Chiral superconductors are expected to carry a spontaneous, chiral and perpetual current along the sample edge. However, despite availability of several candidate materials, such has not been observed in experiments. In this article, we suggest an alternative probe form impurity-induced currents. We first demonstrate that single non-magnetic impurity induces encircling current. Its direction de...

18 or 22 π? 8 × 22! Quantum chemical calculations reveal the complex ring-current pathways of a new class heteroporphyrinoids.

The existence of spin-currents in absence any driving external fields is commonly considered an exotic phenomenon appearing only quantum materials, such as topological insulators. We demonstrate instead that equilibrium spin currents are a rather general property materials with non negligible spin-orbit coupling (SOC). Equilibrium can be present at the surfaces slab. Yet, we also propose global...

Actions of adenosine triphosphate (ATP) on neurons of the substantia gelatinosa (SG) were evaluated in spinal cord slices using tight-seal, whole-cell recordings. Bath-applied ATP activated a fast inward current and potentiated both glutamate-induced and synaptically evoked currents by acting through a purinergic receptor with the pharmacology of the P2 type. ATP also induced a delayed slow out...

Light duration and intensity influence classical conditioning in Hermissenda through their effects on the light-induced currents. Furthermore, the contribution of voltage-dependent potassium currents to the long-lasting depolarization in type B photoreceptors depends on light-induced currents active at resting potentials. Thus, the present study measures the effect of holding potential, duratio...
