Neural Gauge-P Representation for Open Quantum Dynamics of Interacting Bosons
Xiaodong Cao, Zhicheng Zhong
Simulating the nonequilibrium dynamics of interacting open quantum systems remains challenging beyond small system sizes. Quantum phase-space representations provide a scalable app…
Dual instability of superconductivity from oxygen defects in LaNiO
Peiheng Jiang, Jie Li, Yu-Han Cao +4
We uncover a dual mechanism by which oxygen defects suppress superconductivity in the bilayer nickelate LaNiO using density functional theory, dynamical mean-field…
Neural network impurity solver for real-frequency dynamical mean-field theory
Fenglin Deng, Yi Lu, Xiaodong Cao +1
We introduce a neural network impurity solver for real-frequency DMFT that employs a multihead cross-attention mechanism to map hybridization functions to spectral functions, condi…
Quantum criticality and emergent orders in the spin-1 bilinear-biquadratic-Kitaev chain
Zhiling Wei, Zhengzhong Du, Xiaodong Cao +2
Higher-spin quantum magnets with competing interactions offer a rich platform for exploring quantum phases that transcend the paradigms of spin-1/2 systems, owing to their enlarged…
T-MSD: An improved method for ionic diffusion coefficient calculation from molecular dynamics
Yuxiang Gao, Xiaodong Cao, Zhicheng Zhong
Ionic conductivity is a critical property of solid ionic conductors, directly influencing the performance of energy storage devices such as batteries. However, accurately calculati…
Interlayer Hopping between Surface Mott Insulator and Bulk Band Insulator in layered 1T-TaS_{2}
Zijian Lin, Jie Li, Xiaodong Cao +7
In condensed matter physics, various mechanisms give rise to distinct insulating phases. The competition and interplay between these phases remain elusive, even for the seemingly m…
