In low-dimensional systems, such as LaAlO3/SrTiO3 oxide interfaces, the occurrence of an APHE has been reported and is due to a Zeeman-induced modification of local concentrations of the out-of-plane Berry curvature, which, when integrated over…

Pure-blue single-layer organic light-emitting diodes based on trap-free hyperfluorescence
Even though organic light-emitting diodes (OLEDs) are an established technology used in high-end displays, blue OLEDs are still not up to par with their green and red counterparts. Blue fluorescent emitters as used in displays exhibit decent…

Brightening dark excitons and trions in systems with a Mexican-hat energy dispersion: example of InSe
Monolayer InSe
InSe is a III–VI chalcogenide (metal-group III atom and group VI chalcogenide), with a hexagonal structure with unit vectors \({{\boldsymbol{a}}}_{1}=\left(a/2,\sqrt{3}a/2\right)\) and

This Blue Laser Just Solved a 150-Year Physics Mystery
For over a century, physicists knew a strange magnetic signal should exist in everyday metals like copper and gold, but they couldn’t see it. Now, using only a blue laser and a clever tweak to a classic technique, scientists have detected this…
