The first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

This review elaborates pedagogically on the fundamental concept, basic theory, expected
properties, and materials realizations of topological superconductors. The relation between …

Topological superconductors are novel classes of quantum condensed phases,
characterized by topologically nontrivial structures of Cooper pairing states. On the surfaces …

Topological insulator (TI), a promising quantum and semiconductor material, has gapless
surface state and narrow bulk band gap. Firstly, the properties, classifications and …

Superconductivity in topological materials has drawn significant interest from the scientific
community as these materials provide a hint of the existence of Majorana fermions …

Abstract 2D SnTe films with a thickness of as little as 2 atomic layers (ALs) have recently
been shown to be ferroelectric with in‐plane polarization. Remarkably, they exhibit transition …

Strontium intercalation between van der Waals bonded layers of the topological insulator Bi
2 Se 3 is found to induce superconductivity with a maximum T c of 2.9 K. Transport …

Since the discovery of graphene, 2D materials have attracted significant attention for their
unique properties. Monoelemental 2D materials (ME2DMs) are of particular interest …

High-dimensional quantum key distribution (HDQKD) offers the possibility of high secure-
key rate with high photon-information efficiency. We consider HDQKD based on the time …

In this paper we introduce a solvable two-orbital (two-band) model with an infinite-range
Hatsugai-Kohmoto interaction, which serves as a modified periodic Anderson model. Its …
