Melting of 2D crystals is mediated by the dissociation of topological defects, which destroy the order of the crystal. In 2016, Michael Kosterlitz and David Thouless were awarded with the Nobel prize in physics for their idea, how thermally excited pairs of virtual dislocations induce a softening (described by renormalization group theory) of the crystal during heating. The shear elasticity disappears simultaneously with the dissociation of the dislocations, indicating a fluid phase. Bas… Web30 jul. 2024 · 在上世纪70年代初Mike Kosterlitz教授在物理学上最彷徨的时刻，他甚至无法在伯明翰大学找到合适的科研课题，直到他遇到David Thouless。 Thouless教授向Kosterlitz教授分享了PW Anderson和他的学生Gideon Yuval的一系列预印本论文，这打开了通往Kosterltiz-Thouless相变以及诺贝尔物理学奖的大门。
