Quantum Lifshitz points and fluctuation-induced first-order phase transitions in imbalanced Fermi mixtures
We perform a detailed analysis of the phase transition between the uniform superfluid and normal phases in spin- and mass-imbalanced Fermi mixtures. At mean-field level we demonstrate that at temperature T→0 the gradient term in the effective action can be tuned to zero for experimentally relevant s...
