Have you noticed something strange in your WiFi connection? If you apparently have no problems with your network and you find that, your connection is going too slow. It may be happening. Someone may be stealing your WiFi. One of the clearest signs, when it comes to knowing if someone ...Optical connection of several remote nanooptomechanical systems
For the first time, physicists have coupled remote optomechanical nano-oscillators via an optical wave guide. This coupling allowed them to observe the locking of the oscillators on a common frequency of oscillation. These results are published in the journal Physical Review Letters. The light injected into an opto-mechanical resonator can ...
