Abstract

We will discuss the effect of non-equilibrium drive near a quantum
critical point in itinerant electron systems. Non-equilibrium field
theory is formulated in terms of the Keldysh functional integral.
The renormalization group approach is used to study the universality
class of the non-equilibrium phase transition in the steady state system.
The role of the non-equilibrium drive in the quantum-classical crossover
will be discussed using the example of the Hertz-Millis theory and
the generalization thereof.
