Localized states, topology and anomalous Hall conductivity on a 30 degrees twisted bilayer honeycomb lattice
Grigory Bednik
We consider twisted bilayer formed by two copies of Haldane model and explore its evolution with varying interlayer coupling strength. Specifically, we compute the sys…
Magnetothermopower of nodal line semimetals
Poulomi Chakraborty, Aaron Hui, Grigory Bednik +1
The search for materials with large thermopower is of great practical interest. Dirac and Weyl semimetals have recently proven to exhibit superior thermoelectric properties, partic…
Magnetic field induces giant nonlinear optical response in Weyl semimetals
Grigory Bednik, Vladyslav Kozii
We study the second-order optical response of Weyl semimetals in the presence of a magnetic field. We consider an idealized model of a perfectly linear Weyl node and use the Kubo f…
Theory of Moire Magnets and Topological Magnons: Applications to Twisted Bilayer CrI3
Kyoung-Min Kim, Do Hoon Kiem, Grigory Bednik +2
We develop a comprehensive theory of twisted bilayer magnetism. Starting from the first-principles calculations of two-dimensional honeycomb magnet CrI3, we construct the generic s…
Weyl hydrodynamics in a strong magnetic field
Siyu Zhu, Grigory Bednik, Sergey Syzranov
We study the hydrodynamic transport of electrons in a Weyl semimetal in a strong magnetic field. Impurity scattering in a Weyl semimetal with two Weyl nodes is strongly anisotropic…
Fluctuation-driven, topology-stabilized order in a correlated nodal semimetal
Nathan C. Drucker, Thanh Nguyen, Fei Han +19
The interplay between strong electron correlation and band topology is at the forefront of condensed matter research. As a direct consequence of correlation, magnetism enriches top…
