Nematic chiral spin liquid in a Kitaev magnet under external magnetic field
Shun-Yao Yu, Han Li, Qi-Rong Zhao +5
The possible existence of a quantum spin liquid (QSL) phase, an exotic state of matter with long-range quantum entanglement and fractionalized excitations, in -RuCl has spar…
Measurable signatures of bosonic fractional Chern insulator states and their fractional excitations in a quantum-gas microscope
Botao Wang, Xiao-Yu Dong, André Eckardt
The recent progress in engineering topological band structures in optical-lattice systems makes it promising to study fractional Chern insulator states in these systems. Here we co…
