Quantum Hall effect in a chiral cavity
Liu Yang, Gabriel Cardoso, Thors Hans Hansson +1
We investigate the influence of quantum fluctuations in a chiral cavity on the quantum Hall (QH) state, extending previous studies of QH liquids in linearly polarized cavities. Usi…
Cavity Quantum Hall Hydrodynamics
Gabriel Cardoso, Liu Yang, Thors Hans Hansson +1
Motivated by recent experiments, we study the coupling of quantum Hall (QH) hydrodynamics to quantum electrodynamics (QED) within a resonance cavity. In agreement with experimental…
Geometry Dynamics in Chiral Superfluids
Yuting Bai, Gabriel Cardoso, Rajae Malek +1
We investigate the geometric response of chiral superfluids when coupled to a dynamic background geometry. We find that geometry fluctuations, represented by the flexural mode, int…
Braids and Higher-order Exceptional Points from the Interplay Between Lossy Defects and Topological Boundary States
Zi-Jian Li, Gabriel Cardoso, Emil J. Bergholtz +1
We show that the perturbation of the Su-Schrieffer-Heeger chain by a localized lossy defect leads to higher-order exceptional points (HOEP). Depending on the location of the defect…
Geometry fluctuations in chiral superfluids
Gabriel Cardoso, Qing-Dong Jiang
The coupling of chiral superfluids and superconductors to the background geometry leads to surprising geometric induction phenomena. We show that this coupling bears important cons…
