Symmetry breaking in zero-field two-dimensional electron bilayers
Tessa Cookmeyer, Sankar Das Sarma
We theoretically consider bilayers of two dimensional (2D) electron gases as in semiconductor quantum wells, and investigate possible spontaneous symmetry breaking transitions at l…
Engineering the Kitaev spin liquid in a quantum dot system
Tessa Cookmeyer, Sankar Das Sarma
The Kitaev model on a honeycomb lattice may provide a robust topological quantum memory platform, but finding a material that realizes the unique spin liquid phase remains a consid…
Four-Spin Terms and the Origin of the Chiral Spin Liquid in Mott Insulators on the Triangular Lattice
Tessa Cookmeyer, Johannes Motruk, Joel E. Moore
At strong repulsion, the triangular-lattice Hubbard model is described by spins with nearest-neighbor antiferromagnetic Heisenberg interactions and exhibits conventional 12…
Half-magnetization plateau and the origin of threefold symmetry breaking in an electrically-switchable triangular antiferromagnet
Shannon C. Haley, Eran Maniv, Tessa Cookmeyer +8
We perform high-field magnetization measurements on the triangular lattice antiferromagnet FeNbS. We observe a plateau in the magnetization centered at approximately ha…
