Seeing an elusive magnetic effect through the lens of machine learning

Superconductors have long been considered the principal approach for realizing electronics without resistivity. In the past decade, a new family of quantum materials, “topological materials,” has offered an alternative but promising means for achieving electronics without energy dissipation (or loss). Compared to superconductors, topological materials provide a few advantages, such as robustness against disturbances. To […]

Physicists steer chemical reactions by magnetic fields and quantum interference

Physicists in the MIT-Harvard Center for Ultracold Atoms (CUA) have developed a new approach to control the outcome of chemical reactions. This is traditionally done using temperature and chemical catalysts, or more recently with external fields (electric or magnetic fields, or laser beams). MIT CUA physicists have now added a new twist to this: They […]

Physicists discover “secret sauce” behind exotic properties of a new quantum material

MIT physicists and colleagues have discovered the “secret sauce” behind some of the exotic properties of a new quantum material that has transfixed physicists due to those properties, which include superconductivity. Although theorists had predicted the reason for the unusual properties of the material, known as a kagome metal, this is the first time that […]

Physicists watch as ultracold atoms form a crystal of quantum tornadoes

The world we experience is governed by classical physics. How we move, where we are, and how fast we’re going are all determined by the classical assumption that we can only exist in one place at any one moment in time. But in the quantum world, the behavior of individual atoms is governed by the […]
