Strongly correlated metal interfaces in the Gutzwiller approximation
Giovanni Borghi, Michele Fabrizio, Erio Tosatti
We study the effect of spatial inhomogeneity on the physics of a strongly correlated electron system exhibiting a metallic phase and a Mott insulating phase, represented by the sim…
Kondo Conductance in an Atomic Nanocontact from First Principles
Procolo Lucignano, Riccardo Mazzarello, Alexander Smogunov +2
The electrical conductance of atomic metal contacts represents a powerful tool to detect nanomagnetism. Conductance reflects magnetism through anomalies at zero bias -- generally w…
AFM Dissipation Topography of Soliton Superstructures in Adsorbed Overlayers
Carlotta Negri, Nicola Manini, Andrea Vanossi +2
In the atomic force microscope, the nanoscale force topography of even complex surface superstructures is extracted by the changing vibration frequency of a scanning tip. An altern…
Tribology of the lubricant quantized-sliding state
Ivano Eligio Castelli, Rosario Capozza, Andrea Vanossi +3
In the framework of Langevin dynamics, we demonstrate clear evidence of the peculiar quantized sliding state, previously found in a simple 1D boundary lubricated model [Phys. Rev.…
Calculating Thermodynamics Properties of Quantum Systems by a non-Markovian Monte Carlo Procedure
Yanier Crespo, Alessandro Laio, Giuseppe E. Santoro +1
We present a history-dependent Monte Carlo scheme for the efficient calculation of the free-energy of quantum systems, inspired by the Wang-Landau sampling and metadynamics method.…
Connection Between Magnetism and Structure in Fe Double Chains on the Ir(100) Surface
R. Mazzarello, E. Tosatti
The magnetic ground state of nanosized systems such as Fe double chains, recently shown to form in the early stages of Fe deposition on Ir(100), is generally nontrivial. Using ab i…
