Fermions in a graphene sheet behave like massless particles. We show that by folding the sheet into a tube they acquire non-zero effective mass as they move along the tube axis. That is, changing the...

We present a scheme to realize a deterministic solid state source of time-bin entangled photon pairs using cavity-assisted stimulated Raman adiabatic passage (STIRAP) in a single quantum dot. The quan...

We summarize the low energy features of a supersymmetric class of models with bilinear R-parity violation. We
analyze two cases where the supersymmetry breaking is mediated either by supergravity or ...
