Article Synopsis
- Thin films of ferromagnetic topological insulators can achieve the quantum anomalous Hall effect without needing an external magnetic field.
- Researchers demonstrated crossed Andreev reflection in a system where a superconducting Nb electrode interacts with a chiral edge state, indicating superconducting pair formation.
- Their findings suggest a significant link between superconductivity and chiral edge states, paving the way for further exploration of topological superconductivity and Majorana zero modes.
Article Synopsis
- The study investigates the thermal decomposition of 2-cyclopentenone during biomass pyrolysis, utilizing both experimental techniques and theoretical models.
- Gas-phase pyrolysis experiments were conducted at high temperatures, revealing various products like carbon monoxide and different hydrocarbons through FTIR spectroscopy.
- Five distinct decomposition pathways were identified, including multiple H atom migrations and C-C bond ruptures, leading to the formation of compounds such as acrolein, propane derivatives, and intermediates like cyclopropenone.

Here, we report that in very low carrier-density samples of ZrTe_{5}, when the current and the magnetic field are both along the crystallographic a axis, the current-voltage characteristics presents a pronounced nonlinearity which tends to saturate in the ultra quantum limit. The magnetic-field dependence of the nonlinear coefficient is well explained by the Boltzmann theory for flat-band transport, and we argue that this nonlinear transport is likely due to the combined effect of flat bands and charge puddles; the latter appear due to very low carrier densities.
