Temperature effects in topological insulators of transition metal dichalcogenide monolayers
Siyu Chen, Isaac J. Parker, Bartomeu Monserrat
We investigate the role of temperature on the topological insulating state of metal dichalcogenide monolayers, 1T-MX (M=W, Mo and X=S, Se). Using first principles calc…
Photo-induced electronic and spin topological phase transitions in monolayer bismuth
Bo Peng, Gunnar F. Lange, Daniel Bennett +3
Ultrathin bismuth exhibits rich physics including strong spin-orbit coupling, ferroelectricity, nontrivial topology, and light-induced structural dynamics. We use \textit{ab initio…
On the dynamical stability of copper-doped lead apatite
Sun-Woo Kim, Kang Wang, Siyu Chen +5
The recent claim of room temperature superconductivity in a copper-doped lead apatite compound, called LK-99, has sparked remarkable interest and controversy. Subsequent experiment…
High-chirality and multiquaternion Weyl nodes in hexagonal ReO
Siyu Chen, Robert-Jan Slager, Bartomeu Monserrat +1
The formation of two-band nodal points in gapless topological phases, referred to as conventional Weyl nodes, relies solely on translational symmetry. However, when coupled with ot…
Negative refraction of Weyl phonons at twin quartz interfaces
Juan D. F. Pottecher, Gunnar F. Lange, Cameron Robey +2
In nature, -quartz crystals frequently form contact twins - two adjacent crystals with the same chemical structure but different crystallographic orientation, sharing a common l…
Microscopic theory of colour in lutetium hydride
Sun-Woo Kim, Lewis J. Conway, Chris J. Pickard +2
Nitrogen-doped lutetium hydride has recently been proposed as a near-ambient-conditions superconductor. Interestingly, the sample transforms from blue to pink to red as a function…
Excitonic Insulator to Superconductor Phase Transition in Ultra-Compressed Helium
Cong Liu, Ion Errea, Chris Pickard +8
Helium, the second most abundant element in the universe, exhibits an extremely large electronic band gap of about eV at low pressures ( GPa). While the metallization…
