Exotic particles, chilled and trapped, form giant matter wave
Exotic particles, chilled and trapped, form giant matter waveR & D MagazinePhysicists have trapped and cooled exotic particles called excitons so effectively that they condensed and cohered to form a giant matter wave. This feat will allow scientists to better study the physical properties of excitons, which exist only ...and more »
Particle physics: A reminder of the beauty we know
Particle physics: A reminder of the beauty we knowNature.comThe latest measurements of the mass of the W boson, one of two elementary particles that mediate the weak nuclear force, are a powerful reminder of the profound beauty in the standard model of particle physics. The most precise measurement so far of ...
Photonics: Beam me up
Photonics: Beam me upPhys.OrgUsually, if a laser beam hits a small particle in its path, the light is scattered backwards, which in turn pushes the particle forward. What Wang and co-workers have now shown theoretically for Bessel beams is that for particles that are sufficiently ...and more »

Disentangling the wave-particle duality in the double-slit experiment
Disentangling the wave-particle duality in the double-slit experimentArs TechnicaPhotons act like they go through two paths, even when we know which they took. by Matthew Francis - May 21, 2012 10:00 pm UTC The subtlest experiment in quantum mechanics is also one of the simplest: send a stream of particles through two openings in a ...
