Peering into the quantum life of electrons in a magnetic field
Princeton University researchers have demonstrated a new way of making controllable "quantum wires" in the presence of a magnetic field, according to a new study. The researchers detected channels of conducting electrons that form between two quantum states on the surface of a bismuth crystal subjected to a high magnetic field. These two states consist of electrons moving in elliptical orbits with different orientations. To the team’s surprise, they found that the current flow in these channels can be turned on and off, making these channels a new type of controllable quantum wire.
