Query: Scaling of Entanglement Entropy in the Random Singlet Phase   We present numerical evidences for the logarithmic scaling of the
entanglement entropy in critical random spin chains. Very large scale exact
diagonalizations performed at the critical XX point up to L=2000 spins 1/2 lead
to a perfect agreement with recent real-space renormalization-group predictions
of Refael and Moore [Phys. Rev. Lett. {\bf 93}, 260602 (2004)] for the
logarithmic scaling of the entanglement entropy in the Random Singlet Phase
with an effective central charge ${\tilde{c}}=c\times \ln 2$. Moreover we
provide the first visual proof of the existence the Random Singlet Phase thanks
to the quantum entanglement concept.
