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 …

Inversion and time reversal are essential symmetries for the structure of Cooper pairs in
superconductors. The loss of one or both leads to modifications to this structure and can …

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 …

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 …

The discovery of the multiple HT phase diagram of CeRh 2 As 2 offers a new route to
designing topological superconductors. Although weak-coupling theories explain the …

Despite recent extensive studies of the non-Hermitian topology, understanding interaction
effects is left as a crucial question. In this paper, we address interaction effects on …

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

Quasi-particles described by Green's functions of equilibrium systems exhibit non-Hermitian
topological phenomena because of their finite lifetime. This non-Hermitian perspective on …

In spite of extensive works on non-Hermitian topology, interaction effects remain crucial
questions. We analyze correlated non-Hermitian systems with special emphasis on the one …

Spin-orbit coupling in transition metal dichalcogenides (TMDCs) causes spin-valley locking,
giving rise to unconventional optical, transport, and superconducting properties. In this …
