华为何庭波再次更新韬定律论文：那颗本该烧毁的“τ芯片”
一颗本最容易被“热”困住的堆叠芯片，为什么反倒能够做到更加省电？9月4日，华为半导体负责人何庭波再次在中科院科技论文预发布平台ChinaXiv发布论文《Huawei’s τ Chip Was Supposed to Melt?》，试图从芯片内部的数据传输和电路设计解释这一现象。
那颗本该烧毁的“τ芯片”，为什么反而跑得更冷了？
9月4日，华为半导体负责人何庭波再次在中国科学院科技论文预发布平台ChinaXiv上发布论文，标题很有意思——《Huawei‘s τ Chip Was Supposed to Melt?》（华为τ芯片本该烧毁？）。这不是她第一次发“韬定律”相关的论文了。
800V除了充电快，还有什么用
充5分钟的电就能跑100公里，里程焦虑都没有了。就和手机从5伏1安到现在的快充一样，800V的电车，就有点像是“超级快充手机”。
华为τ芯片为何越堆越省电
芯片越堆越密，按常理说应该更热，功耗也更高。可华为正在尝试证明另一种可能，芯片不只是靠把晶体管做小来进步，也可以通过重新安排电路，让数据少走一些路，最后实现更低功耗。9月4日，华为半导体负责人何庭波再次发布论文，继续解释τ芯片和LogicFolding技术。

Abstract:Pumps are transport mechanisms in which direct currents result from a cyclic evolution of the potential. As Thouless showed， the pumping process can have topological origins， when considering the motion of quantum particles in spatially and temporally periodic potentials. However， the periodic evolution that drives these pumps has always been assumed to be imparted from outside， as has been the case in the experimental systems studied so far. Here we report on an emergent mechanism for pumping in a quantum gas coupled to an optical resonator， where we observe a particle current without applying a periodic drive. The pumping potential experienced by the atoms is formed by the self-consistent cavity field interfering with the static laser field driving the atoms. Owing to dissipation， the cavity field evolves between its two quadratures， each corresponding to a different centrosymmetric crystal configuration. This self-oscillation results in a time-periodic potential analogous to that describing the transport of electrons in topological tight-binding models， such as the paradigmatic Rice–Mele pump. In the experiment， we directly follow the evolution by measuring the phase winding of the cavity field with respect to the driving field and observing the atomic motion in situ. The observed mechanism combines the dynamics of topological and open systems， and features characteristics of continuous dissipative time crystals.

华为τ芯片为何越堆越省电，关键不是“堆高”而是少走路
芯片越堆越密，按常识看应该更容易发热，可华为现在给出的答案却有些反直觉。9月4日，华为半导体负责人何庭波再次发布论文，继续解释τ芯片为什么没有被高密度结构拖进高功耗陷阱。这场讨论的核心，不只是芯片能不能做成三维结构，而是一个更基础的问题，芯片里的能量到底花在了哪里？
