\section{Introduction} \label{sec:I} Phase transitions that occur in a quantum mechanical system at zero temperature ($T=0$) as a function of some non-thermal control parameter are called quantum phase transitions.

\section{Introduction} At HERA energies interactions between almost real photons (of virtuality $P^2 \approx 0$) and protons can produce jets of high transverse energy ($E_T^{jet}$). A significant fraction of these jets are expected to arise from charmed quarks. The presence of a `hard' energy scale means that perturb...
