Quantum phase transition found in a quasi-2D system consisting purely of spins

Publicado em 12 julho 2021
Pure quantum systems can undergo phase transitions analogous to the classical phase transition between the liquid and gaseous states of water. At the quantum level, however, the particle rotates in states that arise from phase transitions, showing collectively entangled behavior. This unexpected observation offers a new way to produce materials with topological properties that are useful in spintronics and quantum computing applications. The discovery was made by an international collaborator [...]
