Anyone for Anyons?

Researchers have demonstrated that a strange type of quantum particle called the anyon, believed to exist in only two dimensions, can also be created in one dimension. Further studies exploring different types of one-dimensional anyons could bring scientists one step closer to using the particles as a fundamental unit of memory in a quantum computer. A team led by Harvard scientists Joyce Kwan and

A current (white arrow) flowing through a tantalum film generates a current of spins (dark blue arrows) that impinges on the ferromagnetic cobalt iron boron layer and causes the magnetization (gold arrow) to charge directions (light blue arrow).

Theory of Spin-Orbit Torque

Completed

A ferromagnetic material such as iron acquires its magnetization because the magnetic orientation of its constituent atoms all line up in the same way. Because individual electrons also have an intrinsic magnetic moment – which is often referred to as the electron “spin” - they can interact with

Magnetic Imaging

Completed

Advanced magnetic devices and storage media will rely on ultra thin ferromagnetic films; since such films are quasi two-dimensional magnets, they can have strong perpendicular magnetic anisotropy (PMA). Optimization of future materials, including improved yields, requires an ability to measure film

Advanced Magnetic Imaging

Ongoing

Ultra-low field (ULF) MRI MRI systems are widely used for clinical diagnostics where imaging is typically done in high-field magnets ranging from 1.5 T to 7 T to achieve a manageable signal-to-noise ratio needed for short imaging times (few minutes) and high resolution (1 mm or less). Ultra-low
