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 …

Emergence of exceptional points in two dimensions is one of the remarkable phenomena in
non-Hermitian systems. We here elucidate the impacts of symmetry on the non-Hermitian …

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 …

In non-interacting systems, bands from non-trivial topology emerge strictly at half-filling and
exhibit either the quantum anomalous Hall or spin Hall effects. Here we show using …

The long fascination that antiferromagnetic materials has exerted on the scientific community
over about a century has been entirely renewed recently with the discovery of several …

We propose a new correlated topological state, which we call a higher-order topological
Mott insulator (HOTMI). This state exhibits a striking bulk-boundary correspondence due to …

We analyze a diamond-lattice Hubbard model with the spatially modulated Hubbard
interaction. Our dynamical mean-field analysis with special emphasis on non-Hermitian …

Spin-orbit (SO) coupling is the crucial parameter to drive topological-insulating phases in
electronic band models. In particular, the generic emergence of SO coupling involves the …

We investigate the correlation-induced Mott, magnetic, and topological phase transitions in
artificial (111) bilayers of perovskite transition-metal oxides La Au O 3 and Sr Ir O 3 for which …
