Disorder in Large-N Theories

Understand

We consider Euclidean Conformal Field Theories perturbed by quenched disorder, namely by random fluctuations in their couplings.

• Such theories are relevant for second-order phase transitions in the presence of impurities or other forms of disorder.
• Theories with quenched disorder often flow to new fixed points of the renormalization group.
• We begin with disorder in free field theories.
