A quasiparticle is a disturbance or excitation (e.g. spin waves, bubbles, etc.) that behaves as a particle and could therefore be regarded as one. Long-range interactions between quasiparticles can give rise to a 'drag,' ...
Computers, cell phones and other devices are built from many small parts and components that are prone to poor performance and damage caused by overheating. As such, there is a market demand to develop machine parts that ...
