TL;DR: It is demonstrated that FePS3 exhibits an Ising-type antiferromagnetic ordering down to the monolayer limit, in good agreement with the Onsager solution for two-dimensional order-disorder transition.

TL;DR: Hot electrons become spatially localized at the centre of the graphene layer, resulting in a 1,000-fold enhancement in thermal radiation efficiency and paving the way towards the realization of commercially viable large-scale, atomically thin, flexible and transparent light emitters and displays with low operation voltage and graphene-based on-chip ultrafast optical communications.

TL;DR: This study provides a theoretical framework for understanding a wide range of phenomena closely related to the chiral anomaly in topological semimetals, such as magnetotransport, thermoelectric responses, and plasmons, to name a few.

TL;DR: This work was supported by the Creative-Pioneering Research Program through Seoul National University and Korean NRF No2016R1A1A 1A05919979, and by Grant No.

TL;DR: Ryoo et al. as discussed by the authors proposed the concept of hidden orbital polarization and proved that the hidden spin polarization is not a fundamental physical quantity but a secondary quantity that is completely derived from the hidden orbital polarizations.
