The influence of quantum geometry on the phase boundary and collective excitations of electron liquids and crystals
Paul Froese, Mark R. Hirsbrunner, Yong Baek Kim
Recent experiments on multilayer graphene systems have reinvigorated the study of electron crystallization, now with the inclusion of quantum geometry. In this work, we apply time-…
Chiral superconductors from parent states with nonuniform Berry curvature: Momentum-space vortices, Bogoliubov-de Gennes topology, and thermal Hall conductivity
L. David Le Nir, Asimpunya Mitra, Yong Baek Kim
We investigate chiral superconductivity emerging from parent electronic states with non-uniform Berry curvature, motivated by recent experiments in rhombohedral graphene multilayer…
Topological phonons in anomalous Hall crystals
Mark R. Hirsbrunner, Félix Desrochers, Joe Huxford +1
Recent experiments on few-layer graphene structures have reported indirect signatures of anomalous Hall crystals (AHCs), but the need for a top gate to stabilize the phase preclude…
Electronic Crystal Phases in the Presence of Non-Uniform Berry Curvature and Tunable Berry Flux: The -Jellium model
Félix Desrochers, Joe Huxford, Mark R. Hirsbrunner +1
Recent experiments on multilayer graphene systems have rekindled interest in electronic crystal phases in two dimensions -- but now for phases enriched by non-trivial quantum geome…
Probing quantum geometry with two-dimensional nonlinear optical spectroscopy
Paul Froese, Mark R. Hirsbrunner, Yong Baek Kim
Recent studies have shown that the nonlinear optical response of crystalline systems is fundamentally a quantum geometric property. In this work, we propose two-dimensional coheren…
Dynamics and lifetime of geometric excitations in moiré systems
Yuzhu Wang, Joe Huxford, Dung Xuan Nguyen +3
We show that spin-2 geometric excitations, known as graviton modes, generally exhibit vanishing lifetimes in lattice Chern bands, including in moiré systems. In contrast to the Lan…
Elastic Response and Instabilities of Anomalous Hall Crystals
Félix Desrochers, Mark R. Hirsbrunner, Joe Huxford +3
Anomalous Hall crystals (AHCs) are exotic phases of matter that simultaneously break continuous translation symmetry and exhibit the quantum anomalous Hall effect. AHCs have recent…
