Slow and Long-ranged Dynamical Heterogeneities in Dissipative Fluids
Karina E. Avila, Horacio E. Castillo, Katharina Vollmayr-Lee +1
A two-dimensional bidisperse granular fluid is shown to exhibit pronounced long-ranged dynamical heterogeneities as dynamical arrest is approached. Here we focus on the most direct…
Controlling energy landscapes with correlations between minima
Sai Teja Pusuluri, Alex Hunter Lang, Pankaj Mehta +1
Neural network models have been used to construct energy landscapes for modeling biological phenomena, in which the minima of the landscape correspond to memory patterns stored by…
Universal Scaling in the Aging of the Strong Glass Former SiO
Katharina Vollmayr-Lee, Christopher H. Gorman, Horacio E. Castillo
We show that the aging dynamics of a strong glass former displays a strikingly simple scaling behavior, connecting the average dynamics with its fluctuations, namely the dynamical…
Fluctuations in the Time Variable and Dynamical Heterogeneity in Glass-Forming Systems
Karina E. Avila, Horacio E. Castillo, Azita Parsaeian
We test a hypothesis for the origin of dynamical heterogeneity in slowly relaxing systems, namely that it emerges from soft (Goldstone) modes associated with a broken continuous sy…
Fluctuating Phases and Fluctuating Relaxation Times in Glass Forming Liquids
Gcina A. Mavimbela, Azita Parsaeian, Horacio E. Castillo
The presence of fluctuating local relaxation times, has been used for some time as a conceptual tool to describe dynamical heterogeneities in glass-forming systems. Howeve…
Time reparametrization invariance in arbitrary range p-spin models: symmetric versus non-symmetric dynamics
Gcina A. Mavimbela, Horacio E. Castillo
We explore the existence of time reparametrization symmetry in p-spin models. Using the Martin-Siggia-Rose generating functional, we analytically probe the long-time dynamics. We p…
