Description:
Author(s): R. Mahajan, D. M. Ramirez, S. Kachru, and S. Raghu We study the problem of disorder-free metals in the vicinity of a quantum critical point in d =3+1 dimensions. We begin with perturbation theory in the Yukawa coupling between the electrons and undamped bosons (order-parameter fluctuations) and show that the perturbation expansion breaks down below e...
