Glass-like anomalies and unconventional thermoelectric transport in chimney ladder crystals
Srinivas V. Mandyam, Weicen Dong, Xiaoxian Yan +13
Nowotny chimney ladder (NCL) crystals present physical properties in between the contrasting paradigms of ideal crystal and amorphous solid, making them promising candidates for th…
Topological Magnetic Phases and Magnon-Phonon Hybridization in the Presence of Strong Dzyaloshinskii-Moriya Interaction
Weicen Dong, Haoxin Wang, Matteo Baggioli +1
In recent years, the interplay between quantum magnetism and topology has attracted growing interest, both for its fundamental importance and its technological potential. Topologic…
Designing atomic-scale resistive circuits in topological insulators through vacancy-induced localized modes
Cunyuan Jiang, Weicen Dong, Matteo Baggioli
We demonstrate that vacancies can induce topologically protected localized electronic excitations within the bulk of a topological insulator, and when sufficiently close, give rise…
Non-Hermitian wave-packet dynamics and its realization within a non-Hermitian chiral cavity
Weicen Dong, Qing-Dong Jiang, Matteo Baggioli
Topological wave-packet dynamics provide a powerful framework for studying quantum transport in topological materials. However, extending this approach to non-Hermitian quantum sys…
