Collinear altermagnetism for 3D chiral higher-order topological insulators
Andreas Hadjipaschalis, Jennifer Cano
Despite significant progress in the study of higher-order topological insulators (HOTIs), the chiral -protected HOTI has remained elusive in electronic materials, w…
A unifying framework for sum rules and bounds on optical, thermoelectric and thermal transport from quantum geometry
M. Nabil Y. Lhachemi, Jennifer Cano
We present a geometric formulation of optical, thermoelectric, and thermal linear response in clean, zero temperature band insulators based on a single object: a generalized time-d…
Altermagnetism induced surface Chern insulator
Xuance Jiang, Sayed Ali Akbar Ghorashi, Deyu Lu +1
We propose a new pathway to the quantized anomalous Hall effect (QAHE) by coupling an altermagnet to a topological crystalline insulator (TCI). The former gaps the topological surf…
Majoranas with a twist: Tunable Majorana zero modes in altermagnetic heterostructures
Andreas Hadjipaschalis, Sayed Ali Akbar Ghorashi, Jennifer Cano
Altermagnetism provides new routes to realize Majorana zero modes with vanishing net magnetization. We consider a recently proposed heterostructure consisting of a semiconducting w…
Quantum-geometric dipole: a topological boost to flavor ferromagnetism in flat bands
Lei Chen, Sayed Ali Akbar Ghorashi, Jennifer Cano +1
Robust flavor-polarized phases are a striking hallmark of many flat-band moiré materials. In this work, we trace the origin of this spontaneous polarization to a lesser-known quant…
Tunable Topological Phases in Multilayer Graphene Coupled to a Chiral Cavity
Sayed Ali Akbar Ghorashi, Jennifer Cano, Ceren B. Dag
Coupling photonic cavity fields to electronic degrees of freedom in 2D materials introduces an additional control knob to the toolbox of solid-state engineering. Here we demonstrat…
