A flat-band perspective on the boson peak in amorphous solids
Shivam Mahajan, Long-Zhou Huang, Cunyuan Jiang +4
The boson peak is a characteristic anomaly of amorphous solids broadly defined as a low-energy excess in the density of states and heat capacity compared to the textbook prediction…
Can we build a transistor using vacancy-induced bound states in a topological insulator
Cunyuan Jiang
Topological insulators (TIs) have been considered as promising candidates for next generation of electronic devices due to their topologically protected quantum transport phenomena…
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…
Topological signatures of collective dynamics and turbulent-like energy cascades in apolar active granular
Zihan Zheng, Cunyuan Jiang, Yangrui Chen +2
Active matter refers to a broad class of non-equilibrium systems where energy is continuously injected at the level of individual ``particles". These systems exhibit emergent colle…
The anomalous density of states and quasi-localized vibration through homogeneous thermalization of an inhomogeneous elastic system
Cunyuan Jiang
Amorphous solids are dynamically inhomogeneous due to in lack of translational symmetry and hence exhibit vibrational properties different from crystalline solids with anomalous lo…
