This work was a big step toward sustainable computing, because encoding data via spin waves (whose quasiparticles are called magnons) could eliminate the energy loss, or Joule heating, associated with electron-based devices. But at the time, the spin wave signals could not be used to reset the magnetic bits to overwrite existing data.

The new device involves a tiny silicon beam that vibrates at 5 gigahertz and couples to a microwave resonator—essentially a nanoscale box in which photons bounce around, also at 5 GHz. Using a technique called electrostatic actuation, developed previously by the Mirhosseini lab for quantum applications, a microwave photon gets converted within that box to a mechanical vibration of the beam, and that mechanical oscillation, with the help of laser light, gets converted by the r

Researchers at Westlake University have disclosed a two-dimensional (2D) mechanically interlocked polymer (MIP) that mimics medieval chainmail at the molecular scale. This micrometer-scale 2D material exhibits exceptional flexibility and stiffness, potentially revolutionizing next-generation lightweight protective gear and smart armor systems.

Physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a compact laser that emits extremely bright, short pulses of light in a useful but difficult-to-achieve wavelength range, packing the performance of larger photonic devices onto a single chip.
