Resolving support-mismatch by local basis rotation in variational Monte Carlo
Jia-Lin Chen, Zhen Fan, Canhui Yan +2
Real-time dynamics after a local quench by a charged operator encodes the response functions measured in spectroscopic experiments, yet they have long posed a challenge for variati…
Tree tensor network impurity solver based on Cayley-tree mapping
Bo Zhan, Jia-Lin Chen, Zhen Fan +1
We introduce a tree tensor network (TTN) impurity solver that enables highly efficient and accurate real-time simulations of quantum impurity models. By decomposing a noninteractin…
Hidden weak-pairing superconductivity of non-interacting anyons obeying statistics
Zheng-Duo Fan, Ashvin Vishwanath, Zijian Wang
We show that a non-interacting gas of charge- anyons with exchange statistics can superconduct through a hidden weak-pairing mechanism. Such an anyon gas arises nat…
Hessian-informed machine learning interatomic potential towards bridging theory and experiments
Bangchen Yin, Jian Ouyang, Zhen Fan +7
Local curvature of potential energy surfaces is critical for predicting certain experimental observables of molecules and materials from first principles, yet it remains far beyond…
On the Thermal Transport Puzzles in -RuCl
Zheng-Duo Fan, Xiao-Qi Sun, Jing-Yuan Chen
Thermal transport has been used to probe the nature of -RuCl, an important candidate of Kitaev material. Two remarkable observations were made under applied magnetic fields…
Minimal two band model and experimental proposals to distinguish pairing mechanisms of the high-T superconductor LaNiO
Zheng-Duo Fan, Ashvin Vishwanath
The discovery of high-T superconductivity in LaNiO has opened the door to a new route to high temperature superconductivity, distinct from that in cuprates and iron…
