A kagome lattice naturally features Dirac fermions, flat bands and van Hove singularities in
its electronic structure. The Dirac fermions encode topology, flat bands favour correlated …

Spintronics and quantum information science are two promising candidates for innovating
information processing technologies. The combination of these two fields enables us to build …

Chern insulators, which are the lattice analogues of the quantum Hall states, can potentially
manifest high-temperature topological orders at zero magnetic field to enable next …

The interplay between spontaneous symmetry breaking and topology can result in exotic
quantum states of matter. A celebrated example is the quantum anomalous Hall (QAH) state …

The fractional quantum anomalous Hall effect (FQAHE), the analogue of the fractional
quantum Hall effect at zero magnetic field, is predicted to exist in topological flat bands …

The quantum Hall (QH) effect, quantized Hall resistance combined with zero longitudinal
resistance, is the characteristic experimental fingerprint of Chern insulators—topologically …

Majorana bound states constitute one of the simplest examples of emergent non-Abelian
excitations in condensed matter physics. A toy model proposed by Kitaev shows that such …

A recent experiment has reported the first observation of a zero-field fractional Chern
insulator (FCI) phase in twisted bilayer MoTe 2 moiré superlattices [J. Cai, Signatures of …

Quantum spin liquids, exotic phases of matter with topological order, have been a major
focus in physics for the past several decades. Such phases feature long-range quantum …

BACKGROUND The past two decades have seen intense efforts aimed at building quantum
