Mastering metastable matter

The phenomenon of metastability, in which a system is in a state that is stable but not the one of least energy, is widely observed in nature and technology. Yet, many aspects underlying the mechanisms governing the behaviour ...

Modelling rare events in complex systems

NUS mathematicians have developed efficient methods to study complex energy landscapes and thermally activated events. Many problems arising from applied sciences can be abstractly formulated as a system navigating over a ...

Materials that emit rainbows

Mechanochromic luminescent (MCL) materials change their color in response to a change in their environment, like pressure and temperature. To date, most MCL materials only change between two colors, limiting their applications. ...

Melting solid below the freezing point

Phase transitions surround us—for instance, liquid water changes to ice when frozen and to steam when boiled. Now, researchers at the Carnegie Institution for Science have discovered a new phenomenon of so-called metastability ...

Annihilating nanoscale defects

Target dates are critical when the semiconductor industry adds small, enhanced features to our favorite devices by integrating advanced materials onto the surfaces of computer chips. Missing a target means postponing a device's ...

Physicists publish solution to the quantum measurement problem

(Phys.org) —Quantum mechanics is a highly successful theory, but its interpretation has still not been settled. In their recent opus magnum, Theo Nieuwenhuizen (Institute of Physics, UvA) and colleagues claim to have found ...

New record for measurement of atomic lifetime

Researchers at the Niels Bohr Institute have measured the lifetime of an extremely stable energy level of magnesium atoms with great precision. Magnesium atoms are used in research with ultra-precise atomic clocks. The new ...
