Physicist Hikida from the University of Tokyo and his colleagues developed the dual model for Einstein's theory of gravity in three-dimensional de Sitter space. This is a significant step towards a model that will faithfully describe nature, i.e. the physics of quantum gravity under an expanding universe with a positive cosmological constant.

"In these days," says Prof. Polman, "in which enormous efforts are being invested in all the countries of the world in order to develop quantum technologies, such as the quantum computer, it is extremely important to understand the basic processes that occur when quantum operations are performed on a particle that change its state.

In the study, the scientists examined collisions that occur between the molecules. Collisions of atoms have been studied in the past, but atoms - according to classical physics - are spherical, while molecules have an elongated structure. The structure of a colliding body affects the way it will move after the collision. Will elongated molecules behave differently from spherical atoms? And is knowing their shape enough to predict the outcome of the collision? Illustration: pixabay.com.

Image of light emitted from a single ionized strontium atom immersed in a cold cloud of rubidium atoms. The ion is trapped by electric fields that oscillate at radio frequencies. The atoms are trapped by a focused laser beam. Both the atoms and the ion are cooled to a temperature of a millionth of a Kelvin above absolute zero temperature.
