1930 – Cooper – bio

Leon Cooper was born in 1930 in New York, USA. He is most known for discovering how electrons pair together, creating a state of less resistance, known as superconductivity. These are now called, “Cooper pairs”. Bardeen, Cooper, and Schrieffer, built on this concept to create a theory of superconductivity in 1957. The three of them […]

Using Sound to Control Information

Computer circuits use pulses of electromagnetic energy to create readable states that can represent information in small pieces. Phonons are pulses of sound vibration that can interact with both matter and electromagnetic energy. Learning to control phonons with precision may enable phonon based computing. How To Build A Phononic Computer [technologyreview.com] Phonons are quantum vibrations […]

Liquid Crystal Phonon Lenses

Liquid crystals are substances that have some form of crystalline structure and exhibit some characteristics of crystals but flow like a liquid. They form long thin molecules that have either some electromagnetic component or an optical component such as light polarization. Liquid Crystal Displays (LCD) use these electrical and optical qualities of liquid crystals to […]
