow bandwidth opening a way to exotic physics. A narrow band in a two-dimensional (2D) honeycom…
Theory of the field-revealed Kitaev spin liquid
Jacob S. Gordon, Andrei Catuneanu, Erik S. Sørensen +1
Elementary excitations in highly entangled states such as quantum spin liquids may exhibit exotic statistics, different from those obeyed by fundamental bosons and fermions. Excita…
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…
Path to stable quantum spin liquids in spin-orbit coupled correlated materials
Andrei Catuneanu, Youhei Yamaji, Gideon Wachtel +2
The spin liquid phase is one of the prominent strongly interacting topological phases of matter whose unambiguous confirmation is yet to be reached despite intensive experimental e…
Topological edge states in single layers of honeycomb materials with strong spin-orbit coupling
Andrei Catuneanu, Heung-Sik Kim, Oguzhan Can +1
We study possible edge states in single layers of honeycomb materials such as -RuCl and AIrO (A=Li, Na) with strong spin-orbit coupling (SOC). These two dimensional…
Magnetic Orders Proximal to the Kitaev Limit in Frustrated Triangular Systems: Application to BaIrTiO
Andrei Catuneanu, Jeffrey G. Rau, Heung-Sik Kim +1
Frustrated transition metal compounds in which spin-orbit coupling (SOC) and electron correlation work together have attracted much attention recently. In the case of 5 transiti…
Kitaev magnetism in honeycomb RuCl3 with intermediate spin-orbit coupling
Heung-Sik Kim, V. Vijay Shankar, Andrei Catuneanu +1
Intensive studies of the interplay between spin-orbit coupling (SOC) and electronic correlations in transition metal compounds have recently been undertaken. In particular, $j_{\rm…
