Droplets Formation, BEC and Superconductivity in Quantum Gases, Metallic Hydrogen and Excitonic Systems

We analyze different droplets, which arise in superconducting and superfluid (Bose-condensed)Bose-condensed system systemsSuperfluidsystem ranging from imbalanced and dipole Fermi gases, Fermi–Bose mixtures with dominant number ofBoson bosons, metallic hydrogen droplets near theBoundarybetween phases phase boundary between atomicLiquidmolecular and molecular liquid and crystalline phases, as well as in excitonic systems inCollapsein self-similar collapse regime the self-similar collapse regime. We study also long-rangeOscillationcharge charge oscillations and formation of the inhomogeneous phases related to acoustic plasmons in MgB \(_2\) .
