New electronic state of matter

A research team led by professors from the University of Pittsburgh, Department of Physics and Astronomy, has announced the discovery of a new electronic state of matter.

The research focused on measurements in one-dimensional conducting systems where electrons are found to travel without scattering in groups of two or more at a time, rather than individually.

The discovery shows that when electrons can be made to attract one another, they can form bunches of two, three, four and five electrons that literally behave like new types of particles, new forms of electronic matter, like quarks binding together to form neutrons and protons.

The ballistic conductors matched a sequence within Pascal’s Triangle.

The new particles feature properties relates to quantum entanglement, which can potentially be used for quantum computing and quantum redistribution.

The study was published in Science. (
