Ultra-small nanocrystals are nanoscale materials with dimensions of a few nm.Since the size of ultra-small nanocrystals is comparable to or even smaller tha
Recent years have witnessed both experimentally and theoretically that a lot of quantum correlated many-body systems reveal exotic quantum states that yet n
The recent Princeton experimental realization of superconducting Fe-chains with ferromagnetic ordering opened a new direction in searching for Majorana zero
