Corner Charge Fluctuations in Higher Dimensions
Xiao-Chuan Wu, Pok Man Tam, Xuyang Liang +4
Measuring charge fluctuations within a subregion provides a powerful probe of quantum many-body systems. In two spatial dimensions, the shape dependence of the dimensionless corner…
Fermi Surface Geometry from Charge Fluctuations in Three-Dimensional Metals
Pok Man Tam, Yarden Sheffer, Xiao-Chuan Wu +2
For three-dimensional non-interacting multi-band metals, we show that important information about the shape and the quantum geometry of Fermi surfaces is encoded in the subleading…
Singular three-point density correlations in two-dimensional Fermi liquids
Pok Man Tam, Charles L. Kane
We characterize a singularity in the equal-time three-point density correlations that is generic to two-dimensional interacting Fermi liquids. In momentum space where the three-poi…
When does a lattice higher-form symmetry flow to a topological higher-form symmetry at low energies?
Ruizhi Liu, Pok Man Tam, Ho Tat Lam +1
We study the lattice version of higher-form symmetries on tensor-product Hilbert spaces. Interestingly, at low energies, these symmetries may not flow to the topological higher-for…
Probing the Fermi Sea Topology in a Quantum Gas
Cyprien Daix, Pok Man Tam, Maxime Dixmerias +5
Pauli's exclusion principle forces fermions to occupy distinct quantum states, creating a filled region of momentum space at low temperature, the Fermi sea, whose topology governs…
Persistent Fluctuating Superconductivity and Planckian Dissipation in Fe(Te,Se)
Jonathan Stensberg, Pok Man Tam, Xiaoyu Yuan +11
Increasingly intricate phase diagrams in new classes of superconductors host fascinating interactions between superconductivity, diverse quantum phases, and quantum critical dynami…
