Geometry effects in topologically confined bilayer graphene loops
Nassima Benchtaber, David Sánchez, Llorenç Serra
We investigate the electronic confinement in bilayer graphene by topological loops of different shapes. These loops are created by lateral gates acting via gap inversion on the two…
Scattering of topological kink-antikink states in bilayer graphene structures
Nassima Benchtaber, David Sánchez, Llorenç Serra
Gapped bilayer graphene can support the presence of intragap states due to kink gate potentials applied to the graphene layers. Electrons in these states display valley-momentum lo…
Fluctuation-driven Coulomb drag in interacting quantum dot systems
Miguel A. Sierra, David Sánchez, Antti-Pekka Jauho +1
Coulomb drag between nanoscale conductors is of both fundamental and practical interest. Here, we theoretically study drag in a double quantum-dot (QD) system consisting of a biase…
Imaging the Thermal and Kinematic Sunyaev-Zel'dovich Effect Signals in a Sample of Ten Massive Galaxy Clusters: Constraints on Internal Velocity Structures and Bulk Velocities
Jack Sayers, Alfredo Montaña, Tony Mroczkowski +10
We have imaged the Sunyaev-Zel'dovich (SZ) effect signals at 140 and 270 GHz towards ten galaxy clusters with Bolocam and AzTEC/ASTE. We also used Planck data to constrain the sign…
Coulomb-blockade effect in nonlinear mesoscopic capacitors
M. I. Alomar, Jong Soo Lim, David Sánchez
We consider an interacting quantum dot working as a coherent source of single electrons. The dot is tunnel coupled to a reservoir and capacitively coupled to a gate terminal with a…
The Intrinsic Shape of Sagittarius A* at 3.5-mm Wavelength
Gisela N. Ortiz-León, Michael D. Johnson, Sheperd S. Doeleman +19
The radio emission from Sgr A is thought to be powered by accretion onto a supermassive black hole of at the Galactic Center. At millimete…
