摘要：
共振超声光谱（RUS）是一种可在单次实验中测量给定材料完整弹性张量的强大技术。此前，该技术仅限于长方体、球体和圆柱体等规则形状的样品。我们展示了一种测定不规则形状样品弹性模量的新方法，将RUS的适用范围拓展至更多种类的材料。我们将这一新方法应用于新近发现的非常规超导体UTe₂，并给出了其在300开尔文和4开尔文下的弹性张量。
英文摘要：
Resonant ultrasound spectroscopy (RUS) is a powerful technique for measuring the full elastic tensor of a given material in a single experiment. Previously, this technique was limited to regularly-shaped samples such as rectangular parallelepipeds, spheres, and cylinders. We demonstrate a new method for determining the elastic moduli of irregularly-shaped samples, extending the applicability of RUS to a much larger set of materials. We apply this new approach to the recently-discovered unconventional superconductor UTe$_2$ and provide its elastic tensor at both 300 and 4 kelvin.
