Distinct Spin Liquids and their Transitions in Spin-1/2 XXZ Kagome Antiferromagnets
Yin-Chen He, Yan Chen
By using the density matrix renormalization group, we study the spin-liquid phases of spin- XXZ kagome antiferromagnets. We find that the emergence of spin liquid phase does n…
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…
Measuring Majorana fermions qubit state and non-Abelian braiding statistics in quenched inhomogeneous spin ladders
Yin-Chen He, Yan Chen
We study the Majorana fermions (MFs) in a spin ladder model. We propose and numerically show that the MFs qubit state can be read out by measuring the fusion excitation in the quen…
