报告摘要:Majorana fermions are emergent quasiparticles in condensed matter physics. In topological superconductors, there exist unpaired Majorana zero modes that have the prospect of topological quantum computation. Moreover, Majorana fermions offer new perspective of strongly correlated systems. In this talk, Ill discuss an interacting Majorana fermion model on square lattice. The ground state is obtained exactly and exhibits the nontrivial coexistence of spontaneous symmetry breaking and topological order. The Z2 symmetry breaking leads to the intertwined spin and pairing orders. The topological order is reflected in the Z2 quantum spin liquid state. Such Majorana fermion perspective can be adopted to explore other strongly correlated systems.
