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…
Locally Repairable Convertible Codes: Improved Lower Bound and General Construction
Songping Ge, Han Cai, Xiaohu Tang
In this paper, we consider the convertible code with locally repairable property. We present an improved lower bound on access cost associated with . Then, we provide a gene…
MDS Generalized Convertible Code
Songping Ge, Han Cai, Xiaohu Tang
In this paper, we consider the convertible codes with the maximum distance separable (MDS) property, which can adjust the code rate according to the failure rates of devices. We fi…
