Direct THz Plasmon Imaging Reveals 2D Superconducting Superfluid

Researchers used near-field terahertz spectroscopy with a spintronic THz emitter to image a below-gap, two-dimensional superfluid plasmon in few-layer Bi2Sr2CaCu2O8+x. The resonance, observed only in the superconducting phase and absent in bulk samples, was mapped for its dispersion and geometric anisotropy, providing a direct, spatially resolved view of momentum- and frequency-dependent 2D superconductivity and the superfluid stiffness within the CuO2 planes.

Scientists Discover a Massless Demon Particle

Scientists at the University of Illinois have discovered evidence of a massless, neutral plasmon called a 'demon' in the metal strontium ruthenate, supporting a 1956 theory and potentially advancing understanding of high-temperature superconductors by revealing a new quasiparticle that could operate at room temperature.

Unveiling the Enigmatic 'Demon Particle': A Breakthrough in Scientific Understanding

Scientists have discovered a particle known as the "Demon Particle" that could revolutionize our understanding of superconductors and potentially lead to the development of room-temperature superconductors. Superconductors are materials that have zero electrical resistance, but they currently require extreme cooling to achieve this state. The Demon Particle, a massless plasmon, could help electrons flow through materials effortlessly, allowing electricity to flow indefinitely without resistance. The discovery of this particle provides valuable insight into the behavior of superconductors and brings us closer to the possibility of practical applications in energy generation.
