Richard Feynman on Quantum Mechanics - Part 1 - Photons: Corpusc. MIT physicist to describe strange world of quarks, gluons. One of the great theoretical challenges facing physicists is understanding how the tiniest elementary particles give rise to most of the mass in the visible universe. Tiny particles called quarks and gluons are the building blocks for larger particles such as protons and neutrons, which in turn form atoms. However, quarks and gluons behave very differently than those larger particles, making them more difficult to study.

John Negele, the W.A. Coolidge Professor of Physics at MIT, will talk about the theory that governs interactions of quarks and gluons, known as quantum chromodynamics (QCD), during a Feb. 17 presentation to the American Association for the Advancement of Science annual meeting in Boston. Negele will describe how scientists are using supercomputers and a concept called lattice field theory to figure out the behavior of quarks and gluons, the smallest known particles. Molecules are built from atoms, atoms from electrons and nuclei, and nuclei from protons and neutrons. Physicist proposes method to teleport energy. (PhysOrg.com) -- Using the same quantum principles that enable the teleportation of information, a new proposal shows how it may be possible to teleport energy. By exploiting the quantum energy fluctuations in entangled particles, physicists may be able to inject energy in one particle, and extract it in another particle located light-years away.

The proposal could lead to new developments in energy distribution, as well as a better understanding of the relationship between quantum information and quantum energy. Japanese physicist Masahiro Hotta of Tohoku University has explained the energy teleportation scheme in a recent study posted at arxiv.org, called “Energy-Entanglement Relation for Quantum Energy Teleportation.” Previously, physicists have demonstrated how to teleport the quantum states of several different entities, including photons, atoms, and ions. In quantum energy teleportation, a physicist first makes a measurement on each of two entangled particles.
