Energetics of fractional anomalous Hall crystals in rhombohedral graphene
Félix Desrochers, Ashvin Vishwanath
Fractional anomalous Hall crystals (FAHCs) replicate the topological order of the fractional quantum Hall effect in the continuum without requiring any external magnetic field. The…
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…
Quantum Fisher Information as a Thermal Probe in Frustrated Magnets through Insights from Quantum Spin Ice
Chengkang Zhou, Zhengbang Zhou, Félix Desrochers +2
Quantum Fisher information (QFI) is a measure of multipartite entanglement accessible via inelastic neutron scattering. Here we demonstrate that QFI reveals thermal and dynamical p…
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…
Quantum Spin Liquids in Pyrochlore Magnets With Non-Kramers Local Moments
Tony An, Félix Desrochers, Yong Baek Kim
Numerous experiments on pyrochlore oxides Pr(Zr, Sn, Hf, Ir)O with non-Kramers Pr ions suggest that they support a quantum spin liquid (QSL) ground state, but th…
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…
Magnetic Field Response of Dipolar-Octupolar Quantum Spin Ice

Dipolar-octupolar (DO) pyrochlore systems Ce(Zr,Sn,Hf)O have garnered much attention as recent investigations suggest that they may stabilize a novel quantum spin ice (…
Emergent photons and fractionalized excitations in a quantum spin liquid
Bin Gao, Félix Desrochers, David W. Tam +6
A quantum spin liquid (QSL) arises from a highly entangled superposition of many degenerate classical ground states in a frustrated magnet, and is characterized by emergent gauge f…
Quantum Fluctuations Suppress the Critical Fields in BaCo(AsO)
Shiva Safari, William Bateman-Hemphill, Asimpunya Mitra +10
Early efforts to realize exotic quantum ground states in frustrated magnets focused on frustration arising from the lattice geometry alone. Attention has shifted to bond-dependent…
Finite Temperature Dynamics in 0-Flux and -Flux Quantum Spin Ice: Self-Consistent Exclusive Boson Approach
Félix Desrochers, Yong Baek Kim
Quantum spin ice (QSI) is an emblematic three-dimensional quantum spin liquid (QSL) on the pyrochlore lattice that hosts gapless photon-like modes and spinon excitations. De…
A pseudofermion functional renormalization group study of dipolar-octupolar pyrochlore magnets
