Electrostatic tuning of bilayer graphene edge modes
Hira Ali, Llorenç Serra
We study the effect of a local potential shift induced by a side electrode on the edge modes at the boundary between gapped and ungapped bilayer graphene. A potential shift close t…
Conductance asymmetry in proximitized magnetic topological insulator junctions with Majorana modes
Daniele Di Miceli, Eduárd Zsurka, Julian Legendre +3
We theoretically discuss electronic transport via Majorana states in magnetic topological insulator-superconductor junctions with an asymmetric split of the applied bias voltage. W…
Conductance of electrostatic wire junctions in bilayer graphene
Sungguen Ryu, Rosa López, Llorenç Serra
The conductance of electrostatic wire junctions in bilayer graphene, classified as trivial-trivial or trivial-topological regarding the confinement character on each junction side,…
Trivial and topological bound states in bilayer graphene quantum dots and rings
Nassima Benchtaber, David Sánchez, Llorenç Serra
We discuss and compare two different types of confinement in bilayer graphene by top and bottom gating with symmetrical microelectrodes. Trivial confinement corresponds to the same…
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…
Beating Carnot efficiency with periodically driven chiral conductors
Sungguen Ryu, Rosa López, Llorenç Serra +1
Classically, the power generated by an ideal thermal machine cannot be larger than the Carnot limit. This profound result is rooted in the second law of thermodynamics. A hot quest…
