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…
Dispersionless Flat Mode and Vibrational Anomaly in Active Brownian Vibrators Induced by String-like Dynamical Defects
Cunyuan Jiang, Zihan Zheng, Yangrui Chen +2
In recent years, active Brownian particles have emerged as a prominent model system for comprehending the behaviors of active matter, wherein particles demonstrate self-propelled m…
Phonons in stringlet-land and the boson peak
Cunyuan Jiang, Matteo Baggioli
Solid materials that deviate from the harmonic crystal paradigm exhibit characteristic anomalies in the specific heat and vibrational density of states (VDOS) with respect to Debye…
Experimental observation of gapped shear waves and liquid-like to gas-like dynamical crossover in active granular matter
Cunyuan Jiang, Zihan Zheng, Yangrui Chen +2
Unlike crystalline solids, liquids lack long-range order, resulting in diffusive shear fluctuations rather than propagating waves. Simulations predict that liquids exhibit a -ga…
