Observing the Quantum World: Vanishing Electrons during Cooling
Researchers at the University of Bonn and ETH Zurich have observed a unique effect in the quantum world where electrons slowly vanish during cooling. This phenomenon, known as critical slowing down, occurs during phase transitions and is typically observed in bosons. However, the researchers have now demonstrated that it can also occur in fermions, such as electrons. By studying the collapse of quasiparticles, which are a superposition of immobile and mobile electrons, the researchers gained new insights into the exotic world of quantum physics. The findings contribute to a better understanding of phase transitions and may have implications for quantum information technology.
