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…
Ferromagnetic Kondo Effect at Nanocontacts
Paola Gentile, Lorenzo De Leo, Michele Fabrizio +1
Magnetic impurities bridging nanocontacts and break junctions of nearly magnetic metals may lead to permanent moments, analogous to the giant moments well known in the bulk case. A…
Surface dead layer for quasiparticles near a Mott transition
Giovanni Borghi, Michele Fabrizio, Erio Tosatti
Electron quasiparticles are progressively weakened by correlations upon approaching a continuos Mott metal insulator transition in a bulk solid. We show that corresponding to the b…
