Discovery of the one-way superconductor, thought to be impossible

Associate professor Mazhar Ali and his research group at TU Delft have discovered one-way superconductivity without magnetic fields, something that was thought to be impossible ever since its discovery in 1911—up until now. ...

New parity-time symmetric system opens up range of wavelengths to researchers, engineers

Researchers from the labs of Lan Yang, the Edwin H. & Florence G. Skinner Professor, and Xuan "Silvia" Zhang, associate professor, at the McKelvey School of Engineering at Washington University in St. Louis, have developed ...

All-optical attoclock for imaging tunnelling wavepackets

Physicists can study the possible time delays of light-induced tunneling of an electron from an atom after conducting measurements of time delays when cold atoms tunnel through an optically created potential barrier. In a ...

Physicists report on 'quantum boomerang' effect in disordered systems

Physicists at UC Santa Barbara have become the first to experimentally observe a quirky behavior of the quantum world: a "quantum boomerang" effect that occurs when particles in a disordered system are kicked out of their ...

Study sheds light on axion dark matter

Scientists from Durham University and Kings College London have presented a theoretical review in a new study strongly supporting the search for axion dark matter.

New insight into unconventional superconductivity

The kagome pattern, a network of corner-sharing triangles, is well known amongst traditional Japanese basket weavers—and condensed matter physicists. The unusual geometry of metal atoms in the kagome lattice and resulting ...

New materials for quantum technologies

While conventional electronics relies on the transport of electrons, components that convey spin information alone may be many times more energy efficient. Physicists at the Technical University of Munich (TUM) and the Max ...

Physicists exploit space and time symmetries to control quantum materials

Physicists from Exeter and Trondheim have developed a theory describing how space reflection and time reversal symmetries can be exploited, allowing for greater control of transport and correlations within quantum materials.

A new way to generate electricity from waste heat: Using an antiferromagnet for solid devices

Forcing electrons to flow perpendicularly to a heat flow requires an external magnetic field—this is known as the Nernst effect. In a permanently magnetized material (a ferromagnet), an anomalous Nernst effect (ANE) exists ...

Study gathers evidence of topological superconductivity in the transition metal 4Hb-TaS2

Topological superconductors are a class of superconducting materials characterized by sub-gap zero energy localized modes, known as Majorana boundary states (MBSs). These materials are promising for the development of quantum ...
