Abstract No barrier MgB2/SS composite wire was fabricated by the powder-in-tube (PIT) and by the internal magnesium diffusion (IMD) into boron process. Mechanically strong SS sheath keeps the high density of boron powder during could wire drawing, which allows the creat...

With infrared spectroscopy, we studied the bulk electronic properties of the topological antiferromagnet $\mathrm{Mn}{\mathrm{Bi}}_{2}{\mathrm{Te}}_{4}$ with ${T}_{N}\ensuremath{\simeq}25\phantom{\rule{4pt}{0ex}}\mathrm{K}$. With the support of band-structure calculatio...

Using nuclear quadrupole resonance, the phase diagram of $1111 R{\mathrm{FeAsO}}_{1\ensuremath{-}x}{\mathrm{F}}_{x}$ ($R=\text{La}$, Ce, Sm) iron pnictides is constructed as a function of the local charge distribution in the paramagnetic state, which features low-doping...

Topologically ordered states of matter are generically characterized by excitations with quantum number fractionalization. A prime example is the spin liquid realized in Kitaev's honeycomb-lattice compass model where spin-flip excitations fractionalize into Majorana fer...

Multiphase flows in porous media are important in many natural and industrial processes. Pore-scale models for multiphase flows have seen rapid development in recent years and are becoming increasingly useful as predictive tools in both academic and industrial applicati...

Atmospheric pressure plasma jet machining technology provides a flexible and efficient way to fabricate precise freeform optics. Due to the pure chemical material removal mechanism based on a dry etching process using fluorine containing gas, the choice of materials tha...

Controlling strain in hetero-epitaxial material systems can be used to optimize properties and functionalities for specific applications. For this purpose, a lattice mismatch between substrate and epitaxial layer is typically exploited. Beyond that, vicinal substrate su...

In underdoped cuprate superconductors, a rich competition occurs between superconductivity and charge density wave (CDW) order. Whether rotational symmetry breaking (nematicity) occurs intrinsically and generically or as a consequence of other orders is under debate. He...

In this study, isovalent chemical substitution is used to tune adiabatically structural and electronic degrees of freedom in a cuprate high-temperature superconductor. The strength of charge density modulations in the electronic states responsible for superconductivity ...

The spin Hall effect (SHE), which converts a charge current into a transverse spin current, has long been believed to be a phenomenon induced by spin–orbit coupling. Here, we identify an alternative mechanism to realize the intrinsic SHE through a noncollinear magnetic ...
