Normal state diamagnetism of charged bosons in cuprate superconductors

Normal state orbital diamagnetism of charged bosons quantitatively accounts for recent highresolution magnetometery results near and above the resistive critical temperature Tc of superconducting cuprates. Our parameter-free descriptions of normal state diamagnetism, Tc, upper critical fields and specific heat anomalies unambiguously support the 3D Bose-Einstein condensation of preformed real-space pairs with zero off-diagonal order parameter above Tc at variance with phase fluctuation scenarios of cuprates.
