Spin-valley half-metal in systems with Fermi surface nesting
A. L. Rakhmanov, A. O. Sboychakov, K. I. Kugel +2
Half-metals have fully spin polarized charge carriers at the Fermi surface. Such polarization usually occurs due to strong electron--electron correlations. Recently [Phys. Rev. Let…
Many-body effects in twisted bilayer graphene at low twist angles
A. O. Sboychakov, A. V. Rozhkov, A. L. Rakhmanov +1
We study the zero-temperature many-body properties of twisted bilayer graphene with a twist angle equal to the so-called `first magic angle'. The system low-energy single-electron…
Disentangling amplitude and phase dynamics of a charge density wave in a photo-induced phase transition
Alfred Zong, Anshul Kogar, Ya-Qing Bie +16
Upon excitation with an intense ultrafast laser pulse, a symmetry-broken ground state can undergo a non-equilibrium phase transition through pathways dissimilar from those in therm…
Disorder correction to the Néel temperature of ruthenium-doped BaFeAs: Theoretical analysis
S. V. Kokanova, A. V. Rozhkov
We analyze theoretically nuclear magnetic resonance data for the spin-density wave phase in the ruthenium-doped BaFeAs. Since inhomogeneous distribution of Ru~atoms introdu…
Scattering on a rectangular potential barrier in nodal-line Weyl semimetals
D. A. Khokhlov, A. L. Rakhmanov, A. V. Rozhkov
We investigate single-particle ballistic scattering on a rectangular barrier in the nodal-line Weyl semimetals. Since the system under study has a crystallographic anisotropy, the…
