Tuning the topological insulator states of artificial graphene
H. D. Scammell, O. P. Sushkov
We develop a robust, non-perturbative approach to study the band structure of artificial graphene. Artificial graphene, as considered here, is generated by imposing a superlattice…
Nature of the spin liquid in underdoped cuprate superconductors
Y. A. Kharkov, O. P. Sushkov
In the present work we address a long standing problem of the magnetic ground state and magnetic excitations in underdoped cuprates. Modelling cuprates by the extended model…
Properties of the spin liquid phase in the vicinity of the Néel - Spin-Spiral Lifshitz transition in frustrated magnets
Yaroslav A. Kharkov, Jaan Oitmaa, Oleg P. Sushkov
Three decades ago Ioffe and Larkin pointed out a generic mechanism for the formation of a gapped spin liquid. In the case when a classical two-dimensional (2D) frustrated Heisenber…
Interference in spin-orbit coupled transverse magnetic focusing; emergent phase due to in-plane magnetic fields
Samuel S. R. Bladwell, Oleg P. Sushkov
Spin-orbit (SO) interactions in two dimensional systems split the Fermi surface, and allow for the spatial separation of spin-states via transverse magnetic focusing (TMF). In this…
