A semi-Dirac Chern insulator model yields chiral edge states with cubic dispersion E(k) ∝ k³ instead of the usual linear form.
Nonlocal magic in fermionic Gaussian states is bounded by the entanglement spectrum of the covariance matrix, is extensive in the Haar ensemble, peaks at criticality in the Kitaev chain, and grows diffusively under random circuits.
Gauge fields induce a quantized transverse spin conductivity σ^{xy}=α² sgn(m) ℏ/4π in Dirac magnons of a honeycomb ferromagnet, with AC resonance at the topological gap, as a magnonic analog of the quantum Hall effect.
The renormalized fermionic Casimir energy between parallel plates is modified only by the normal component of the axial background vector b_z, which combines with the timelike b_0 into a single effective spectral parameter in a closed logarithmic integral representation.
A hetero-dimensional superconducting metamaterial with magnetic adatoms hosts a tunable weak-to-bulk-dissociated topological superconducting phase without requiring spin-orbit coupling.
A modified SSH model supports a pair of Jackiw-Rebbi zero modes that hybridize via tunneling, enabling coherent oscillations whose period is set by the hybridization gap.
Using bispherical coordinates and perturbative methods, the paper derives closed-form expressions for the magnetoelectric-induced magnetic fields around two interacting topological insulator spheres to leading order in the coupling constant.
Klein tunneling persists in a gapped Chern-insulator heterostructure due to Dirac mass inversion at the trivial-topological interfaces, producing explicit expressions for temperature-dependent linear and nonlinear conductances.

Transport of Dirac magnons driven by gauge fields
