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…
Machine Learning Modeling of Charge-Density-Wave Recovery After Laser Melting
Sankha Subhra Bakshi, Yunhao Fan, Gia-Wei Chern
We investigate the nonequilibrium dynamics of a laser-pumped two-dimensional spinless Holstein model within a semiclassical framework, focusing on the melting and recovery of long-…
Emergent Spatial Textures from Interaction Quenches in the Hubbard Model
Sankha Subhra Bakshi, Gia-Wei Chern
Interaction quenches in strongly correlated electron systems provide a powerful route to probe nonequilibrium many-body dynamics. For the Hubbard model, nonequilibrium dynamical me…
Nonequilibrium DC Current Generation in a Driven Dissipative Haldane Model
Konrad Koenigsmann, Sankha Subhra Bakshi, Peter Schauss +1
The interplay of topology with nonequilibrium driving and dissipation in open quantum systems has recently attracted significant interest in condensed matter physics. In this work,…
