No-Go Theorem and Routes towards Cavity-Enhanced Superconductivity
Qing-Dong Jiang
Recent experiments reporting cavity-vacuum-modified superconductivity raise a fundamental question: under what conditions can vacuum electromagnetic fluctuations increase a superco…
Multipolar Light-Matter Hamiltonians in Symmetry-Breaking Photonic Vacuums
Liu Yang, Jiadu Lin, Qing-Dong Jiang
We show that the conventional multipolar Hamiltonian is qualitatively modified when the photonic vacuum breaks inversion or time-reversal symmetry. By explicitly applying the Power…
Sound Induced Hall Currents in Weyl Exciton Insulators
Xinhong Zhou, Varsha Subramanyan, Qing-Dong Jiang
Weyl semimetals exhibit anomalous transport controlled by their gapless chiral nodes, while gapped Weyl systems are often expected to lose such distinctive responses. Here we show…
A field theory approach to Breit-type Hamiltonians in gapped Dirac systems
Xinhong Zhou, T. H. Hansson, Varsha Subramanyan +1
We develop a path-integral-based field theory for deriving Breit-type low-energy Hamiltonians for gapped Dirac systems coupled to both vector and axial gauge fields. Treating the m…
Quantum Hall Liquids Coupled to Dynamical Electromagnetism
T. H. Hansson, Qing-Dong Jiang, S. A. Kivelson +1
We investigate the effect on a Quantum Hall (QH) liquid of its coupling to 3+1 dimensional dynamical electromagnetism, which renders the system gapless. We calculate both the Hall…
