An experiment with ultracold atoms reveals that a strongly driven quantum system doesn’t always heat up as expected. In daily life, doing work on something over and over usually makes it warmer. You ...

Conduction is the direct flow of heat from your warm body into your colder surroundings. In winter, all that heat escaping ...

Heat is supposed to need something to cling to, whether vibrating atoms in a metal rod or infrared light streaming from a hot stove. Yet a series of recent experiments suggests that empty space is not ...

This infographic depicts a simplified diagram of the novel energy-harvesting technique using the TL liquid. Implementation of this strategy in practice could help in the conversion of waste heat ...

Physicists at the University of Colorado Boulder have developed a new window insulation material that could dramatically cut energy loss from buildings without blocking the view outside. The material ...

Physicists at the University of Colorado Boulder have designed a new material for insulating windows that could improve the energy efficiency of buildings worldwide—and it works a bit like a high-tech ...
