Pseudospin Formulation of Quench Dynamics in the Semiclassical Holstein Model
Lingyu Yang, Ho Jang, Sankha Subhra Bakshi +2
We present a pseudospin formulation for the post-quench dynamics of charge-density-wave (CDW) order in the half-filled spinless Holstein model on a square lattice, assuming spatial…
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…
Thermal Quench Dynamics of Visons in Gapless Kitaev Spin Liquid
Yang Yang, Gia-Wei Chern
The relaxation dynamics of the Kitaev honeycomb model under a thermal quench is dominated by the quasi-stochastic diffusion and pair annihilation of visions, which are gapped flux…
Coarsening dynamics of Ising-nematic order in a frustrated Heisenberg antiferromagnet
Yang Yang, Yi-Hsuan Liu, Rafael M. Fernandes +1
We study the phase ordering dynamics of the classical antiferromagnetic - (nearest-neighbor and next-nearest-neighbor couplings) Heisenberg model on the square lattice in…
Enhanced coarsening of charge density waves induced by electron correlation: Machine-learning enabled large-scale dynamical simulations
Yang Yang, Chen Cheng, Yunhao Fan +1
The phase ordering kinetics of emergent orders in correlated electron systems is a fundamental topic in non-equilibrium physics, yet it remains largely unexplored. The intricate in…
