Magnetic excitations in honeycomb ruthenate Na2RuO3
Honeycomb magnets with strong spin-orbit coupling (SOC) are expect to produce exotic magnetic ground states as exemplified by d5 iridates with Jeff = 1/2 state. In d4 case, SOC... -
The effect of a vanishing pseudogap on the magnetic excitations in overdoped ...
One of the major issues in high temperature superconductivity is the nature of the so called pseudogap phase. A related question is whether the pseudogap controls the evolution... -
Water Binding and Solvent Dynamics in Natural Deep Eutectic Solvents
Deep Eutectic Solvents (DES) are molecular mixtures similar to ionic liquids, having melting points below room temperature. However instead of being composed of a salt, the... -
