Insulators are materials in which electrons cannot move freely. Past theoretical studies predicted the existence of an unusual insulating state dubbed obstructed atomic insulator (OAI), in which ...

Quantum bounds revealed: RIKEN researchers derived limits for three measurable parameters in solids, offering fresh insights into quantum material behavior. Mapping quantum state space: The study uses ...

Two RIKEN physicists have established new theoretical limits for experimentally measurable quantities by viewing solids through a lens of quantum geometry. Their results shed light both on the physics ...

Unexpected atomic reversal: Researchers saw atoms in a crystal switch rotational direction during angular momentum transfer, a first in experimental physics. Terahertz laser control: Intense terahertz ...
