Quantum Phenomenon Shown with Plastic Film

Facebook X LinkedIn Email
Instead of the usual ultrapure crystals, a plastic film similar to the material used in light-emitting smartphone displays has been used to demonstrate a complex quantum mechanical phenomenon. The first-time demonstration of a Bose-Einstein condensation (BEC) at room temperature using a luminescent polymer, achieved by scientists at IBM Research, has potential applications in the development of novel optoelectronic devices, such as energy-efficent lasers and ultrafast optical switches. Such components are critical for powering the future computer systems needed to process massive Big...Read full article

    bose-einstein condensate
    A Bose-Einstein condensate (BEC) is a state of matter that forms at temperatures close to absolute zero. It is named after Satyendra Nath Bose and Albert Einstein, who independently predicted the existence of such a state in the 1920s. BEC is a unique and fascinating form of matter that exhibits macroscopic quantum phenomena. In a Bose-Einstein condensate, some key factors to consider are: Temperature: BEC forms at extremely low temperatures, typically in the nanokelvin (billionths of a...
    optoelectronic
    Pertaining to a device that responds to optical power, emits or modifies optical radiation, or utilizes optical radiation for its internal operation. Any device that functions as an electrical-to-optical or optical-to-electrical transducer. Electro-optic often is used erroneously as a synonym.
    polariton
    A polariton is a quasiparticle resulting from the strong coupling between photons (light particles) and certain types of excitations in a material, such as electronic excitations (electrons and holes) or vibrational excitations (phonons). The interaction between light and matter in a medium gives rise to a new hybrid state known as a polariton, which exhibits properties that are distinct from those of the individual photons and excitations. There are different types of polaritons based on the...
