Description
It has been shown in the framework of effective models that the QCD phase diagram as in three color case as well as in two color one possesses dualities. This means that various phenomena are dual with respect to each other. Then dualities were shown in a more and more general settings. Then finally dualities has been shown from first principles,three dualities as in two color QCD and one in three color one. The fact that dualities have been shown from first principles, i. e. in QCD itself, expanded their possible application much further.
In the talk I discuss two interesting applications. (i) studies of speed of sound at various chemical potentials (ii) studies of possible inhomogeneous phases of QCD phase diagram, including rather unexpected ones.
The talk is partly based on
