Gravedad de la NASA Probe B (GP-B) La misión ha confirmado dos predicciones fundamentales derivadas de la teoría general de Albert Einstein de la relatividad, que fue diseñado para probar la nave. El experimento, iniciado en 2004, utilizó cuatro giroscopios ultra-precisos para medir el efecto de la hipótesis de geodésica, la curvatura del espacio y [...]

Physicists at UC San Diego have created a successful rapid integration of circuits particles called “excitons” commercially operating in cold temperatures, so the possibility of a new type of extremely fast computer based on excitons closer to reality. Their discovery, detailed this week in the advance online edition of the journal Nature Photonics, following the [...]

A team of researchers at the University of Zaragoza (UNIZAR, Spain) and the Institut d’Astrophysique Spatiale (IAS, France) has developed a brilliant bolometer, a device that scientists use in efforts to detect dark matter of the universe, and has been tested in the Underground Laboratory Canfranc in Huesca, Spain. “One of the biggest challenges in [...]

Like a giant wave in a sea of gaseous calcium atoms, the Bose-Einstein condensate rises. It consists of approx. 20 000 atoms that are not normally visible to the human eye. However, the waves describing the quantum mechanics of atoms, all oscillate synchronously in the condensate and accumulate to form a dense tidal wave. Thus, [...]

A nitrogen vacancy (small circles) within a diamond crystal is promising as a little ‘for quantum computers, in part due to its high sensitivity to magnetic fields, a sensibility that could also allow the RM-like studies objects as small as individual molecules or living cells. When the green light hits the nitrogen vacancy, which emits [...]
