Exploring topology via momentum-selective tomography

Sainan Huai, Ling Lin, Kunliang Bu et al. · 2026

Identifying and measuring topological invariants remains a fundamental challenge due to the non-local nature of momentum eigenstates in real space. Established approaches based on Bloch oscillations, quantum walks, charge pumping and quench dynamics, typically fail to provide direct momentum-dependent geometric informa …

GFD-OPD: Guidance-Folded On-Policy Distillation of Diffusion Models Across Scales

Zhenxing Zhang, Jiayan Teng, Wenxu Wu et al. · 2026

On-policy distillation (OPD) has demonstrated two important capabilities in language models: compressing large teachers into smaller students and merging expert models into a single model. Existing diffusion OPD, however, mostly focus on the latter, with teachers and students sharing the same backbone and scale. We inv …
