Polaritons open up a new lane on the semiconductor highway
On the highway of heat transfer, thermal energy is moved by way of quantum particles called phonons. But those phonons don’t remove enough heat at the nanoscale of today’s most…
Luttinger’s theorem at the core of topological matter
Luttinger’s theorem relates a Fermi liquid’s particle density to the volume of its Fermi surface. Credit: Wikimedia Commons, Public Domain In 1960, Joaquin Luttinger introduced a universal statement that relates…
A novel microscope operates on the quantum state of single electrons
Artistic illustration of the integration of electron spin resonance in atomic force microscopy. The white structure at the bottom represents a single molecule, the arrows its spin quantum state and…
