Macroscopic spin moves
James Kikkawa and David Awschalom of the University of California, Santa Barbara have now shown that they can use electric fields to transport electrons through a distance of 0.1 mm in gallium arsenid...
The force of acoustics
“The idea of using white noise to mimic zero-point fluctuations is clever, ” said Steve Lamoreaux of Los Alamos National Laboratory in the US. “The fundamentals are quite different f...
Microlasers get even smaller
Attempts to scale down current laser designs have been made before, but the devices were not efficient enough for real applications. Now a group of researchers from Darmstadt University of Technology,...
Quantum teleportation goes beyond two states
In quantum teleportation the quantum state of an object held by “Alice” is instantaneously sent to “Bob”. The technique works by sending one half of an “entangled” ...
Wireless quantum encryption
The technique is based on characteristics of individual photons that are generated randomly between the sender and the receiver. Although researchers have already transmitted quantum encryption keys t...
Field theorists win Dirac prize
The citation highlights Adler’s derivation of a sum rule for pion-nucleon scattering that marked a breakthrough in our understanding of the currents and broken symmetries of the strong interacti...
Talking physics with the Dalai Lama
Zeilinger had invited the Dalai Lama to his laboratory following a meeting at Dharamsala in Northern India last October at which he and four other physicists had, over the course of five days, discuss...
Light makes insulator conduct
The researchers cooled the manganese oxide compound (Pr0.7Ca0.3MnO3) to below 200 K in a zero magnetic field. At this temperature the electrons drop into a low energy state, which minimizes their natu...
Shuttle goes on ‘antimatter’ hunt
The known universe consists almost entirely of matter. However, it is thought that equal amounts of matter and antimatter were created during the big bang. One possibility is that this antimatter now ...
