Pushing boundaries: Detecting the anomalous Hall effect without magnetization in a new class of materials

An international research team has discovered the anomalous Hall effect in a collinear antiferromagnet. More strikingly, the anomalous Hall effect emerges from a non-Fermi liquid state, in which electrons do not interact according to conventional models. The discovery not only challenges the textbook framework for interpreting the anomalous Hall effect but also widens the range

Unlocking the secrets of superfluid: Scientists unveil how dipolar interactions shape two-dimensional superfluid behavior

An international team of physicists has made a significant observation of the BKT phase transition in a 2D dipolar gas of ultracold atoms. This groundbreaking work marks a major milestone in understanding how 2D superfluids behave with long-range and anisotropic dipolar interactions.

A new take on the abilities of hydrogen binding energy for use in single atom catalysts

Conventional thinking holds that the metal site in single atom catalysts (SACs) has been a limiting factor to the continued improvement of the design and, therefore, the continued improvement of the capability of these SACs. More specifically, the lack of outside-the-box thinking when it comes to the crucial hydrogen evolution reaction (HER), a half-reaction resulting

Green hydrogen: A cage structured material transforms into a performant catalyst

Clathrates are characterized by a complex cage structure that provides space for guest ions too. Now a team has investigated the suitability of clathrates as catalysts for electrolytic hydrogen production with impressive results: the clathrate sample was even more efficient and robust than currently used nickel-based catalysts. They also found a reason for this enhanced
