Weak-coupling theory of half-metals and other fractional metallic phases in biased doped Bernal bilayer graphene
D. V. Zhitov, A. V. Rozhkov, A. O. Sboychakov +1
The paper presents a theoretical study of many-body electronic phases in doped and electrically biased Bernal-stacked (AB) bilayer graphene. We develop a variational mean-field the…
Ordered states of undoped AB bilayer graphene: bias induced cascade of transitions
A. V. Rozhkov, A. O. Sboychakov, A. L. Rakhmanov
Using mean-field theory, we determine the electronic phase diagram of undoped AB-stacked bilayer graphene in the presence of a transverse electric field. In addition to multiple co…
Nesting-driven ferromagnetism of itinerant electrons
Ya. I. Rodionov, A. V. Rozhkov, M. E. S. Beck +3
We theoretically investigate a model with electrons and holes whose Fermi surfaces are perfectly nested. The fermions are assumed to be interacting, both with each other and with t…
Umklapp-driven first-order transition into a charge-density wave phase
A. V. Rozhkov
Using phenomenological Landau free energy, we systematically analyze influence of so-called umklapp contributions on the phase diagram of a solid hosting a commensurate charge-dens…
