Topological phase detected in spin chains

In some materials, there are phases between which a transition is not possible because they are protected by a certain form of symmetry. Physicists refer to these as topological phases. One example of this is the Haldane ...

Determining when a material becomes 'glassy'

Is it in a liquid phase or a 'glassy' phase? This question has been the subject of intense debate as physicists try to understand the behavior of so-called 'active matter'—a relatively new type of matter where particles ...

Modeling quantum spin liquids using machine learning

The properties of a complex and exotic state of a quantum material can be predicted using a machine learning method created by a RIKEN researcher and a collaborator. This advance could aid the development of future quantum ...
