Physical rendering of synthetic spaces for topological sound transport
Hui Chen, Hongkuan Zhang, Qian Wu +5
Synthetic dimensions can be rendered in the physical space and this has been achieved with photonics and cold atomic gases, however, little to no work has been succeeded in acousti…
Revealing the boundary Weyl physics of the four-dimensional Hall effect via phason engineering in metamaterials
Wenting Cheng, Emil Prodan, Camelia Prodan
Quantum Hall physics has been theoretically predicted in 4-dimensions and higher. In hypothetical 2n-dimensions, the topological characters of both the bulk and the boundary are ma…
Mapping Chern numbers in quasi-periodic interacting spin chains
Yifei Liu, Emil Prodan
Quasi-periodic quantum spin chains were recently found to support many topological phases in the finite magnetization sectors. They can simulate strong topological phases from clas…
Disordered Crystals from First Principles II: Transport Coefficients
Thomas D. Kühne, Julian Heske, Emil Prodan
This is the second part of a project on the foundations of first-principle calculations of the electron transport in crystals at finite temperatures, aiming at a predictive first-p…
Experimental Demonstration of Dynamic Topological Pumping Across Incommensurate Bilayered Acoustic Metamaterials
Wenting Cheng, Emil Prodan, Camelia Prodan
A Thouless pump can be regarded as a dynamical version of the integer quantum Hall effect. In a finite-size configuration, such topological pump displays edge modes that emerge dyn…
A Computer Code for Topological Quantum Spin Systems over Triangulated Surfaces
Yingkai Liu, Emil Prodan
We derive explicit closed-form matrix representations of Hamiltonians drawn from tensored algebras, such as quantum spin Hamiltonians. These formulas enable us to soft-code generic…
