About the difficulty of imprisoning a glass ball in several dimensions

Extreme cold is no easy matter. Many quantum properties that are interesting for research only become apparent at temperatures close to absolute zero, but we live in a very warm world that quickly warms up any cold object if it is not hermetically shielded and thermal energy is not extracted from it using various tricks. Nevertheless, it has already been possible in laboratories to cool down tiny glass beads extremely and to immobilize them in one direction of movement. So far, however, there has been some movement in the other two directions. A Swiss team with Innsbruck participation has now managed to “freeze” in two dimensions for the first time and reported on it in the journal “Nature Physics”.
