Topological materials have become the focus of intense research in recent years, since they
exhibit fundamentally new physical phenomena with potential applications for novel devices …

Topological materials discovery has evolved at a rapid pace over the past 15 years following
the identification of the first nonmagnetic topological insulators (TIs), topological crystalline …

The search for new two-dimensional monolayers with diverse electronic properties has
attracted growing interest in recent years. Here, we present an approach to construct MA2Z4 …

Using density functional theory and Monte Carlo calculations, we study the thickness
dependence of the magnetic and electronic properties of a van der Waals interlayer …

We present an open-source software package WannierTools, a tool for investigation of novel
topological materials. This code works in the tight-binding framework, which can be …

We study fourfold rotation-invariant gapped topological systems with time-reversal symmetry
in two and three dimensions (d= 2, 3). We show that in both cases nontrivial topology is …

We show that the electronic structure of the low-energy bands in the small angle-twisted
bilayer graphene consists of a series of semimetallic and topological phases. In particular …

Abstract Two-dimensional (2D) materials have emerged as promising candidates for next-
generation electronic and optoelectronic applications. Yet, only a few dozen 2D materials …

A non-Hermitian system can exhibit extensive sensitivity of its complex energy spectrum to
the imposed boundary conditions, which is beyond any known phenomenon from Hermitian …

Fermions—elementary particles such as electrons—are classified as Dirac, Majorana or
Weyl. Majorana and Weyl fermions had not been observed experimentally until the recent …
