Physicists have learned how to control the nucleus of an atom using an electric field

The researchers conducted experiments on various manifestations of nuclear magnetic resonance, which

arises in substances with nuclei with a nonzero magnetic moment. This means that the electric charge in them "rotates" relative to their core.

Under the influence of an external magnetic field, the magnetic moments of its nuclei reorient, and the substance will resonantly absorb or radiate electromagnetic energy at a certain frequency.

This technology is used in many modern devices - with its help you can analyze the rock or analyze the state of organs and tissues in the human body.

In the course of the new work, the researchers conducted a series of experiments with nuclear magnetic resonance using an example of one antimony atom, an element whose nucleus has a sufficiently large intrinsic magnetic moment.

At the very beginning of the experiment, an antenna thathad to create a magnetic field and control the rotation of the atom, exploded. However, even after the antenna failed, scientists recorded resonant radiation.

“It turns out that after damage the antennainstead of a magnetic start, generate a strong electric field. Thus, we “rediscovered” nuclear electric resonance. Our discovery means that now scientists have the opportunity to create quantum computers based on single atoms, without the application of any magnetic field. "

Previously, physicists called ice the ideal fuel for a fusion reactor.
