Quantum criticality and nonequilibrium dynamics on a Lieb lattice of Rydberg atoms
Mark R. Hirsbrunner, Milan KornjaÄa, Rhine Samajdar +9
Neutral-atom quantum simulators offer a promising approach to the exploration of strongly interacting many-body systems, with applications spanning condensed matter, statistical me…
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…
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…
Quantized crystalline-electromagnetic responses in insulators
Sachin Vaidya, André Grossi Fonseca, Mark R. Hirsbrunner +2
We introduce new classes of gapped topological phases characterized by quantized crystalline-electromagnetic responses, termed "multipolar Chern insulators". These systems are char…
