The superconducting phase of the high-Tc cuprates has been thought to bedescribed by a single d-wave pairing order parameter. Recently, there has beengrowing evidence suggesting that another form of order, possibly inherited fromthe pseudogap phase above Tc, may coexist with superconductivity in theunderdoped regime. Through a combined study of scanning tunneling microscopyand angle-resolved photoemission spectroscopy, we report the observation of twodistinct gaps (a small-gap and a large-gap) that coexist both in real space andin the anti-nodal region of momentum space in the superconducting phase ofBi2Sr2-xLaxCuO6+delta. We show that the small-gap is associated withsuperconductivity. The large-gap persists to temperatures above the transitiontemperature Tc and is found to be linked to short-range charge ordering.Remarkably, we find a strong, short-ranged correlation between the local small-and large- gap magnitudes suggesting that the superconductivity and chargeordering are affected by similar physical processes.
