At A Glance

Researchers at Colorado State University in collaboration with Bryn Mawr College have developed a novel method to encrypt and recover non-volatile data exploiting quasiparticles.  Quasiparticles have gained much attention in recent research due to their theoretical minimization of data storage, logic devices, and processing electronics.

In physics, quasiparticles and collective excitations (which are closely related) are emergent phenomena that occur when a microscopically complicated system such as a solid behaves as if it contained different weakly interacting particles in vacuum. Generally speaking, solids are made of only three kinds of particles: electrons, protons, and neutrons. Quasiparticles are none of these; instead, each of them is an emergent phenomenon that occurs inside the solid. Therefore, while it is quite possible to have a single particle (electron or proton or neutron) floating in space, a quasiparticle can only exist inside interacting many-particle systems (primarily solids). One particular form of quasiparticle are skyrmions, having small size and low energy consumption – making them good candidates for data-storage solutions and other computing devices.
