Dynamic heterogeneity in sodium silicate melts via machine-learning potential
Kumpei Shiraishi, Rikuta Nozawa, Emi Minamitani
We present a comprehensive characterisation of dynamic heterogeneity in sodium silicate melts using molecular dynamics simulation with machine-learning potentials. By studying sodi…
Topological descriptor for interpretable thermal transport prediction in amorphous graphene
Kosuke Yamazaki, Takuma Shiga, Kumpei Shiraishi +1
Understanding and predicting thermal transport in disordered materials remains a significant challenge due to the absence of periodicity and the complex nature of medium-range stru…
Critical fluctuations of elastic moduli in jammed solids
Kumpei Shiraishi, Hideyuki Mizuno
We investigate sample-to-sample fluctuations of the shear modulus in ensembles of particle packings near the jamming transition. Unlike the average modulus, which exhibits distinct…
Benchmarking thermostat algorithms in molecular dynamics simulations of a binary Lennard-Jones glass-former model
Kumpei Shiraishi, Emi Minamitani, Kang Kim
A systematic comparison was carried out to assess the influence of representative thermostat methods in constant-temperature molecular dynamics simulations. The thermostat schemes…
Characterising the slow dynamics of the swap Monte Carlo algorithm
Kumpei Shiraishi, Ludovic Berthier
The swap Monte Carlo algorithm introduces non-physical dynamic rules to accelerate the exploration of the configuration space of supercooled liquids. Its success raises deep questi…
Particle pinning as a method to manipulate marginal stability
Kumpei Shiraishi, Yusuke Hara
We study the critical behavior of low-frequency vibrations of packings with pinned particles near the jamming point. Soft modes form a plateau in the density of states and its freq…
