Sound

Scientists successfully controlled individual light quanta at very high speed

Nanoscale soundwave controls photons on a chip – milestone on the way towards hybrid quantum technologies.

A new quantum phase discovered for developing hybrid materials

The structural phase transition is driven by an acoustic soft mode.

Using sound to model the world

This machine-learning system can simulate how a listener would hear a sound from any point in a room.

A new mechanism discovered that controls the sound flow

This gives rise to a lasing effect for sound.

MIT neuroscientists developed a computer model that can localize sounds

We now have a model that can actually localize sounds in the real world

Activity in brain while switching between hearing and listening

Attention alters activity in brain areas.

Sound-light pulses observed in 2D materials for the first time

Scientists recorded the propagation of combined sound and light waves in atomically thin materials.

Study explains how sound waves travel through disordered materials

This work may lead to new heat- and shatter-resistant glass for smartphones and tablets.

For the first time, physicists captured the sound of a perfect liquid

The results should help scientists study the viscosity in neutron stars, the plasma of the early universe, and other strongly interacting fluids.

The upper limit for the speed of sound found

It is around twice as fast as the speed of sound in diamond.

Sound can be used in high-resolution imagery, study

Deep learning and metamaterials make the invisible visible

Aliens might be using a black hole to generate energy

In 1969, British physicist Roger Penrose put an idea on the table that energy could be generated by lowering an object into the black...
