Orientational Ordering of Janus Particle Arrays as Classical Compass Spin Systems
Zhijie Fan, Myeonggon Park, Marija Vucelja +1
Janus-particle arrays provide a soft-matter platform in which particle orientations act as classical spins with anisotropic, bond-dependent interactions. Motivated by recent experi…
Cooperative Domain-Wall Dynamics in a Two-Dimensional Quasiclassical Holstein Model
Arunangshu Bora, Sankha Subhra Bakshi, Ho Jang +1
We investigate charge-density-wave (CDW) coarsening in a two-dimensional quasiclassical Holstein model following thermal quenches into the ordered phase. Although the staggered CDW…
Exact Equivariance from Ordinary Neural Networks for Lattice Many-Body Dynamics
Ho Jang, Sankha Subhra Bakshi, Gia-Wei Chern
Large-scale simulations of correlated electron systems require repeated evaluations of the electronic forces and transition energies driving collective dynamics. Machine-learning s…
Universality of the Magnetization Plateau and Quantum-Disordered States in the Kagome Family (; )
Prena Chaudhary, Asiri Thennakoon, Tommy Park +17
The microscopic origin of the low-field magnetization plateau in spin- kagome antiferromagnets remains unresolved. Here, we show that chemical pressure reshapes the hier…
Nonequilibrium Broken-Symmetry States from Retained Observables
Sankha Subhra Bakshi, Gia-Wei Chern
In equilibrium, broken-symmetry states are selected by the competition between energy and entropy. Out of equilibrium, slowly relaxing observables retain information about the prep…
Dynamical signatures of deconfined spinons in dimerized sawtooth chains
Nishan Ranabhat, Brandon B. Le, Seung-Hun Lee +1
We study the ground-state properties and dynamical response of the Heisenberg model on the sawtooth chain in and away from the exactly solvable valence-bond-solid (VBS) point. We e…
