      abstract     = {Here, we reinvestigate the underlying charge and magnetic
                      correlations in La2−xSrxCoO4 within a combined study of
                      muon spin relaxation (μSR), x-ray photon correlation
                      spectroscopy, synchrotron radiation single-crystal x-ray
                      diffraction, and neutron-scattering measurements. For
                      La2−xSrxCoO4 around 1/3 hole-doping, the significant
                      charge correlations that are responsible for the emergence
                      of hour-glass magnetic spectra are found to be slowly
                      fluctuating checkerboard charge ordering (CBCO) correlations
                      with an onset temperature being independent of hole-doping.
                      This reveals a local origin of the CBCO correlations in the
                      rather ionic cobaltates, thus being distinct from the more
                      covalent nickelates. Moreover, we report the observation of
                      a very similar temperature dependence of the intensities of
                      in-plane high- and low-energy excitations within the
                      La2−xSrxCoO4 hour-glass spectrum. This observation shows
                      that nano phase separation is distinct from conventional
                      phase separation and that there is a coupling between
                      nanometer-sized undoped and hole-doped islands. Based on
                      this, it is possible to propose a microscopic scenario for
                      the suppression of the outwards-dispersing branches in
                      hour-glass magnetic spectra.},
