Extracting Chern numbers from the equilibrium transport noise of multiband bosons
Zhi-Wei Wang, Samuel L. Braunstein
We show that the equilibrium transport noise of a multiband bosonic system carries a measurable imprint of its Chern numbers, and we give the protocol that extracts them. For elect…
The modular energy range of an interval in chiral conformal field theory
Samuel L. Braunstein, Zhi-Wei Wang
We determine exactly the range of the modular Hamiltonian of an interval in a chiral conformal field theory over states of bounded energy. For an interval of length in a theory…
The Hodge structure of Berry-phase transport: topology, geometry, and noise
Zhi-Wei Wang, Samuel L. Braunstein
We show that the Hodge-de Rham decomposition of the Berry curvature organises the transport of a Bloch band and its fluctuations within a single geometric structure. Splitting the…
A sharp bound on spacetime distance from quantum entanglement
Zhi-Wei Wang, Arshid Shabir, Mir Faizal +1
Ryu-Takayanagi established how boundary entanglement encodes bulk area. We provide the metric counterpart: boundary mutual information imposes a rigorous lower bound on bulk geodes…
Lubkin-Page typicality bounds for Type~II von~Neumann factors
Zhi-Wei Wang, Samuel L. Braunstein
Typicality arguments for emergent spacetime rely on the Lubkin-Page bounds, which show that generic quantum states have vanishing correlations between subsystems. These bounds assu…
Hodge Topology of Semiclassical Transport: A Coordinate-Free Geometric Framework for the Anomalous Hall Effect and Non-Linear Berry Dipole
Zhi-Wei Wang, Samuel L. Braunstein
We establish a coordinate-free differential geometric framework for anomalous transport in topological bands using the Hodge-de Rham decomposition of the Brillouin zone. Standard f…
