Physicists Discover 'Demon' Particle Inside Superconductor, Could Explain How They Work
In a breakthrough that could revolutionize our understanding of superconductivity, physicists have discovered a mysterious "demon" particle inside a superconductor. The particle, called a Pines' demon , is a transparent, chargeless quasiparticle that could shed more light on the underlying mechanics of superconductivity . Pines' demons were first predicted by Nobel Prize-winning physicist David Pines in the 1950s. They are thought to be created when electrons in a superconductor form a collective state. This state allows the electrons to move through the material without any resistance. The researchers who discovered Pines' demons used a technique called angle-resolved photoemission spectroscopy to study a superconductor called strontium ruthenate. They found that the spectrum of the electrons in the superconductor showed a clear signature of Pines' demons . It consists of electrons in different energy bands moving out of phase with each other, such that...
