Intrinsic mixed Bloch-Néel character and chirality switch of skyrmions in asymmetric epitaxial trilayer
Pablo Olleros-Rodríguez, Ruben Guerrero, Julio Camarero +2
Recent advances on the stabilization and manipulation of chiral magnetization configurations in systems consisting in alternating atomic layers of ferromagnetic and non-magnetic ma…
Axial anomaly generation by domain wall motion in Weyl semimetals
Julia D. Hannukainen, Yago Ferreiros, Alberto Cortijo +1
A space-time dependent node separation in Weyl semimetals acts as an axial vector field. Coupled with domain wall motion in magnetic Weyl semimetals, this induces axial electric an…
Piezoelectricity in monolayer hexagonal boron nitride
P. Ares, T. Cea, M. Holwill +7
Two-dimensional (2D) hexagonal boron nitride (hBN) is a wide-bandgap van der Waals crystal with a unique combination of properties, including exceptional strength, large oxidation…
Tailoring topological order and π-conjugation to engineer quasi-metallic polymers
B. Cirera, A. Sánchez-Grande, B. de la Torre +11
Topological band theory provides a conceptual framework to predict or even engineer robust metallic states at the boundaries of topologically distinct phases. The bulk-boundary cor…
A numerical study of the rippling instability driven by electron-phonon coupling in graphene
Tommaso Cea, Miguel Ruiz-Garcia, Luis Bonilla +1
Suspended graphene exhibits ripples of size ranging from 50 to 100 Å and height 10Å, however, their origin remains undetermined. Previous theoretical works have proposed that…
Attosecond timing of electron emission from a molecular shape resonance
S. Nandi, E. Plésiat, S. Zhong +11
Shape resonances in physics and chemistry arise from the spatial confinement of a particle by a potential barrier. In molecular photoionization, these barriers prevent the electron…
