OLED-based displays are now ubiquitous, and yet the very way positive and negative charges interact with each other to generate excitons and the overall fate of these species in the process of light emission still holds several mysteries. By investigating the operation of OLEDs containing protonated or deuterated organic semiconductors at low temperatures and moderate magnetic fields, the authors reveal here a nonmonotonic dependence of OLED light intensity on magnetic field, which is magnetoelectroluminescence. This enables distinction of interactions between carriers and molecular excitations.

]]>Kagome metals are exciting platforms to explore electronic instabilities such as charge density waves. The authors study here magnetotransport properties of various kagome compounds, with a focus on the charge density wave metal ScV${}_{6}$Sn${}_{6}$ and explain characteristic features among them. For example, ScV${}_{6}$Sn${}_{6}$ and CsV${}_{3}$Sb${}_{5}$ both have charge density waves, and both exhibit sublinear resistivity above the charge ordering temperature and anomalous Hall-like behavior below this temperature. This contrasts with LuV${}_{6}$Sn${}_{6}$, which lacks charge ordering and lacks these intriguing transport hallmarks.

Considering a quantum dot with Kramers degenerate doublets of Majorana zero modes in time-reversal invariant triplet superconductors with strong charging energy effects and order parameter fluctuations, the authors suggest here a setup realizing a novel Kondo fixed point. Using Abelian bosonization, they show that the system displays Fermi-liquid and non-Fermi-liquid ground state characteristics alike.
