论文摘要
从生物凝胶到活组织的活性介质的机械响应受粘度和弹性之间的微妙相互作用的控制。在这封信中，我们将规范的开尔文 - Voigt和Maxwell模型推广到打破奇偶校验和时间反转对称性的主动粘弹性介质。所得的连续理论表现出粘性和弹性张量，这些粘性和弹性张量既是抗对称性或奇数，又是奇数。我们分析了这些违反粘弹性系数的这些平价如何确定奇数材料的弛豫机制和波传播特性。
The mechanical response of active media ranging from biological gels to living tissues is governed by a subtle interplay between viscosity and elasticity. In this Letter, we generalize the canonical Kelvin-Voigt and Maxwell models to active viscoelastic media that break both parity and time-reversal symmetries. The resulting continuum theories exhibit viscous and elastic tensors that are both antisymmetric, or odd, under exchange of pairs of indices. We analyze how these parity violating viscoelastic coefficients determine the relaxation mechanisms and wave-propagation properties of odd materials.
