In a groundbreaking experiment, scientists have built a quantum system where energy flows freely without ever slowing down.

A multi-disciplinary team of researchers linked atomic-scale features to efficient heat-to-electricity conversion, offering ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

Researchers at TU Wien have discovered a quantum system where energy and mass move with perfect efficiency. In an ultracold ...

One of the great successes of 20th-century physics was the quantum mechanical description of solids. This allowed scientists to understand for the first time how and why certain materials conduct ...

Researchers at TU Wien have developed a one-dimensional “quantum wire” using a gas of ultracold atoms. In this system, both ...

Abstract: The lunar mineral spectrometer (LMS) onboard the Chang’e-5—China’s lunar exploration mission—collected in situ multispectral data up to $3~\mu \text{m}$ over a large area of the lunar ...

Abstract: Because of its simple structure, large torque and high efficiency, permanent magnet synchronous motor of low speed and high torque is widely adopted in many fields. In this paper, a 394.5kW ...
