    • T = 0.6/1000 K. The boundary of the crossover regime is not sharply defined. For the line shown in Fig. 1, we used the criterion that dη/dx is becoming small, i.e., 25% of its maximal value at the same T.

    • 0, which includes lattice contributions via a normal compressibility K, has a negative curvature with respect to volume V above the DMFT critical point [P. Majumdar and H. R. Krishnamurthy, Phys. Rev. Lett. 73, 1525 (1994)]. This gives rise to a thermodynamic instability as in the liquid gas transition or the Kondo volume collapse scenario for Ce [ J. W. Allen and R. M. Martin, Phys. Rev. Lett. 49, 1106 (1982)].

    • note
    • A small contribution to the 500 eV spectrum from Cr 3d emission has been removed by using information obtained from resonant photoemission spectra at the V 2p edge, for which the Cr emission is entirely suppressed, and from PI phase spectra for a much smaller value of x.

    • note
    • A temperature cycle sometimes produces a small (≈0.1 eV) shift of the chemical potential, indicating some change of the surface states.
