Impulsive Fermi magnon-phonon resonance in antiferromagnetic
Thomas W. J. Metzger, Kirill A. Grishunin, Chris Reinhoffer +13
Understanding spin-lattice interactions in antiferromagnets is one of the most fundamental issues at the core of the recently emerging and booming fields of antiferromagnetic spint…
Observation of Kekulé vortices induced in graphene by hydrogen adatoms
Y. Guan, C. Dutreix, H. Gonzales-Herrero +5
Fractional charges are one of the wonders of the fractional quantum Hall effect, a liquid of strongly correlated electrons in a large magnetic field. Fractional excitations are als…
Nonlinear effects in the propagation of optically generated magnetostatic volume mode spin waves
L. J. A. van Tilburg, F. J. Buijnsters, A. Fasolino +2
Recent experimental work has demonstrated optical control of spin wave emission by tuning the shape of the optical pulse (Satoh et al.\ Nature Photonics, 6, 662 (2012)). We reprodu…
Chiral tunneling through generic one-dimensional potential barriers in bilayer graphene
V. Kleptsyn, A. Okunev, I. Schurov +2
We study tunneling of charge carriers in single- and bilayer graphene. We propose an explanation for non-zero "magic angles" with 100% transmission for the case of symmetric potent…
Transport and Optical Properties of Single- and Bilayer Black Phosphorus with Defects
Shengjun Yuan, A. N. Rudenko, M. I. Katsnelson
We study the electronic and optical properties of single- and bilayer black phosphorus with shortand long-range defects by using the tight-binding propagation method. Both types of…
Motion of domain walls and the dynamics of kinks in the magnetic Peierls potential
F. J. Buijnsters, A. Fasolino, M. I. Katsnelson
We study the dynamics of magnetic domain walls in the Peierls potential due to the discreteness of the crystal lattice. The propagation of a narrow domain wall (comparable to the l…
Phonons and electron-phonon coupling in graphene-h-BN heterostructures
Guus J. Slotman, Gilles A. de Wijs, Annalisa Fasolino +1
First principle calculations of the phonons of graphene-BN heterostructures are presented and compared to those of the constituents. We show that AA and AB' stacking are not only e…
Metal-Insulator Transition in Graphene on Boron Nitride
M. Titov, M. I. Katsnelson
Electrons in graphene aligned with hexagonal boron nitride are modelled by Dirac fermions in a correlated random-mass landscape subject to a scalar- and vector-potential disorder.…
Electronic Properties of Disordered Graphene Antidot Lattices
Shengjun Yuan, Rafael Roldán, Antti-Pekka Jauho +1
Regular nanoscale perforations in graphene (graphene antidot lattices, GAL) are known to lead to a gap in the energy spectrum, thereby paving a possible way towards many applicatio…
Spectral flow for Aharonov--Bohm rings generated by zero-mass lines
Timur Tudorovskiy, Vladimir E. Nazaikinskii, Mikhail I. Katsnelson
We found that the spectrum of the linear dispersion mode localized along the zero-mass line for variable mass Dirac fermions shows the nonzero spectral flow as a function of the ex…
Enhancement of the Curie temperature in small particles of weak itinerant ferromagnets
L. Peters, M. I. Katsnelson, A. Kirilyuk
Self consistent renormalization theory of itinerant ferromagnets is used to calculate the Curie temperature of clusters down to approximately 100 atoms in size. In these clusters t…
First-principles Theory of Nonlocal Screening in Graphene
M. van Schilfgaarde, M. I. Katsnelson
Using the quasiparticle self-consistent GW (QSGW) and local-density (LD) approximations, we calculate the q-dependent static dielectric function, and derive an effective 2D dielect…
The Effect of Cluster Formation on Graphene Mobility
K. M. McCreary, K. Pi, Adrian Swartz +6
We investigate the effect of gold (Au) atoms in the form of both point-like charged impurities and clusters on the transport properties of graphene. Cryogenic deposition (18 K) of…
Stable and fast semi-implicit integration of the stochastic Landau-Lifshitz equation
J. H. Mentink, M. V. Tretyakov, A. Fasolino +2
We propose new semi-implicit numerical methods for the integration of the stochastic Landau-Lifshitz equation with built-in angular momentum conservation. The performance of the pr…
Aharonov-Bohm effect in undoped graphene: Magnetotransport via evanescent waves
M. I. Katsnelson
Using conformal mapping technique, compact and general analytic expressions for the effects of magnetic fluxes on conductance and Fano factor of undoped graphene nanoflakes in pseu…
Conductance quantization in graphene nanoribbons: Adiabatic approximation
M. I. Katsnelson
A theory of electron states for graphene nanoribbons with a smoothly varying width is developed. It is demonstrated that the standard adiabatic approximation allowing to neglect th…
