标题： Emergent odd viscoelasticity in chiral soft glassy materials

摘要： 手性活性材料的流变性质在过去一段时间内一直是研究的重要领域，特别是在其机械响应中的奇数项方面。 尽管在奇数粘性流体和奇数弹性固体的研究中取得了很大进展，但对奇数粘弹性响应的理解仍然不足。 我们引入了一个手性软玻璃流变模型，以理解一类非晶固体中此类奇数粘弹性响应的出现和特性。 我们使用这个模型，该模型有效地考虑了玻璃基质中主动旋转的包含物的集合，来研究稳态和振荡剪切流下的线性应力响应。 对于稳态剪切，我们发现了一种奇数粘度，它非平凡地随着主动旋转频率{\Omega }的降低而增加。 在振荡剪切中，我们发现了一个奇数粘弹性谱，其对驱动频率{\omega }有非平凡的依赖关系，结合了在{\omega }= 2{\Omega }附近的共振效应以及在较大{\omega }处的玻璃状幂律。 显示英文摘要

摘要： Rheological properties of chiral active materials have been an important area of research in the recent past, in particular regarding odd terms in their mechanical response. While much progress has been made in the study of odd viscous fluids and odd elastic solids, there is still a lack of understanding of odd viscoelastic responses. We introduce a chiral soft glassy rheology model to understand the emergence and nature of such odd viscoelastic responses in a class of amorphous solids. We use this model, which effectively considers an ensemble of actively rotating inclusions in a glassy matrix, to study the linear stress response to steady and oscillatory shear flows. For steady shear we find an odd viscosity that, non-trivially, grows as the active rotation frequency {\Omega} decreases. In oscillatory shear we find an odd viscoelastic spectrum with a non-trivial dependence on the driving frequency {\omega}, combining resonance effects around {\omega} = 2{\Omega} with glassy power laws at larger {\omega}.
