Orthogonality catastrophe and Kondo effect in graphene [PDF]

open access: yes, 2007
Anderson's orthogonality catastrophe in graphene, at energies close to the Dirac point, is analyzed. It is shown that, in clean systems, the orthogonality catastrophe is suppressed, due to the vanishing density of states at the Dirac point.

Black Holes at the LHC [PDF]

open access: yes, 2001
If the scale of quantum gravity is near a TeV, the LHC will be producing one black hole (BH) about every second. The BH decays into prompt, hard photons and charged leptons is a clean signature with low background.
