Topological Landscape of Competing Charge Density Waves in $2H\text{−}{\mathrm{NbSe}}_{2}$

Topological Landscape of Competing Charge Density Waves in $2H\text{−}{\mathrm{NbSe}}_{2}$
Gyeongcheol Gye, Eunseok Oh, Han Woong Yeom
Despite decades of studies of the charge density wave (CDW) of $2H\text{−}{\mathrm{NbSe}}_{2}$, the origin of its incommensurate CDW ground state has not been understood. We discover that the CDW of $2H\text{−}{\mathrm{NbSe}}_{2}$ is composed of two different, energetically competing, structures. Th...
