A comprehensive study of the velocity, momentum and position matrix elements for Bloch states using a local orbital basis
J. J. Esteve-Paredes, J. J. Palacios
We present a comprehensive study of the velocity operator, , when used in crystalline solids calculations. The…
Isolation and characterization of few-layer black phosphorus
Andres Castellanos-Gomez, Leonardo Vicarelli, Elsa Prada +10
Isolation and characterization of mechanically exfoliated black phosphorus flakes with a thickness down to two single-layers is presented. A modification of the mechanical exfoliat…
Anomalous exchange interaction between intrinsic spins in conducting graphene systems
H. Santos, David Soriano, J. J. Palacios
We address the nature and possible observable consequences of singular one-electron states that appear when strong defects are introduced in the metallic family of graphene, namely…
Mechanical annealing of metallic electrodes at the atomic scale
C. Sabater, C. Untiedt, J. J. Palacios +1
The process of creating an atomically defined and robust metallic tip is described and quantified using measurements of contact conductance between gold electrodes and numerical si…
A critical analysis of vacancy-induced magnetism in mono and bilayer graphene
J. J. Palacios, F. Yndurain
The observation of intrinsic magnetic order in graphene and graphene-based materials relies on the formation of magnetic moments and a sufficiently strong mutual interaction. Vacan…
Fine Structure in Magnetization of Individual Fluxoid States
A. K. Geim, S. V. Dubonos, J. J. Palacios
Each time a vortex enters or exits a small superconductor, a different fluxoid state develops. We have observed splitting and sharp kinks on magnetization curves of such individual…
Metastability and paramagnetism in superconducting mesoscopic disks
J. J. Palacios
A projected order parameter is used to calculate, not only local minima of the Ginzburg-Landau energy functional, but also saddle points or energy barriers responsible for the meta…
Skyrme crystal or Skyrme liquid?
B. Paredes, J. J. Palacios
We address the quantum melting phase transition of the Skyrme crystal. Based on generic sum rules for two-dimensional, isotropic electron quantum liquids in the lowest Landau level…
Vortex matter in mesoscopic superconductors
J. J. Palacios
Superconducting mesoscopic devices in magnetic fields present novel properties which can only be accounted for by both the quantum confinement of the Cooper pairs and by the intera…
Magnons and skyrmions in fractional Hall ferromagnets
A. H. MacDonald, J. J. Palacios
Recent experiments have established a qualitative difference between the magnetization temperature-dependences of quantum Hall ferromagnets at integer and fractional filling…
Vortex lattices in strong type-II superconducting two-dimensional strips
J. J. Palacios
We show how to calculate semi-analytically the dense vortex state in strong type-II superconducting nanostructures. For the specific case of a strip, we find vortex lattice solutio…
Signature of Quantum Hall Effect Skyrmions in Tunneling: A Theoretical Study
J. J. Palacios, H. A. Fertig
We present a theoretical study of the tunneling characteristic between two parallel two-dimensional electron gases in a perpendicular magnetic field when both are near fillin…
Correlated few-electron states in vertical double-quantum-dot systems
Juan Jose Palacios, Pawel Hawrylak
The electronic properties of semiconductor, vertical, double quantum dot systems with few electrons are investigated by means of analytic, configuration-interaction, and mean-field…
Capacitance spectroscopy in quantum dots: Addition spectra and decrease of tunneling rates
J. J. Palacios, L. Martin-Moreno, G. Chiappe +2
A theoretical study of single electron capacitance spectroscopy in quantum dots is presented. Exact diagonalizations and the unrestricted Hartree-Fock approximation have been used…
