Transport signatures of valley polarization in graphene multilayers: In-plane linear magnetoconductivity vs anomalous Hall effect
Fernando Peñaranda, Fernando de Juan
In two-dimensional materials where interacting Fermi pockets occur in valleys related by time-reversal symmetry, a spontaneous valley imbalance results in a novel state known as an…
Magnetic injection photocurrents in valley polarized states of twisted bilayer graphene
Fernando Peñaranda, Héctor Ochoa, Fernando de Juan
Magic-angle twisted bilayer graphene displays a complex phase diagram as a function of flat band filling, featuring compressibility cascade transitions and a variety of competing g…
Intrinsic and extrinsic photogalvanic effects in twisted bilayer graphene
Fernando Peñaranda, Hector Ochoa, Fernando de Juan
The chiral lattice structure of twisted bilayer graphene with D6 symmetry allows for intrinsic photogalvanic effects only at off-normal incidence, while additional extrinsic effect…
Phenomenology of Majorana zero modes in full-shell hybrid nanowires
Carlos Payá, Samuel D. Escribano, Andrea Vezzosi +4
Full-shell nanowires have been proposed as an alternative nanowire design in the search of topological superconductivity and Majorana zero modes (MZMs). They are hybrid nanostructu…
Supercurrent mediated by helical edge modes in bilayer graphene
Prasanna Rout, Nikos Papadopoulos, Fernando Peñaranda +5
Bilayer graphene encapsulated in tungsten diselenide can host a weak topological phase with pairs of helical edge states. The electrical tunability of this phase makes it an ideal…
Majorana bound states in encapsulated bilayer graphene
Fernando Peñaranda, Ramón Aguado, Elsa Prada +1
The search for robust topological superconductivity and Majorana bound states continues, exploring both one-dimensional (1D) systems such as semiconducting nanowires and two-dimens…
Flat bands in magic-angle vibrating plates
María Rosendo, Fernando Peñaranda, Johan Christensen +1
Twisted bilayer graphene develop quasi-flat bands at specific "magic" interlayer rotation angles through an unconventional mechanism connected to carrier chirality. Quasi-flat band…
Nontopological zero-bias peaks in full-shell nanowires induced by flux tunable Andreev states
Marco Valentini, Fernando Peñaranda, Andrea Hofmann +7
A semiconducting nanowire fully wrapped by a superconducting shell has been proposed as a platform for obtaining Majorana modes at small magnetic fields. In this study, we demonstr…
Even-odd effect and Majorana states in full-shell nanowires
Fernando Peñaranda, Ramón Aguado, Pablo San-Jose +1
Full-shell nanowires (semiconducting nanowires fully coated with a superconducting shell) have been recently presented as a novel means to create Majorana zero modes. In contrast t…
Quantifying wave-function overlaps in inhomogeneous Majorana nanowires
Fernando Peñaranda, Ramón Aguado, Pablo San-Jose +1
A key property of Majorana zero modes is their protection against local perturbations. In the standard picture, this protection is guaranteed by a high degree of spatial nonlocalit…
