Competition between Pomeranchuk instabilities in the nematic and hexatic channels in a two-dimensional spinless Fermi fluid
Daniel G. Barci, Marta Trobo, Victoria Fernández +1
We study the competition between the nematic and the hexatic phases of a two-dimensional spinless Fermi fluid near Pomeranchuk instabilities. We show that the general phase diagram…

Non-perturbative behavior of the quantum phase transition to a nematic Fermi fluid
Michael J. Lawler, Victoria Fernandez, Daniel G. Barci +2
We discuss shape (Pomeranchuk) instabilities of the Fermi surface of a two-dimensional Fermi system using bosonization. We consider in detail the quantum critical behavior of the t…
