报告摘要:

In two dimensions, topologically ordered phases defined on a nontrivial manifold have degenerate ground states protected by a gap. It is thus an important topic to find realistic Hamiltonians which support such exotic phases. The DMRG method is one of the most powerful numerical methods for studying strongly correlated quantum many-body systems. However, for topologically ordered systems, it has been a nontrivial task to obtain the complete set of degenerate ground states in DMRG. In this talk I will discuss our recent progress on using the anyon eigenbasis (also known as “minimally entangled states”) as the initialization ansatz in DMRG to obtain the complete set of degenerate ground states and characterize their topological order.
