Mechanical exfoliation of non-van der Waals solids: a study of layered perovskite ferroelectric CsPb2Nb3O10 Open
Mechanical exfoliation of layered materials is one of the most effective methods for obtaining 2D nanosheets. However, this approach is still limited to van der Waals (vdW) layered materials, where interlayer interactions are governed by w…

Gas-liquid phase separation at zero temperature: mechanical interpretation and implications for gelation Open
The relationship between glasses and gels has been intensely debated for decades; however, the transition between these two phases remains elusive. To investigate a gel formation process in the zero-temperature limit and its relation to th…

Note: Quantitative approximation scheme of density of states near jamming Open
The vibrational density of states $D(\omega)$ plays a central role to characterize the low-temperature properties of solids. Here, we propose a simple yet accurate mean field like approximation to calculate $D(\omega)$ of harmonic spheres …

Vibrational density of states of jammed packing: mean-field theory and beyond. Open
Several mean-field theories predict that Hessian matrices of amorphous solids can be written by using the random matrix in the limit of the large spatial dimensions $d\to\infty$. Motivated by these results, we here propose a way to map a H…

Anomalous vibrational properties in the continuum limit of glasses Open
The low-temperature thermal properties of glasses are anomalous with respect to those of crystals. These thermal anomalies indicate that the low-frequency vibrational properties of glasses differ from those of crystals. Recent studies reve…
