This scientist developed a theory of interacting particles which imagines that the excited states of the interacting particles correspond to the excited states. That theory allows the use of adiabatically switched on quasiparticles with mean field theory derived energies to represent the interaction. In addition to that Fermi liquid theory, this scientist has a namesake free energy that is a power series of the order parameter and that is minimized with respect to that order parameter. In addition to that theory of second-order (*) phase transitions, this man was the first to develop a theory that explained why helium-4 had 0 viscosity at low enough temperature. From that theory, with Ginzburg, he developed a theory of superconductivity. For 10 points, name this Russian scientist who developed a theory of superfluidity.
