Extended Hubbard model on fractals: d-Wave superconductivity and competing pairing channels
Robert Canyellas, Mikhail I. Katsnelson, Andrey Bagrov
Fractal structures such as the Sierpiński gasket have been predicted to enhance the critical temperature of s-wave superconductivity compared to regular crystals while maintaining…
Stress-controlled Poisson ratio of a crystalline membrane: Application to graphene
I. S. Burmistrov, I. V. Gornyi V. Yu. Kachorovskii, M. I. Katsnelson +2
We demonstrate that a key elastic parameter of a suspended crystalline membrane---the Poisson ratio (PR) ---is a non-trivial function of the applied stress and of the system…
Quantum elasticity of graphene: Thermal expansion coefficient and specific heat
I. S. Burmistrov, I. V. Gornyi, V. Yu. Kachorovskii +2
We explore thermodynamics of a quantum membrane, with a particular application to suspended graphene membrane and with a particular focus on the thermal expansion coefficient. We s…
Giant magneto-drag in graphene at charge neutrality
M. Titov, R. V. Gorbachev, B. N. Narozhny +9
We report experimental data and theoretical analysis of Coulomb drag between two closely positioned graphene monolayers in weak magnetic field. Close enough to the neutrality point…
Quantized coexisting electrons and holes in graphene measured using temperature dependent magneto-transport
E. V. Kurganova, S. Wiedmann, A. J. M. Giesbers +6
We present temperature-dependent magneto-transport experiments around the charge neutrality point in graphene and determine the amplitude of potential fluctuations responsible…
A new route towards uniformly functionalized single-layer graphene
D. W. Boukhvalov, M. I. Katsnelson
It is shown, by DFT calculations, that the uniform functionalization of upper layer of graphite by hydrogen or fluorine does not change essentially its bonding energy with the unde…
