Electron-electron interaction effects in one-dimensional quantum wires are much less well understood than interactions in zero- or two-dimensional systems. One effect in particular that continues to attract interest is the `0.7 Structure’. I will briefly discuss the 0.7 Structure, before presenting several other new interaction effects in GaAs/AlGaAs quantum wires, occurring in high in-plane magnetic fields, and at zero magnetic field. I will then explain how these effects relate to eachother, and how they may help to explain the origin of the 0.7 Structure.
