DMRG calculations provide evidence that Kondo-Heisenberg chains realize an interior-gap PDW superconducting state whose momentum distribution shows a characteristic hump or dip structure generated dynamically by interactions.
Majorana flat bands in topological superconductors cause the system to form pair density waves or phase crystals that lower free energy by gapping zero-energy states, with the uniform solution never surviving at zero temperature.
