Chiral spin liquid in a frustrated anisotropic kagome Heisenberg model
Yin-Chen He, D. N. Sheng, Yan Chen
Kalmeyer-Laughlin (KL) chiral spin liquid (CSL) is a type of quantum spin liquid without time-reversal symmetry, and it is considered as the parent state of an exotic type of super…
Obtaining topological degenerate ground states by the density matrix renormalization group
Yin-Chen He, D. N. Sheng, Yan Chen
We develop the density matrix renormalization group approach to systematically identify the topological order of the quantum spin liquid (QSL) through adiabatically obtaining diffe…
Universal impurity-induced bound state in topological superfluids
Hui Hu, Lei Jiang, Han Pu +2
We predict a universal mid-gap bound state in topological superfluids, induced by either non-magnetic or magnetic impurities in the strong scattering limit. This universal state is…
Topological quantum memory interfacing atomic and superconducting qubits
Zheng-Yuan Xue, Zhang-qi Yin, Yan Chen +2
We propose a scheme to manipulate a topological spin qubit which is realized with cold atoms in a one-dimensional optical lattice. In particular, by introducing a quantum opto-elec…
