Phys. Rev. Lett. 87, 066401 (2001) [4 pages]Bulk and Boundary Zero-Bias Anomaly in Multiwall Carbon NanotubesReceived 11 December 2000; published 18 July 2001 We compute the tunneling density of states of doped multiwall nanotubes including disorder and electron-electron interactions. A nonconventional Coulomb blockade reflecting nonperturbative Altshuler-Aronov-Lee power-law zero-bias anomalies is found, in accordance with recent experimental results. The presence of a boundary implies a universal doubling of the boundary exponent in the diffusive limit. © 2001 The American Physical Society URL:
