Entangling many-body bound states with propagative modes in Bose-Hubbard systems
Mario Collura, Helge Aufderheide, Guillaume Roux +1
The quantum evolution of a cloud of bosons initially localized on part of a one dimensional optical lattice and suddenly subjected to a linear ramp is studied, realizing a quantum…
Mach-Zehnder Interferometric device for spin filtering in a GaAs/AlGaAs electron gas
Benjamin Santos, Ernesto Medina, Alexander López +1
A spin filtering device using quantum spin interference is theoretically proposed in a GaAs/AlGaAs electron gas that has both Rashba and Dresselhaus spin-orbit couplings. The devic…
Silicon intercalation into the graphene-SiC interface
F. Wang, K. Shepperd, J. Hicks +11
In this work we use LEEM, XPEEM and XPS to study how the excess Si at the graphene-vacuum interface reorders itself at high temperatures. We show that silicon deposited at room tem…
Asymmetric switching behavior in perpendicularly magnetized spin-valve nanopillars due to the polarizer dipole field
Daniel B. Gopman, Daniel Bedau, Stephane Mangin +4
We report the free layer switching field distributions of spin-valve nanopillars with perpendicular magnetization. While the distributions are consistent with a thermal activation…
Fe/MgO/Fe (100) textured tunnel junctions exhibiting spin polarization features of single crystal junctions
A. Duluard, B. Negulescu, C. Bellouard +8
Crystallographic and spin polarized transport properties of (100) textured and (100) epitaxial Fe/MgO/Fe magnetic tunnel junctions are compared. Strong similarities in the transpor…
Merging diabolical points of a superconducting circuit
Amélie Monjou, Raphaël Leone
We present the first theoretical study of the merging of diabolical points in the context of superconducting circuits. We begin by studying an analytically solvable four-level mode…
