Hexagonal-to-base-centered-orthorhombic $4 Q$ charge density wave order in kagome metals KV $_{3}$ Sb $_{5}$ , RbV $_{3}$ Sb $_{5}$ , and CsV $_{3}$ Sb $_{5}$

Alaska Subedi

I search for the ground state structures of the kagome metals KV $_{3}$ Sb $_{5}$ , RbV $_{3}$ Sb $_{5}$ , and CsV $_{3}$ Sb $_{5}$ using first principles calculations. Group-theoretical analysis shows t…

Trigonal-to-monoclinic structural transition in TiSe $_{2}$ due to a combined condensation of $q = (\frac{1}{2}, 0, 0)$ and $(\frac{1}{2}, 0, \frac{1}{2})$ phonon instabilities

Alaska Subedi

I present first principles calculations of the phonon dispersions of TiSe $_{2}$ in the $P 3 c 1$ phase, which is the currently accepted low-temperature structure of this mate…
