Three-stage melting of a macroscopic continuous spacetime crystal
Guoqing Liu, Jimin Bai, Matteo Baggioli +1
A spacetime crystal is a phase of matter that spontaneously develops periodic order in both space and time. Spacetime crystals have been experimentally observed in microscopic quan…

Tracking shear mode dynamics across the glass transition in a 2D colloidal system
Jimin Bai, Peter Keim, Matteo Baggioli
Long-wavelength collective shear dynamics are profoundly different in solids and liquids. According to the theoretical framework developed by Maxwell and Frenkel, collective shear…

Stress-stress correlations in two-dimensional amorphous and crystalline solids
Jimin Bai, Long-Zhou Huang, Jin Shang +3
Stress-stress correlations in crystalline solids with long-range order can be straightforwardly derived using elasticity theory. In contrast, the `emergent elasticity' of amorphous…
