Quantum Effects at a Spin-Flop Transition in the Antiferromagnetic Topological Insulator MnBiTe
V. V. Val'kov, A. O. Zlotnikov, A. Gamov +2
It is shown that the experimentally detected features in the low-temperature behavior of the magnetization in an external magnetic field perpendicular to the layers of manganese io…
Coexistence of gapless and gapped vortex modes with Majorana corner states in a 2D second-order topological superconductor
A. D. Fedoseev, A. O. Zlotnikov
Although the appearance of vortex-localized states with zero energy in first-order topological superconductors is well known, their possibility to form in the higher-order topologi…
Effect of local Coulomb interaction on Majorana corner modes: weak and strong correlation limits
S. V. Aksenov, A. D. Fedoseev, M. S. Shustin +1
Here we present an analysis of the evolution of Majorana corner modes realizing in a higher-order topological superconductor (HOTSC) on a square lattice under the influence of loca…
Topological superconductivity and Majorana states in low-dimensional systems
V. V. Val'kov, M. S. Shustin, S. V. Aksenov +4
We discuss the properties of topologically nontrivial superconducting phases and the conditions for their realization in condensed matter, and the principles for identifying Majora…

Strong Coulomb interactions in the problem of Majorana modes in a wire of the nontrivial topological class BDI
S. V. Aksenov, A. O. Zlotnikov, M. S. Shustin
In this study, the problem of strong Coulomb interactions in topological superconducting wire is analyzed by means of the density-matrix-renormalization-group (DMRG) approach. To a…
Stability of the coexistence phase of chiral superconductivity and noncollinear spin ordering with a nontrivial topology and strong electron correlations
Valery V. Val'kov, Anton O. Zlotnikov
We show that the quantum charge and spin fluctuations, while sufficiently renormalizing the magnetic order parameter, do not destroy the coexistence phase of chiral d+id supercondu…
The nontrivial ground state topology in the coexistence phase of chiral d-wave superconductivity and 120 degrees magnetic order on a triangular lattice
Valery V. Val'kov, Anton O. Zlotnikov, Maxim S. Shustin
The Z2 topological invariant is defined in the chiral d-wave superconductor having a triangular lattice in the presence of the 120 degrees magnetic ordering. By analyzing the Z2 in…
The influence of spin and charge fluctuations on the pressure dependence of the Neel temperature near a quantum phase transition in rare-earth intermetallic compounds
Valery V. Val'kov, Anton O. Zlotnikov
In the one-loop approximation for the periodic Anderson model the contributions of spin and charge fluctuations to the renormalization of the antiferromagnetic order parameter are…
