The electron-hole liquid in MoTe2

In this 3D visualization we see the formation of an unusual state of matter, the electron-hole liquid in MoTe2. Normally in MoTe2, energy absorbed from light becomes a gas of electrons (orange dots), holes (blue dots) and excitons (orange and blue pairs). But if this light is generated by a very intense source, like an ultrafast pulsed laser, it can create so many electrons and holes that some of them condense into an electron-hole liquid. This process is very similar to the formation of water droplets from
