Infinite dimensions<br />
U/D=1<br />
U/D=2<br />
Transfer of spectral weight<br />
from the quasiparticle peak<br />
to the Hubbard bands<br />
U/D=2.5<br />
U/D=3<br />
U/D=4<br />
<strong>The</strong> gap between the<br />
Hubbard bands<br />
opens in the metallic state<br />
Quasiparticles disappear at the <strong>Mott</strong> <strong>transition</strong><br />
