Mobility-Gap Robustness and Středa-Hall Separation in Disordered Axion Pumping
Bryan Leung, Emil Prodan
We show that the noncommutative second Chern number of a D disordered axion pump remains quantized beyond global spectral gap closure at . Large-scale comp…
Classifying the Dynamics of Architected Materials by Groupoid Methods
Bram Mesland, Emil Prodan
We consider synthetic materials consisting of self-coupled identical resonators carrying classical internal degrees of freedom. The architecture of such material is specified by th…
Pumping with Symmetry
Julio Andrés Iglesias Martínez, Muamer Kadic, Vincent Laude +1
Re-configurable materials and meta-materials can jump between space symmetry classes during their deformations. Here, we introduce the concept of singular symmetry enhancement, whi…
Converging Periodic Boundary Conditions and Detection of Topological Gaps on Regular Hyperbolic Tessellations
Fabian R. Lux, Emil Prodan
Tessellations of the hyperbolic spaces by regular polygons are becoming popular because they support discrete quantum and classical models displaying unique spectral and topologica…
Smart patterning for topological pumping of elastic surface waves
Shaoyun Wang, Zhou Hu, Qian Wu +4
Topological pumping supplies a robust mechanism to steer waves across a sample without being affected by disorders and defects. For the first time, we demonstrate the pumping of el…
Cyclic cocycles and quantized pairings in materials science
Emil Prodan
The pairings between the cyclic cohomologies and the K-theories of separable -algebras supply topological invariants that often relate to physical response coefficients of…
