Ferromagnetic resonant tunneling diodes as spin polarimeters and polarizers

Francesco Giazotto, Fabio Taddei, Rosario Fazio +1

A method for measuring the degree of spin polarization of magnetic materials based on spin-dependent resonant tunneling is proposed. The device we consider is a ballistic double-ba…

Active suppression of dephasing in Josephson-junction qubits

Dmitri V. Averin, Rosario Fazio

Simple majority code correcting dephasing errors by encoding a qubit of information into physical qubits is studied quantitatively. We derive an equation for quasicontin…

Parity-dependent Kondo effect in ultrasmall metallic grains

Giancarlo Franzese, Roberto Raimondi, Rosario Fazio

We study the Kondo effect in an ultrasmall metallic grain, i.e. small enough to have a discrete energy-level spectrum, by calculating the susceptibility chi of the magnetic impurit…

Decoherence in a Cooper pair shuttle

Alessandro Romito, Francesco Plastina, Rosario Fazio

We examine decoherence effects in the Josephson current of a Cooper pair shuttle. Dephasing due to gate voltage fluctuations can either suppress or enhance the critical current and…

Shell structure in the density profiles for noninteracting fermions in anisotropic harmonic confinement

Patrizia Vignolo, Anna Minguzzi

We develop a Green's function method to evaluate the exact equilibrium particle-density profiles of noninteracting Fermi gases in external harmonic confinement in any spatial dimen…

Pair densities at contact in the quantum electron gas

R. Asgari, M. Polini, B. Davoudi +1

The value of the pair distribution function g(r) at contact (r = 0) in a quantum electron gas is determined by the scattering events between pairs of electrons with antiparallel sp…
