Ways to save the planet: Activating the states

With global temperatures rising and the clock ticking, Fletcher School experts the world over are developing new ways to save the planet. For a series on climate change solutions, Tufts Now talked with several Fletcher alumni ...

Probing a nuclear clock transition

Modern atomic clocks are the most accurate measurement tools currently available. The best current instruments deviate by just one second in 30 billion years. However, even this extraordinary level of precision can be improved ...

Laser-produced uranium plasma evolves into more complex species

When energy is added to uranium under pressure, it creates a shock wave, and even a tiny sample will be vaporized like a small explosion. By using smaller, controlled explosions, physicists can test on a microscale in a safe ...

Detraction-free light-matter interaction

An efficient light-matter interface might constitute the foundation of quantum communication. However, certain structures that are formed during the growth process interfere with the signal.

Physicists create world's smallest engine

Theoretical physicists at Trinity College Dublin are among an international collaboration that has built the world's smallest engine—which, as a single calcium ion, is approximately ten billion times smaller than a car ...
