Negative thermal expansion in solid deuteromethane [PDF]
Low Temperature Physics, 2020 The thermal expansion at constant pressure of solid CD4 III is calculated for the low-temperature region where only the rotational tunneling modes are essential and the effect of phonons and librons can be neglected. It is found that in mK region there is a giant peak of the negative thermal expansion.

Isotropic Negative Thermal Expansion Metamaterials [PDF]
ACS Applied Materials & Interfaces, 2016 Negative thermal expansion materials are important and desirable in science and engineering applications. However, natural materials with isotropic negative thermal expansion are rare and usually unsatisfied in performance. Here, we propose a novel method to achieve negative thermal expansion via a metamaterial approach. The metamaterial is constructed
