DREAM: Efficient Dataset Distillation by Representative Matching

Kavli Affiliate: Zheng Zhu | First 5 Authors: Yanqing Liu, Jianyang Gu, Kai Wang, Zheng Zhu, Wei Jiang | Summary: Dataset distillation aims to synthesize small datasets with little information loss from original large-scale ones for reducing storage and training costs. Recent state-of-the-art methods mainly constrain the sample synthesis process by matching synthetic images and […]

Inverse-current quantum electro-oscillations in a charge-density wave insulator

Kavli Affiliate: Yi Zhou | First 5 Authors: Tian Le, Ruiyang Jiang, Linfeng Tu, Renji Bian, Yiwen Ma | Summary: Quantum magneto-oscillations have long been a vital subject in condensed matter physics, with ubiquitous quantum phenomena and diverse underlying physical mechanisms. Here, we demonstrate the intrinsic and reproducible DC-current-driven quantum electro-oscillations with a periodicity in […]

Analytical theory of cat scars with discrete time crystalline dynamics in Floquet systems

Kavli Affiliate: Biao Huang | First 5 Authors: Biao Huang, , , , | Summary: We reconstruct the spectral pairing (SP) theories to enable analytical descriptions of eigenstate spatiotemporal orders in translation-invariant systems without prethermal conditions. It is shown that the strong Ising interactions and drivings alone stabilize a class of “cat scar" eigenstates with […]

Chiral spin liquid in a $mathbb{Z}_3$ Kitaev model

Kavli Affiliate: Cheng Peng | First 5 Authors: Li-Mei Chen, Tyler D. Ellison, Meng Cheng, Peng Ye, Ji-Yao Chen | Summary: We study a $mathbb{Z}_3$ Kitaev model on the honeycomb lattice with nearest neighbor interactions. Based on matrix product state simulations and symmetry considerations, we find evidence that, with ferromagnetic isotropic couplings, the model realizes […]

Variational Tensor Wavefunctions for the Interacting Quantum Spin Hall Phase

Kavli Affiliate: Shenghan Jiang | First 5 Authors: Yixin Ma, Shenghan Jiang, Chao Xu, , | Summary: The quantum spin hall (QSH) phase, also known as the two-dimensional topological insulator, hosts helical edge modes protected by time-reversal symmetry. While first proposed as a band insulator, this phase can also be realized in strongly-correlated systems, where […]
