Representability-Aware Neural Networks for Reduced Density Matrices: Application to Fractional Chern Insulators
Justin B. Hart, Awwab A. Azam, Thomas Li +4
We develop a representability-aware and interpolable neural network (NN) framework for predicting two-particle reduced density matrices (2-RDMs). The NN incorporates a subset of re…
Realizing a tunable honeycomb lattice in ABBA-stacked twisted double bilayer WSe
Haining Pan, Eun-Ah Kim, Chao-Ming Jian
The ideal honeycomb lattice, featuring sublattice and SU(2) spin rotation symmetries, is a fundamental model for investigating quantum matters with topology and correlations. With…
Nematic excitonic insulator in transition metal dichalcogenide moiré heterobilayers
Ming Xie, Haining Pan, Fengcheng Wu +1
We study the effect of inter-electron Coulomb interactions on the displacement field induced topological phase transition in transition metal dichalcogenide (TMD) moiré heterobilay…
Topological Phases in AB-Stacked MoTe/WSe: Topological Insulators, Chern Insulators, and Topological Charge Density Waves
Haining Pan, Ming Xie, Fengcheng Wu +1
We present a theory on the quantum phase diagram of AB-stacked MoTe/WSe using a self-consistent Hartree-Fock calculation performed in the plane-wave basis, motivated by the…
Interaction range and temperature dependence of symmetry breaking in strongly correlated two-dimensional moiré transition metal dichalcogenide bilayers
Haining Pan, Sankar Das Sarma
We theoretically consider two-dimensional moiré transition metal dichalcogenide (TMD) bilayers, which are strongly correlated in the sense that the on-site Coulomb interaction is c…
Interaction-Driven Filling-Induced Metal-Insulator Transitions in 2D Moiré Lattices
Haining Pan, Sankar Das Sarma
Using a realistic band structure for twisted WSe materials, we develop a theory for the interaction-driven correlated insulators to conducting metals transitions through the t…
