Nematic Phase Transitions in Multilayer Graphene Systems
R. David Mayrhofer, Andrey V. Chubukov
Recent experiments on graphene multilayers under displacement field have demonstrated a wide variety of electronically ordered phases, including valley and/or spin polarized phases…
Stoner Transition at Finite Temperature in a 2D Isotropic Fermi Liquid
R. David Mayrhofer, Megan Schoenzeit, Andrey V. Chubukov
We present the results of a mean-field analysis of the temperature evolution of a ferromagnetic Stoner transition in a two-dimensional (2D) system with an isotropic dispersion $\va…
Valley and Spin Polarized States in Bernal Bilayer Graphene
R. David Mayrhofer, Andrey V. Chubukov
We present the results for the evolution of the Fermi surfaces under variation of number density and displacement field for spin and valley-polarized states in Bernal bilayer graph…
Fermi Liquid near a q=0 Charge Quantum Critical Point
R. David Mayrhofer, Peter Wölfle, Andrey V. Chubukov
We analyze the quasiparticle interaction function (the fully dressed and antisymmetrized interaction between fermions) for a two-dimensional Fermi liquid at zero temperature close…
