We relate the phase separation observed in many crystals with pronounced electron correlations to the regions of negative electron compressibility. They were found in several models describing strong electron correlations. At low temperatures, these regions arise near chemical potentials corresponding to the change of the ground state in the site Hamiltonian. The negative electron compressibility leads to the separation of the system into electron-rich and electron-poor domains. The energy…

Phonon-Induced Emergent Charge Order in Cuprates
Charge-density modulations are inevitably accompanied by a distortion of the crystalline lattice. Electronic or phononic origins of charge order are therefore difficult to distinguish. Here we
