Near ground-state cooling of 2-D trapped ion crystals

Researchers have been trying to cool macroscopic mechanical oscillators down to their ground state for several decades. Nonetheless, past studies have merely attained the cooling of a few selected vibrational modes of such ...

Do alpha particle condensates exist in oxygen nuclei?

Nuclei in their lowest energy states (ground state) are composed of neutrons and protons. Two protons and two neutrons in a nucleus can cluster together to form alpha particles. When the nucleus gets nearly enough energy ...

Why does nuclear fission produce pear-shaped nuclei?

Nuclear fission is a process in which a heavy nucleus split into two. Most of the actinides nuclei (plutonium, uranium, curium, etc) fission asymmetrically with one big fragment and one small. Empirically, the heavy fragment ...

Physicists control transitions between different states of matter

An international group of physicists managed for the first time to experimentally observe the transition between two states of matter, propagating polariton-solitons and a Bose-Einstein condensate. Furthermore, physicists ...

Light controls two-atom quantum computation

Some powerful rulers of the world may dream of the possibility to get in touch with their colleagues on different continents unnoticed by friends or foes. Someday, new quantum technologies could allow for making these wishes ...
