Inelastic neutron scattering was used to study the Cu-O bond-stretchingvibrations in optimally doped La1.85Sr0.15CuO4 (Tc = 35 K) and in two othercuprates showing static stripe order at low temperatures, i.e.La1.48Nd0.4Sr0.12CuO4 and La1.875Ba0.125CuO4. All three compounds exhibit avery similar phonon anomaly, which is not predicted by conventional bandtheory. It is argued that the phonon anomaly reflects a coupling to chargeinhomogeneities in the form of stripes, which remain dynamic in superconductingLa1.85Sr0.15CuO4 down to the lowest temperatures. These results show that thephonon effect indicating stripe formation is not restricted to a narrow regionof the phase diagram around the so-called 1/8 anomaly but occurs in optimallydoped samples as well.Comment: to appear in J.
