1 Non-Fermi Liquid Phases and Intertwined Orders in Semimetals
... perturbative RG approach to study the way in which a complex non-linear feedback between the various ordering tendencies involved leads to a situation in which, on intermediate length and temperature scales, these orders are intertwined. Under these conditions, small changes in the microscopic param ...
