Fano physics behind the N-resonance in graphene
R. O. Kuzian, D. V. Efremov, E. E. Krasovskii
Bound states and scattering resonances in the unoccupied continuum of a two-dimensional crystal predicted in [PhysRev B 87, 041405(R) (2013)] are considered within an exactly…
Doping dependence of low-energy charge collective excitations in high-T cuprates
V. M. Silkin, D. V. Efremov, M. Yu. Kagan
In this study, we analyze the dielectric function of high-Tc cuprates as a function of doping level, taking into account the full energy band dispersion within the CuO monolaye…
Breaking of Lorentz invariance caused by the interplay between spin-orbit interaction and transverse phonon modes in quantum wires
D. V. Efremov, Weyner Ccuiro, Luis E. F. Foa Torres +1
We investigate Lorentz invariance breaking in quantum wires due to Rashba spin-orbit interaction and transverse phonons. Using bosonization, we derive an effective action coupling…
Fate of density waves in the presence of a higher order van Hove singularity
Alkistis Zervou, Dmitriy V. Efremov, Joseph J. Betouras
Topological transitions in electronic band structures, resulting in van Hove singularities in the density of states, can considerably affect various types of orderings in quantum m…
