“…It has been shown that the critical temperature of the superconducting transition can be substantially increased at low densities by considering spin-polarization or the two-band superconductivity scenario [31,32,33]. These results proved to be very important for related systems as in polarized 3 He - 4 He mixtures, imbalanced Fermi-gas in magnetic trap as well as for heavy fermion superconductors and other mixed valence systems described by the two-band Hubbard model with one narrow band [34,35,36,37]. Together with T.M.…”

“…These qualitative considerations press us to consider the superconductivity in metallic hydrogen on the level of Fermi-Fermi mixture [96] of protons and electrons (as in plasma physics or in the two components model with one very narrow band [36,37]) or on the level of Fermi-Bose mixture of Cooper pairs and protons or even of Bose-Bose mixture [97] of Cooper pairs and biprotons. Note that the ideas of Fermi-Bose mixture were very fruitful in low temperature physics describing the search for fermionic (BCS) superfluidity in dilute 3D and 2D solutions of 3 He in superfluid 4 He [34,98,99,100] as well as 6 7 Li Li - [101,102,103] in restricted geometry of magnetic and dipole traps or on the optical lattices.…”

In this review article we consider theoretically and give experimental support to the models of the Fermi-Bose mixtures and the BCS-BEC crossover compared with the strong-coupling approach, which can serve as the cornerstones on the way from high-temperature to room-temperature superconductivity in pressurized metallic hydrides. We discuss some key theoretical ideas and mechanisms proposed for unconventional superconductors (), superfluids and balanced or imbalanced ultracold Fermi gases in magnetic traps. We build a bridge between unconventional superconductors and recently discovered pressurized hydrides superconductors H3S and LaH10 with the critical temperature close to room temperature. We discuss systems with line of nodal Dirac points close to the Fermi surface and superconducting shape resonances, and hyperbolic superconducting networks which are very important for the development of novel topological superconductors, for the energetics, for the applications in nano-electronics and quantum computations.
