I would like to add the label "Omega" on top of the lateral bar in my density plot, like this (I did it using paint):

Example of density plot

I spent hours on the documentation, but I didn't find how to obtain such a trivial thing...

    $\begingroup$ Use the option PlotLegends -> BarLegend[Automatic, LegendLabel -> "Omega"]? $\endgroup$

Explicitly specify the PlotLegend as a BarLegend then you can use the option LegendLabel

DensityPlot[Sin[x] Sin[y],
 {x, -4, 4}, {y, -3, 3},
 PlotLegends -> BarLegend[Automatic, LegendLabel -> "Omega"]]
