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…
Quantum-geometric bounds on Casimir repulsion
Adolfo G. Grushin
The quantum geometric tensor has been shown to bound the gap, optical absorption, and dielectric susceptibilities of materials. Here we derive new quantum-geometric bounds on the m…
Leveraging structural disorder to enhance topological phases
Laura Gomez Paz, Peru d'Ornellas, Adolfo G Grushin
On-site disorder can be leveraged to induce a transition from a trivial to a topological insulator. However it is unclear if structural disorder in the absence of on-site disorder…
Non-Hermiticity-induced chirality imbalance of Weyl Landau levels
Sachin Vaidya, Alaa Bayazeed, André Grossi Fonseca +3
Weyl semimetals obey a global chirality constraint: the net chiral topological charge and any associated chiral spectral flow must vanish, as required by the Nielsen-Ninomiya theor…
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…
Topologically Protected Surface Altermagnetism on Antiferromagnets
Valentin Leeb, Peru d'Ornellas, Fernando de Juan +1
Altermagnetism (AM) and its associated spin-transport phenomena are typically linked to spin-split electronic band structures in bulk materials. However, the crystal surface has a…
