Puzzling effects Two quantum simulations have revealed unexpected behaviour at quantum phase transitions. (Courtesy: Shutterstock/Inna-Bigun) Unexpected behaviour at phase transitions between ...

interactions with external magnetic fields, and relaxation processes. The second portion of the course will discuss basic concepts of image formation, including radiofrequency pulse excitation, ...

Two companies have collaborated to expand the product range of magnet-free electric motors to upper-segment applications.

Permanent magnet synchronous motors (PMSMs) are AC synchronous motors that receive field excitation by permanent magnets. These motors have sinusoidal back-EMF and are similar to brushless DC (BLDC) ...

Consider an undamped single degree-of-freedom system experiencing harmonic excitation whose equation of motion (EOM) is given by: Here omega n is known as the natural frequency of response. The ...

Physicists in the US, Europe and Korea have produced a long-lasting light-driven magnetic state in an antiferromagnetic material for the first time. While their project started out as a fundamental ...

Their setup included a custom-built microspectroscope with a high numerical aperture objective lens, a continuous-wave diode laser for excitation, and optical filters to isolate fluorescence signals.
