The discovery of the quantum spin Hall effect and topological insulators more than a decade
ago has revolutionized modern condensed matter physics. Today, the field of topological …

Topological insulators have become one of the most active research areas in condensed
matter physics. This article reviews progress on the topic of electronic correlation effects in …

We show that moiré bands of twisted homobilayers can be topologically nontrivial, and
illustrate the tendency by studying valence band states in±K valleys of twisted bilayer …

We analyze a two-dimensional Kondo lattice model with special emphasis on non-Hermitian
properties of the single-particle spectrum, following a recent proposal by Kozii and Fu. Our …

Twisted bilayer MoTe 2 is a promising platform to investigate the interplay between band
topology and many-body interactions. We present a theoretical study of its interaction-driven …

Presenting the physics of the most challenging problems in condensed matter using the
conceptual framework of quantum field theory, this book is of great interest to physicists in …

In numerical simulations, spontaneously broken symmetry is often detected by computing
two-point correlation functions of the appropriate local order parameter. This approach …

Exotic quantum phases and phase transition in the strongly interacting Dirac systems have
attracted tremendous interests. On the other hand, non-Hermitian physics, usually …

We numerically investigate the critical behavior of the Hubbard model on the honeycomb
and the π-flux lattice, which exhibits a direct transition from a Dirac semimetal to an …

We prove that the Kane-Mele-Hubbard model with purely imaginary next-nearest-neighbor
hoppings has a particle-hole symmetry at half filling. Such a symmetry has interesting …
