Fundamental laws of chiral band crossings: local constraints, global constraints, and topological phase diagrams
Kirill Alpin, Moritz M. Hirschmann, Niclas Heinsdorf +4
We derive two fundamental laws of chiral band crossings: (i) a local constraint relating the Chern number to phase jumps of rotation eigenvalues; and (ii) a global constraint deter…
Symmetry-enforced topological band crossings in orthorhombic crystals: Classification and materials discovery
Andreas Leonhardt, Moritz M. Hirschmann, Niclas Heinsdorf +3
We identify all symmetry-enforced band crossings in nonmagnetic orthorhombic crystals with and without spin-orbit coupling and discuss their topological properties. We find that or…
Pulseshape discrimination against low-energy Ar-39 beta decays in liquid argon with 4.5 tonne-years of DEAP-3600 data
The DEAP Collaboration, P. Adhikari, R. Ajaj +126
The DEAP-3600 detector searches for the scintillation signal from dark matter particles scattering on a 3.3 tonne liquid argon target. The largest background comes from Ar b…
Symmetry-enforced band crossings in tetragonal materials: Dirac and Weyl degeneracies on points, lines, and planes
Moritz M. Hirschmann, Andreas Leonhardt, Berkay Kilic +2
We study the occurrence of symmetry-enforced topological band crossings in tetragonal crystals with strong spin-orbit coupling. By computing the momentum dependence of the symmetry…
Drumhead surface states and their signatures in quasiparticle scattering interference
Mehdi Biderang, Andreas Leonhardt, Nimisha Raghuvanshi +2
We consider a two-orbital tight-binding model defined on a layered three-dimensional hexagonal lattice to investigate the properties of topological nodal lines and their associated…
