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…
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…
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…
Revealing the Geometrical and Vibrational Properties of the Defects Driving the Boson Peak
Shivam Mahajan, Darryl Seow Yang Han, Cunyuan Jiang +2
In amorphous solids, the vibrational density of states shows an excess of modes over the Debye model, known as the boson peak, whose origin remains unclear. Studies suggest a link…
Shaping the topology of twisted bilayer graphene via time-reversal symmetry breaking
Cunyuan Jiang, Matteo Baggioli, Qing-Dong Jiang
Symmetry breaking is an effective tool for tuning the transport and topological properties of 2D layered materials. Among these materials, twisted bilayer graphene (TBG) has emerge…
A quantitative theoretical model of the boson peak based on stringlet excitations
Cunyuan Jiang, Matteo Baggioli, Jack F. Douglas
The boson peak (BP), a low-energy excess in the vibrational density of states over the phonon Debye contribution, is usually identified as one of the distinguishing features betwee…
