Current technology using polycrystalline electrical steels operates at a maximum magnetic induction of 1.6 T. Here it is proposed to change this to greater than 2 T using patterned polycrystalline iron with energy savings approaching a trillion dollars per year. Such a fundamental change in technology may take a generation.

Recently synthesized, tin iodide phosphorus (SnIP) is the first of a new class of materials with carbon-less double-helix structure [1]. Unlike DNA, which consists of two equal-radius helices, the SnIP double helix consists of an outer SnI chain with 0.98 nm diameter wrapping around an inner P chain. Bulk SnIP consists of bundles of needles weakly bound through Van-Der Waals forces to form...

Ionized chalcogen donors in silicon, such as S+, Se+, and Te+, offer excellent spin qubit properties on par with the commonly studied group V hydrogenic “shallow” donors such as phosphorus. These deep chalcogen donors have the additional advantage of spin-selective, mid-infrared optical access to their lowest excited valley-orbit states. By coupling this optical transition to silicon photonic...

A multitude of radiation damage centers in Si with highly reproducible optical emission and absorption lines have been studied exhaustively using a wide variety of techniques over the past 50+ years. Some of these centers produce very bright luminescence, and have recently received renewed interest as possible light emitters, and single photon sources, compatible with an integrated silicon...

Spreading processes on networks are ubiquitous, including neuronal avalanches, human and computer viruses, and information spreading on social networks. Spreading processes exemplify a nonequilibrium phase transition into an absorbing state; the transition to the absorbing state will certainly occur when the mean branching ratio falls below one. These processes are typically studied assuming...

Most multiferroic materials with coexisting ferroelectric and magnetic order exhibit cycloidal antiferromagnetism with wavelength much larger than lattice spacing. The prototypical example is bismuth ferrite (BiFeO$_3$ or BFO), a room-temperature multiferroic considered for a number of technological applications, including magnetic memories with electric-write capability. While most...
