Anomalous coarsening and nonlinear diffusion of kinks in an one-dimensional quasi-classical Holstein model
Ho Jang, Yang Yang, Gia-Wei Chern
We study the phase-ordering dynamics of a quasi-classical Holstein model. At half-filling, the zero-temperature ground state is a commensurate charge-density-wave (CDW) with altern…

Kinetics of Peierls dimerization transition: Machine learning force-field approach
Ho Jang, Yang Yang, Gia-Wei Chern
We present a machine learning (ML) force-field framework for simulating the non-equilibrium dynamics of charge-density-wave (CDW) order driven by the Peierls instability. Since the…

Pattern formation in charge density wave states after a quantum quench
Lingyu Yang, Yang Yang, Gia-Wei Chern
We study post-quench dynamics of charge-density-wave (CDW) order in the square-lattice - model. The ground state of this system at half-filling is characterized by a checkerb…
