Narrowing of the flexural phonon spectral line in stressed crystalline two-dimensional materials
A. D. Kokovin, V. Yu. Kachorovskii, I. S. Burmistrov
We develop the microscopic theory for the attenuation of out-of-plane phonons in stressed flexible two-dimensional crystalline materials. We demonstrate that the presence of nonzer…
Emergent continuous symmetry in anisotropic flexible two-dimensional materials
I. S. Burmistrov, V. Yu. Kachorovskii, M. J. Klug +1
We develop the theory of anomalous elasticity in two-dimensional flexible materials with orthorhombic crystal symmetry. Remarkably, in the universal region, where characteristic le…
Coherent spin transport through helical edge states of topological insulator
R. A. Niyazov, D. N. Aristov, V. Yu. Kachorovskii
We study coherent spin transport through helical edge states of topological insulator tunnel-coupled to metallic leads. We demonstrate that unpolarized incoming electron beam acqui…
Differential Poisson's ratio of a crystalline two-dimensional membrane
I. S. Burmistrov, V. Yu. Kachorovskii, I. V. Gornyi +1
We compute the differential Poisson's ratio of a suspended two-dimensional crystalline membrane embedded into a space of large dimensionality . We demonstrate that, in the…
Nonmonotonic magnetoresistance of a two-dimensional viscous electron-hole fluid in a confined geometry
P. S. Alekseev, A. P. Dmitriev, I. V. Gornyi +3
Ultra-pure conductors may exhibit hydrodynamic transport where the collective motion of charge carriers resembles the flow of a viscous fluid. In a confined geometry (e.g., in ultr…
Magnetoresistance of compensated semimetals in confined geometries
P. S. Alekseev, A. P. Dmitriev, I. V. Gornyi +4
Two-component conductors -- e.g., semi-metals and narrow band semiconductors -- often exhibit unusually strong magnetoresistance in a wide temperature range. Suppression of the Hal…
