How Quantum Mechanics Can Make Soundproofing?

Quantum mechanics is a branch of physics that studies and describes the fundamental phenomena in physical systems.

It sounds a bit complicated? Normal! Science is always a bit complicated…

Here we discover the work of Sebastian Huber, physicist who has dedicated his work to the study of materials whose ability to conduct electric current originates in their topology.

This article allows us to better understand what it is by demonstrating how a doughnut can be turned into a coffee cup by pulling, stretching and molding.

The easiest way to understand what “topological” means in this context is to imagine how a doughnut can be turned into a coffee cup by pulling, stretching, and molding—but without cutting it.

Topologically speaking, therefore, doughnuts and coffee cups are identical, and by applying the same principle to the quantum mechanical wave function of electrons in a solid we obtain the phenomenon of the topological insulator.

This is advanced quantum physics, highly complex and far removed from everyday experience. Nevertheless, Huber and his collaborators have now managed to make these abstract ideas very concrete and even to come up with a possible application in engineering.

Then of course, quantum mechanics is still far from coming to our studios!

But this type of study is very promising for the future.

This opens new doors, designs new directions and should definitely inspire what we will use tomorrow…

At present, we’re the lucky observers of progress!

Such properties would be interesting, for instance, in sound and vibration insulation, which is important in various areas such as industrial production, where robot arms have to place objects precisely and without jittering. Moreover, one can imagine materials that convey sound in one direction only, or others that focus sound like a lens.
