Direct calculation of the ionic mobility in superionic conductors
Alexandra Carvalho, Suchit Negi, Antonio Helio Castro Neto
We describe an approach based on non-equilibrium molecular dynamics (NEMD) simulations to calculate the ionic mobility of solid ion conductors such as solid electrolytes from first…
Microscopic theory of ionic motion in solids
Aleksandr Rodin, Keian Noori, Alexandra Carvalho +1
Drag and diffusion of mobile ions in solids are of interest for both purely theoretical and applied scientific communities. This article proposes a theoretical description of ion d…
Spin-Orbit Dirac Fermions in 2D Systems
Aleksandr S. Rodin, Paul Z. Hanakata, Alexandra Carvalho +3
We propose a novel model for including spin-orbit interactions in buckled two dimensional systems. Our results show that in such systems, intrinsic spin-orbit coupling leads to a f…
Electronic and plasmonic phenomena at graphene grain boundaries
Z. Fei, A. S. Rodin, W. Gannett +13
Graphene, a two-dimensional honeycomb lattice of carbon atoms, is of great interest in (opto)electronics and plasmonics and can be obtained by means of diverse fabrication techniqu…
Spatial Imaging of Landé g Factor through Extended Kondo Effect in a Single Magnetic Molecule
Liwei Liu, Yuhang Jiang, Boqun Song +7
A methodology of atomically resolved Landé g factor mapping of a single molecule is reported. Mn(II)-phthalocyanine (MnPc) molecules on Au(111) surface can be dehydrogenated via at…
Correlated magnetic states in domain and grain boundaries in graphene
Simone S. Alexandre, A. D. Lucio, A. H. Castro Neto +1
Ab initio calculations indicate that while the electronic states introduced by grain boundaries in graphene are only partially confined to the defect core, a domain boundary introd…
Electronic doping of graphene by deposited transition metal atoms
Jaime E. Santos, Nuno M. R. Peres, Joao M. B. Lopes dos Santos +1
We perform a phenomenological analysis of the problem of the electronic doping of a graphene sheet by deposited transition metal atoms, which aggregate in clusters. The sample is p…
Observation of the Kohn anomaly near the K point of bilayer graphene
D. L. Mafra, L. M. Malard, S. K. Doorn +4
The dispersion of electrons and phonons near the K point of bilayer graphene was investigated in a resonant Raman study using different laser excitation energies in the near infrar…
Adatoms in Graphene
Antonio H. Castro Neto, Valeri N. Kotov, Johan Nilsson +3
We review the problem of adatoms in graphene under two complementary points of view, scattering theory and strong correlations. We show that in both cases impurity atoms on the gra…
Fermi Liquid Theory of a Fermi Ring
T. Stauber, N. M. R. Peres, F. Guinea +1
We study the effect of electron-electron interactions in the electronic properties of a biased graphene bilayer. This system is a semiconductor with conduction and valence bands ch…
Metallic Continuum Quantum Ferromagnets at Finite Temperature
Antonio H. Castro Neto, Marcello B. Silva Neto
We study via renormalization group (RG) and large N methods the problem of continuum SU(N) quantum Heisenberg ferromagnets (QHF) coupled to gapless electrons. We establish the phas…
P-wave pairing and ferromagnetism in the metal-insulator transition in two dimensions
Claudio Chamon, Eduardo R. Mucciolo, Antonio H. Castro Neto
Based on recent experimental evidence for a spin polarized ground state in the insulating phase of the two-dimensional electron system, we propose that ferromagnetic spin fluctuati…
Non-Fermi Liquid Behavior in U and Ce Alloys: Criticality, Disorder, Dissipation, and Griffiths-McCoy singularities
Antonio H. Castro Neto, Barbara A. Jones
In this paper we provide the theoretical basis for the problem of Griffiths-McCoy singularities close to the quantum critical point for magnetic ordering in U and Ce intermetallics…
Superconducting phase coherence in striped cuprates
Antonio H. Castro Neto
We study the problem of phase coherence in doped striped cuprates. We assume the stripes to form a network of one-dimensional Luttinger liquids which are dominated by superconducti…
Doped planar quantum antiferromagnets with striped phases
A. H. Castro Neto, Daniel Hone
We study the properties of the striped phases that have been proposed for the doped cuprate planar quantum antiferromagnets. We invoke an effective, spatially anisotropic, non-line…
