Signature of an Ultrafast Photo-Induced Lifshitz Transition in the Nodal-Line Semimetal ZrSiTe
Robert J. Kirby, Lukas Muechler, Sebastian Klemenz +6
Here we report an ultrafast optical spectroscopic study of the nodal-line semimetal ZrSiTe. Our measurements reveal that, converse to other compounds of the family, the sudden inje…
Influence of point defects on the electronic and topological properties of monolayer WTe
Lukas Muechler, Wei Hu, Chao Yang +2
In some topological insulators, such as graphene and WTe, band inversion originates from chemical bonding and space group symmetry, in contrast to materials such as BiSe$_3…
Superconducting order parameter of the nodal-line semimetal NaAlSi
Lukas Muechler, Zurab Guguchia, Jean-Christophe Orain +4
Nodal-line semimetals are topologically non-trivial states of matter featuring band crossings along a closed curve, i.e. nodal-line, in momentum space. Through a detailed analysis…
Modular Arithmetic with Nodal Lines: Drumhead Surface States in ZrSiTe
Lukas Muechler, Andreas Topp, Raquel Queiroz +5
We study the electronic structure of the nodal line semimetal ZrSiTe both experimentally and theoretically. We find two different surface states in ZrSiTe - topological drumhead su…
A topological classification of molecules and chemical reactions with a perplectic structure
Lukas Muechler
In this paper, a topological classification of molecules and their chemical reactions is proposed on a single particle level . We consider zero-dimensional electronic Hamiltonians…
Custodial glide symmetry of quantum spin Hall edge modes in WTe monolayer
Seulgi Ok, Lukas Muechler, Domenico Di Sante +3
A monolayer of WTe has been shown to display quantum spin Hall (QSH) edge modes persisting up to 100~K in transport experiments. Based on density-functional theory calculations…
