Band geometry from position-momentum duality at topological band crossings
Yu-Ping Lin, Wei-Han Hsiao
We show that the position-momentum duality offers a transparent interpretation of the band geometry at the topological band crossings. Under this duality, the band geometry with Be…
Dual Haldane sphere and quantized band geometry in chiral multifold fermions
Yu-Ping Lin, Wei-Han Hsiao
We show that the chiral multifold fermions present a dual Haldane sphere problem in momentum space. Owing to the Berry monopole at the degenerate point, a dual Landau level emerges…
Time-reversal odd transport in bilayer graphene: Hall conductivity and Hall viscosity
Wei-Han Hsiao
We consider the time-reversal odd dynamics of the bilayer graphene at low energies in the quantum Hall regime. A generating functional for the effective action that captures the el…
Landau quantization of multilayer graphene on a Haldane sphere
Wei-Han Hsiao
We consider the problem of multilayer graphene on a Haldane sphere and determine the Landau level spectrum for this family of systems. This serves as a generalization of the Landau…
Self-Dual Bosonic Quantum Hall State in Mixed Dimensional QED
Wei-Han Hsiao, Dam Thanh Son
We consider a (2+1) dimensional Wilson-Fisher boson coupled to a (3+1) dimensional U(1) gauge field. This theory possesses a strong-weak duality in terms of the coupling constant e…
Duality and Universal Transport in a Mixed-Dimension Electrodynamics
Wei-Han Hsiao, Dam Thanh Son
We consider a theory of a two-component Dirac fermion localized on a (2+1) dimensional brane coupled to a (3+1) dimensional bulk. Using the fermionic particle-vortex duality, we sh…
