Physicists propel macroscopic diamond sample using internal electron spin forces

Physicists have successfully moved a macroscopic sample of diamond using only the force generated by its own internal electron spins. Physics World reported that the experimental breakthrough shows how tiny quantum mechanical effects can accumulate to produce a measurable classical physical movement. [1]

The research team was led by physicist Jason Twamley at the Okinawa Institute of Science and Technology in Japan. According to Physics World, the scientists manipulated nitrogen-vacancy centres inside the diamond structure to propel the macroscopic sample by distances of up to 1.5 microns. [1]

Electrons are fundamental subatomic particles with negative charge that occupy discrete energy levels around an atomic nucleus, as established when J.J. Thomson discovered them in 1897. In solid materials, the absence of an electron creates an electron hole, which acts as a quasiparticle with a net positive charge within the atomic lattice. [2][3]

Twamley stated that the spin force can act as a quantum force capable of displacing macroscopic objects despite the small scale of individual spins. Physics World reported that this mechanism could enable a new class of ultra-precise sensors designed to test the boundaries of quantum mechanics and probe gravitational forces. [1]
