Researchers at SLAC National Accelerator Laboratory and Stanford University discovered that focusing intense, circularly polarized laser light on a topological insulator generates harmonics that can be used to probe electron behavior in the material's topological surface, a sort of electron superhighway where electrons flow with no loss. The technique should be applicable to a wide range of quantum materials.

Figure 1: To make EVs and charging stations compatible, independent of whether they use the same voltage, the power delivery network uses a Vicor non-isolated fixed-ratio bus converter module (NBM) to convert either 800V to 400V or 400V to 800V at 6kW. This high-efficiency, high-density, scalable solution enables EVs of different battery voltages to utilize the same charging stations
