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…
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…
The Interplay of Thermal Melting and Pump Driven Melting of Charge Order: A Two-Temperature Study of the Holstein Model
Debraj Bose, Sankha Subhra Bakshi, Pinaki Majumdar
Charge order driven by electron-phonon coupling is well understood at equilibrium but pump-probe experiments raise a new question: how does this order melt and recover after strong…
Exotic Spin Excitation Continuum in a Weakly Coupled Quantum Chainsaw Antiferromagnet
Asiri Thennakoon, Prena Chaudhary, Sankha Subhra Bakshi +9
Collective motions in strongly interacting magnets involve many spins and are often described in terms of integer-spin excitations. However, in certain cases, the collective motion…
Schwinger-Boson Mean-Field Study of the Anisotropic Kagome Antiferromagnet
Sankha Subhra Bakshi, Brandon B. Le, Seung-Hun Lee +1
We investigate the effect of spatial exchange anisotropy on the spin- kagome antiferromagnet using Schwinger-boson mean-field theory. The anisotropy is introduced by strengthe…
