Extraordinary things happen at low temperatures. One of the best examples is superconductivity, a phenomenon wherein the electrical resistance of a solid drops to zero below a critical temperature. Known for a century, superconductivity ...
Scientists at Amherst College and Aalto University have created, for the first time a three-dimensional skyrmion in a quantum gas. The skyrmion was predicted theoretically over 40 years ago, but only now has it been observed ...
University of Groningen physicists have managed to alter the flow of spin waves through a magnet, using only an electrical current. This is a huge step towards the spin transistor that is needed to construct spintronic devices. ...
Our world consists mainly of particles built up of three quarks bound by gluons. The process of the sticking together of quarks, called hadronisation, is still poorly understood. Physicists from the Institute of Nuclear Physics ...
What is inside an atom between the nucleus and the electron? Usually there is nothing, but why could there not be other particles too? If the electron orbits the nucleus at a great distance, there is plenty of space in between ...
The common link between liquid-crystal TVs and the birth of the universe, when you look at the big picture, is that they are both characterized by the intriguing phenomenon in which matter abruptly changes states.
ICFO researchers created a novel type of liquid 100 million times more dilute than water and 1 million times thinner than air. The experiments, published in Science, exploit a fascinating quantum effect to produce droplets ...
Excitons are pairs of electrons and holes inside a solid material that together behave like a single particle. It has long been suspected that when many such excitons exist in the same piece of matter, they can form a single ...
Ever since its invention, the laser has been an invaluable tool in physics. It is expected that an atom laser - with the light waves replaced by the quantum waves of atoms - could have similarly important applications, for ...
The world of an atom is one of random chaos and heat. At room temperatures, a cloud of atoms is a frenzied mess, with atoms zipping past each other and colliding, constantly changing their direction and speed.
