Magnetic skyrmions are particle-like nanometre-sized spin textures of topological origin
found in several magnetic materials, and are characterized by a long lifetime. Skyrmions …

Metamaterials are rationally designed composites aiming at effective material parameters
that go beyond those of the ingredient materials. For example, negative metamaterial …

Magnetism is one of the largest, most fundamental, and technologically most relevant fields
of condensed-matter physics. Traditionally, two basic magnetic phases have been …

Recent series of theoretical and experimental reports have driven attention to time-reversal
symmetry-breaking spintronic and spin-splitting phenomena in materials with collinear …

The anomalous Hall effect is a time-reversal symmetry-breaking magneto-electronic
phenomenon originally discovered in ferromagnets. Recently, ruthenium dioxide (RuO2) …

We present results from the search for a stochastic gravitational-wave background (GWB) as
predicted by the theory of General Relativity using six radio millisecond pulsars from the …

A superconductor is a material that can conduct electricity without resistance below a
superconducting transition temperature, T c. The highest T c that has been achieved to date …

The rapid development of information technology has led to urgent requirements for high
efficiency and ultralow power consumption. In the past few decades, neuromorphic …

Topological insulators are new states of quantum matter which cannot be adiabatically
connected to conventional insulators and semiconductors. They are characterized by a full …

Lifted Kramers spin degeneracy (LKSD) has been among the central topics of condensed-
matter physics since the dawn of the band theory of solids,. It underpins established practical …
