Simple invariants for band topology
Adam Yanis Chaou, Adolfo G. Grushin, Peru d'Ornellas
Despite the exhaustive understanding gathered around non-interacting topological states of matter, there is no single method capable of systematically delivering simple, numericall…
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…
Disordered topological crystalline phases
Adam Yanis Chaou, Mateo Moreno-Gonzalez, Alexander Altland +1
The imposition of crystalline symmetries is known to lead to a rich variety of insulating and superconducting topological phases. These include higher-order topological phases and…
Quantum Oscillation Signatures of Fermi Arcs in Tunnel Magnetoconductance
Adam Yanis Chaou, Vatsal Dwivedi, Maxim Breitkreiz
Fermi-arc surface states of Weyl semimetals exhibit a unique combination of localization to a surface and connectivity to the bulk Weyl fermions that can move along the localizatio…
Magnetic Breakdown and Chiral Magnetic Effect at Weyl-Semimetal Tunnel Junctions
Adam Yanis Chaou, Vatsal Dwivedi, Maxim Breitkreiz
We investigate magnetotransport across an interface between two Weyl semimetals whose Weyl nodes project onto different interface momenta. Such an interface generically hosts Fermi…
Refining and relating fundamentals of functional theory
Julia Liebert, Adam Yanis Chaou, Christian Schilling
To advance the foundation of one-particle reduced density matrix functional theory (1RDMFT) we refine and relate some of its fundamental features and underlying concepts. We define…
Hinge States of Second-Order Topological Insulators as a Mach-Zehnder Interferometer
Adam Yanis Chaou, Piet W. Brouwer, Nicholas Sedlmayr
Three-dimensional higher-order topological insulators can have topologically protected chiral modes propagating on their hinges. Hinges with two co-propagating chiral modes can ser…
