Stacking of charge-density waves in 2H-NbSe bilayers
Fabrizio Cossu, Dhani Nafday, Krisztian Palotás +4
We employ ab-initio electronic structure calculations to investigate the charge-density waves and periodic lattice distortions in bilayer 2H-NbSe. We demonstrate that the verti…
Suppression of Antiferromagnetic Order by Strain in Honeycomb Cobaltate: Implication for Quantum Spin Liquid
Gye-Hyeon Kim, Miju Park, Uksam Choi +8
Recently, layered honeycomb cobaltates have been predicted as a new promising system for realizing the Kitaev quantum spin liquid, a many-body quantum entangled ground state charac…
Emergent half-metal with mixed structural order in (111)-oriented (LaMnO)|(SrMnO) superlattices
Fabrizio Cossu, Jùlio Alves Do Nascimento, Stuart A. Cavill +3
Using first-principles techniques, we study the structural, magnetic and electronic properties of (111)-oriented (LaMnO)(SrMnO) superlattices of varying…
Optical detection of bond-dependent and frustrated spin in the two-dimensional cobalt-based honeycomb antiferromagnet Cu3Co2SbO6
Baekjune Kang, Uksam Choi, Taek Sun Jung +18
Two-dimensional honeycomb antiferromagnet becomes an important class of materials as it can provide a route to Kitaev quantum spin liquid, characterized by massive quantum entangle…
