Quantum materials: A new state of matter with chiral properties
An international research group has discovered a new state of matter characterized by the existence of a quantum phenomenon called chiral current. These currents are generated on an atomic scale by a cooperative movement of electrons, unlike conventional magnetic materials whose properties originate from the quantum characteristic of an electron known as spin and their
Quantum simulation with ultracold fermions unveils pairing pseudogap
A research team has, for the first time, observed and quantitatively characterized the many-body pairing pseudogap in unitary Fermi gases. This achievement, pursued by the ultracold atomic community for nearly two decades, resolves longstanding debates regarding the existence of a pairing pseudogap in these gases. It also supports pairing as a possible origin of the
Hall effect uncovers hidden symmetry in spin-ice
Physicists from the University of Augsburg succeeded in distinguishing chiral orders with similar magnetization but an opposite sense of rotation through electrical measurements at low temperatures. This is relevant for fundamental research on complex magnets and possible applications for magnetic data storage. The results were published in Nature Physics.Quantum Physics NewsRead More
