Quantifying quasiparticle chirality in a chiral topological semimetal
Jiaju Wang, Jaime Sánchez-Barriga, Amit Kumar +17
Recently, the projection of the electron's spin on its crystal momentum has been proposed as a metric to quantify electronic chirality of Bloch states in crystals, which is expecte…
Monopole-like orbital-momentum locking and the induced orbital transport in topological chiral semimetals
Qun Yang, Jiewen Xiao, Iñigo Robredo +3
The interplay between chirality and topology nurtures many exotic electronic properties. For instance, topological chiral semimetals display multifold chiral fermions that manifest…
Unconventional charge-to-spin conversions in graphene/MoTe2 van der Waals heterostructures
Nerea Ontoso, C. K. Safeer, Franz Herling +9
Spin-charge interconversion (SCI) is a central phenomenon to the development of spintronic devices from materials with strong spin-orbit coupling (SOC). In the case of materials wi…
Parallel spin-momentum locking in a chiral topological semimetal
Jonas A. Krieger, Samuel Stolz, Inigo Robredo +23
Spin-momentum locking in solids describes a directional relationship between the electron's spin angular momentum and its linear momentum over the entire Fermi surface. While ortho…
Transport signatures of Fermi arcs at twin boundaries in Weyl materials
Sahal Kaushik, Iñigo Robredo, Nitish Mathur +4
One of the most striking signatures of Weyl fermions is their surface Fermi arcs. Less known is that Fermi arcs can also be localized at internal twin boundaries where two Weyl mat…
Spin-momentum locking from topological quantum chemistry: applications to multifold fermions
Mao Lin, Iñigo Robredo, Niels B. M. Schröter +3
In spin-orbit coupled crystals, symmetries can protect multifold degeneracies with large Chern numbers and Brillouin zone spanning topological surface states. In this work, we expl…
Cubic 3D Chern photonic insulators with orientable large Chern vectors
Chiara Devescovi, Mikel García-Díez, Iñigo Robredo +5
Time Reversal Symmetry (TRS) broken topological phases provide gapless surface states protected by topology, regardless of additional internal symmetries, spin or valley degrees of…
Cubic Hall viscosity in three-dimensional topological semimetals
Iñigo Robredo, Pranav Rao, Fernando de Juan +5
The nondissipative (Hall) viscosity is known to play an interesting role in two-dimensional (2D) topological states of matter, in the hydrodynamic regime of correlated materials, a…
Large multi-directional spin-to-charge conversion in low symmetry semimetal MoTe at room temperature
C. K. Safeer, Nerea Ontoso, Josep Ingla-Aynés +11
Efficient and versatile spin-to-charge current conversion is crucial for the development of spintronic applications, which strongly rely on the ability to electrically generate and…
Revisiting (higher order and crystalline) topology in old models of lead telluride
Iñigo Robredo, Maia G. Vergniory, Barry Bradlyn
In this work, we revisit the model of PbTe presented in [E. Fradkin, E. Dagotto, and D. Boyanovsky, Phys. Rev. Lett. 57, 2967 (1986)]. We show that the low energy theory of this mo…
