Informācija par kolokviju (angļu valodā):
The quantum Hall effect is a striking manifestation of quantum properties that lead to a quantization of electrical transport in two-dimensional systems under a high magnetic field. This effect is also accompanied by the appearance of edge channels that act as 1D wires that conduct the current only on the edge of the sample. This behavior allows us to realize an Fabry-Perot interferometer that can be used to detect quantum radiation with a very high temporal resolution. In this presentation I will discuss the fundamentals of the quantum Hall effect and the underlying physical phenomena and then describe our recent experiment [1] that demonstrates the principle of the radar in these systems.
