Quantum phase transition induced by real-space topology
C. Li, G. Zhang, S. Lin +1
A quantum phase transition (QPT), including both topological and symmetry breaking types, is usually induced by the change of global parameters, such as external fields or global c…

Majorana charges, winding numbers and Chern numbers in quantum Ising models
G. Zhang, C. Li, Z. Song
Mapping a many-body state on a loop in parameter space is a simple way to characterize a quantum state. The connections of such a geometrical representation to the concepts of Cher…

Magnetic-flux-driven topological quantum phase transition and manipulation of perfect edge states in graphene tube
S. Lin, G. Zhang, C. Li +1
We study the tight-binding model for a graphene tube with perimeter N threaded by a magnetic field. We show exactly that this model has different nontrivial topological phases as t…
