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…
Anomalous superconductivity and unusual normal state properties of bilayer and twisted graphene (Brief review)
M. Yu. Kagan, M. M. Korovushkin, V. A. Mitskan +4
It has been shown that the Kohn--Luttinger superconductivity mechanism interplaying with other types of ordering can be implemented in systems with a hexagonal lattice. A number of…
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…
Ordered states in AB bilayer graphene in SU(4)-symmetric model
A. V. Rozhkov, A. O. Sboychakov, A. L. Rakhmanov
We apply SU(4)-symmetric model to examine possible ordered states in AB stacked bilayer graphene (AB-BLG). The Hamiltonian of the system possesses this symmetry under certain assum…
Evidence for spin droplets (ferrons) formation in the heavy fermion metal CeB with dynamic charge stripes
A. N. Azarevich, O. N. Khrykina, N. B. Bolotina +13
The presented studies of resistivity (R), thermal conductivity (k) and specific heat (C) at low temperature 1.8-7 K in magnetic field up to 90 kOe made it possible to detect for th…
