Exact Organization of Density Matrices and Entanglement Structure in the Kitaev Spin Liquid
Chen-Chih Wang, Yi-Ping Huang, Sungkit Yip
We give an exact form of the density matrix of the spin-1/2 Kitaev spin liquid represented in terms of spin operators and study the entanglement structures of the Kitaev honeycomb…
The gauge theory dual of the bilayer XY model with second order Josephson coupling
Pye Ton How, Sungkit Yip
We formulate a duality transformation for a bilayer XY model where the layers are coupled by second order Josephson effect, which favors inter-layer phase difference of either …
Quantum Spin Liquid phases in Kitaev Materials
Po-Hao Chou, Chung-Yu Mou, Chung-Hou Chung +1
We develop a gauge-invariant renormalized mean-field theory (RMFT) to reliably find the quantum spin liquid (QSL) states and their field response for realistic Kitaev materials und…
Broken time reversal symmetry vestigial state for a two-component superconductor in two spatial dimensions
P. T. How, S. K. Yip
We consider the vestigial phase with broken time-reversal symmetry above the superconducting transition temperature of a two-component superconductor in two spatial dimensions. We…
