Quantum materials, with nontrivial quantum phenomena and mechanisms, promise efficient
quantum technologies with enhanced functionalities. Quantum technology is held back …

Highlighted with improved long-term thermal and environmental stability, all-inorganic metal
halide perovskites exhibit tunable physical properties, cost-effective synthesis, and …

We review recent studies of the spin-dependent tunneling transport via an Aharonov–Bohm
interferometer (ABI) formed by helical edge states. We focus on the experimentally relevant …

We study coherent spin transport through helical edge states of topological insulator tunnel-
coupled to metallic leads. We demonstrate that unpolarized incoming electron beam …

Edge and bulk energy levels can coexist in a quantum dot (QD) made of a topological
insulator. Interference effect will occur between bulk and edge levels and also between …

The existence of chiral edge states (CES), corresponding to nontrivial bulk‐band topology
characterized by a non‐vanishing topological invariant, and the manipulation of topological …

We theoretically study the spin current and spin-transfer torque (STT) generation in a
conventional spin-valve hybrid structure of type ferromagnetic/normal metal/ferromagnetic …

Spin-polarization control with local magnetic field is one of the fundamental tasks in spin
electronics. In this paper we investigate how to generate the local magnetic field for …
