Feature-energy duality of topological boundary states in a multilayer quantum spin Hall insulator
Physical review B, 2023Gapless topological boundary states characterize nontrivial topological phases arising from the bulk-boundary correspondence in symmetry-protected topological materials, such as the emergence of helical edge states in a two-dimensional $\mathbb{Z}_2 ...

Quantum anomalous valley Hall effect (QAVHE), which combines both the features of QAHE and AVHE, is both fundamentally intriguing and practically appealing, but is experimentally challenging to realize in two-dimensional (2D) intrinsic magnetic materials

Observation of a linked-loop quantum state in a topological magnet
Nature, 2021Quantum phases can be classified by topological invariants, which take on discrete values capturing global information about the quantum state1–13. Over the past decades, these invariants have come to play a central role in describing matter, providing ...

Quantum numbers and band topology of nanotubes
Journal of Physics A: Mathematical and General, 2003Summary: Nanotubes as well as polymers and quasi-1D subsystems of 3D crystals have line group symmetry. This allows two types of quantum numbers: roto-translational and helical. The roto-translational quantum numbers are linear and total angular (not conserved) momenta, while the helical quantum numbers are helical and complementary angular momenta ...

Topological Quantum Numbers in Nonrelativistic Physics
International Journal of Modern Physics B, 1997Voltage measurements using the ac Josephson effect and electrical resistance measurements using the quantum Hall effect are capable of very high precision, despite the relatively poor control of details of the devices. Such measurements rely on topological quantum numbers, which, unlike symmetry-based quantum numbers, are insensitive to deviations of ...

Scaling of the integrated quantum metric in disordered topological phases
Physical review BWe report a study of a disorder-dependent real-space representation of the quantum geometry in topological systems. Thanks to the development of an efficient linear-scaling numerical methodology based on the kernel polynomial method, we can explore ...

CONSERVATION OF TOPOLOGICAL QUANTUM NUMBERS IN ENERGY BANDS
Modern Physics Letters A, 1988Quantum systems described by parametrized Hamiltonians are studied in a general context. Within this context, the classification scheme of Avron-Seiler-Simon for non-degenerate energy bands is extended to cover general parameter spaces, while their sum rule is generalized to cover cases with degenerate bands as well.
