Physicists have been trying to observe the Kondo cloud quantum phenomenon for many decades. An international research team including a scientist from City University of Hong Kong (CityU) has recently developed a novel device that successfully measures the length of the Kondo cloud and even allows for controlling it. The findings can be regarded as a milestone in condensed matter physics, and may provide insights for understanding multiple impurity systems such as high-temperature superconductors.
Dr. Ivan Valerievich Borzenets, assistant professor at CityU's Department of Physics, collaborated with scientists from Germany, Japan and Korea. Their research findings were published in Nature.
