We worked with the WASP laboratory and collaborators to map how bismuth boundary modes respond to a screw dislocation, placing the material close to a transition into a strong topological-insulator phase with nonzero weak indices. The work is published in Science Advances.
Raquel presented boundary-obstructed topological phases at the 2019 SPICE Young Research Leaders workshop in Mainz.
Raquel presented the real-space obstruction behind boundary-obstructed topological phases at the 2019 Simons Young Research Leaders meeting.
We worked with Tobias Holder and Ady Stern to connect Hall viscosity to the transverse electric field in narrow channels and to a viscous Hall angle in Corbino geometry. The work is published in Physical Review Letters.
We worked with Ady Stern to show that magnetic and superconducting proximity effects can spatially split a higher-order topological-insulator hinge mode into chiral electronic or Majorana channels. The work is published in Physical Review Letters.

Raquel gave a talk at the Relativistic Fermions and Nodal Semimetals from Topology program in Banff International Research Center, Canada.
Great meeting on Topological States of Matter at the International Institute of Physics, IIP, in Natal, Brazil.
In this recorded SPICE Young Research Leaders lecture, Raquel explains the topology of nodal superconductors and the experimental signatures that distinguish their protected states.
