RFPO: Rectified Flow Policy Optimization for Embodied Control

Ting Huang, Lisiyu Pan, Haoyu Wang +6

Flow-based policies provide an expressive framework for continuous robot control, but their iterative ODE integration incurs substantial inference cost. Naively reducing the integr…

Strong Dimerization and Field-Induced Reconstruction of the Low-Energy Spectrum in $Cu_{3} (OH)_{4} (HCO_{2})_{2}$

Sk Saniur Rahaman, S. R. Hassan

We investigate the field-dependent low-energy thermodynamics of the distorted triangular quantum antiferromagnet $Cu_{3} (OH)_{4} (HCO_{2})_{2}$ using a sector-res…

Covariance Geometry of Basis-Resolved Low-Energy Wavefunctions in the Spin- $1/2$ Kitaev--Heisenberg Model

Sk Saniur Rahaman, S. R. Hassan

We develop a basis-resolved covariance framework for investigating the organization of low-energy many-body wavefunctions in the spin- $1/2$ Kitaev--Heisenberg model. By constructin…
