Step-Edge Anomaly in Topological Metals
Oskar Schweizer, Virginia Gali, Adam Y. Chaou +3
Bulk-boundary correspondence guarantees the presence of robust, anomalous states on the boundary of topological matter. The edges of a two-dimensional Chern insulator harbor one-di…
Topological Gyromorphs
Laura Gómez Paz, Justin Schirmann, Adam Yanis Chaou +2
Gyromorphs are a new class of disordered systems that combine an amorphous-like absence of translational order with quasi-long-range rotational order. Gyromorphs can outperform qua…
Symmetric approximant formalism for statistical topological matter
R. Johanna Zijderveld, Adam Yanis Chaou, Isidora Araya Day +1
The standard approach to characterizing topological matter, computing topological invariants, fails when the symmetry protecting the topological phase is preserved only on average…
Magnetotransport across Weyl semimetal grain boundaries
Haoyang Tian, Vatsal Dwivedi, Adam Yanis Chaou +1
A clean interface between two Weyl semimetals features a universal, field-linear tunnel magnetoconductance of per magnetic flux quantum, where $N_\mathrm{ho}…
Proximity superconductivity in chiral kagome antiferromagnets
Adam Yanis Chaou, Gal Lemut, Felix von Oppen +1
Recent experiments on the chiral kagome antiferromagnet MnGe have provided strong evidence of proximity-induced spin-polarized superconductivity. We introduce and explore a min…
On the band topology of the breathing kagome lattice
Clara K. Geschner, Adam Yanis Chaou, Vatsal Dwivedi +1
A two-dimensional second-order topological insulator exhibits topologically protected zero-energy states at its corners. In the literature, the breathing kagome lattice with neares…
