Hydrogen is the simplest of atoms, but it hardly constitutes the simplest of liquids. When liquid hydrogen is subjected to extreme pressure, it is projected to take up a zero temperature liquid metallic state comprised of protonic and electronic fermi liquids, which both may undergo phase transitions to superconducting states. Due to number conservation of leptons and baryons, such superconducting condensates will be individually conserved and this leads to completely novel physics compared to what one observes in multi-component electronic condensates. One novel feature is the appearance of superfluid modes arising out of charged condensates. The talk will describe the resulting physics in both zero and finite magnetic field.
