Description
Summary:We found that thermodynamic quantum time crystals in Fermi systems, defined as quantum orders oscillating periodically in the imaginary Matsubara time with zero mean, are metastable for two general classes of solutions. Mean-field time independent solutions proved to have lower free energy manifesting true thermodynamic equilibrium with either single or multiple (competing) charge, spin, and superconducting symmetry breaking orders. The "no-go" theorem is proven analytically for a case of long-range interactions between fermions in momentum space in electron-hole and Cooper channels.
