Valley-resolved high harmonics probe symmetry breaking beyond the Dirac cone
Pablo Pais, Alfredo Iorio, Marcelo F. Ciappina
Low-energy electrons in graphene obey an emergent, rotationally invariant Dirac equation, while the honeycomb lattice enters only through higher-order, symmetry-breaking correction…

Convertible Polynomial Evaluation Codes in the Merge Regime: A Skew-Polynomial Framework
Songping Ge, Han Cai, Xiaohu Tang
In this paper, we develop an algebraic framework for merge-regime convertible codes that works directly with the polynomial-evaluation structure of the underlying codes. We charact…

Convertible Codes: MSR-to-MSR Conversion with Optimal Access and Bandwidth
Yumeng Yang, Han Cai, Xianfu Lei +1
In this paper, we study convertible codes in the merge regime and focus on the minimum storage regenerating (MSR) setting, where both the initial codes and the final code admit opt…
