We study the presence of Pomeranchuk instabilities induced by interactions on a Fermi liquid description of a graphene layer. Using a recently developed generalization of Pomeranchuk method we present a phase diagram in the space of fillings versus on-site and nearest neighbors interactions. Interestingly, we find that for both interactions being repulsive an instability region exists near the Van Hove filling, in agreement with earlier theoretical work. In contrast, near half filling, the… Expand

Pomeranchuk instabilities in multicomponent lattice systems at finite Temperature
In the present paper we extend the method to detect Pomeranchuk instabilities in lattice systems developed in previous works to study more general situations. The main result presented here is theExpand
Pomeranchuk instabilities in holographic metals
We develop a method to detect instabilities leading to nematic phases in strongly coupled metallic systems. We do so by adapting the well-known Pomeranchuk technique to a weakly coupled system ofExpand
Topological Fermi liquids from Coulomb interactions in the doped honeycomb lattice.
TLDR
It is shown that when the unit cell is enlarged to host six atoms that permits Kekulé distortions, self-consistent currents spontaneously form creating nontrivial magnetic configurations with total zero flux at high electron densities. Expand
Fermi surface instabilities at finite temperature
We present a new method to detect Fermi surface instabilities for interacting systems at finite temperature. We first apply it to a list of cases studied previously, recovering already known resultsExpand

Magnetic-flux-driven topological quantum phase transition and manipulation of perfect edge states in graphene tube
TLDR
This model has different nontrivial topological phases as the flux changes, including two perfect midgap edge states, in which the particle is completely located at the boundary, even for a tube with finite length. Expand

We find an exotic spin excitation in a magnetically ordered system with spin orbit magnetism in 2D, where the order parameter has a net spin current and no net magnetization. Starting from a FermiExpand
