Spectroscopic signatures of persistent exciton condensation in a bulk magnetic topological insulator
Paulina Majchrzak, Chakradhar Sahoo, Manuel Tuniz +7
Exciton condensates are long-sought correlated quantum states arising from macroscopic coherence of bound electron-hole pairs. Although equilibrium and transient excitonic states h…
Quantitative prediction of excitons in lattice-mismatched van der Waals heterostructures
Jakob Kjærulff Svaneborg, Mikkel Ohm Sauer, Amalie Helena Svaneborg +1
Accurate modeling of dielectric screening in van der Waals (vdW) heterostructures is essential for predicting photonic and optoelectronic properties - yet conventional first-princi…
Rigorous foundations of the effective mass approximation: analyticity and symmetry of band extrema
Jakob Kjærulff Svaneborg
The effective mass approximation is widely used across models of carrier transport, optical response, and excitons in semiconductors and insulators, but its validity hinges on the…
Bulk and surface electronic structure of MoAlB(010)
Gianmarco Gatti, Amalie H. Svaneborg, Wu Bing +11
The bulk and surface electronic structure of MoAlB(010) is studied by a combination of angle-resolved photoemission spectroscopy and density functional calculations. The observed b…
Self-consistent layer-projected scissors operator for band structures of complex 2D van der Waals materials
Dario A. Leon, Mikael Kuisma, Mikkel Ohm Sauer +6
We introduce a computationally efficient method to calculate the quasiparticle (QP) band structure of general van der Waals (vdW) heterostructures. A layer-projected scissors (LAPS…
Accurate Dielectric Response of Solids: Combining the Bethe-Salpeter Equation with the Random Phase Approximation
Amalie H. Søndersted, Mikael Kuisma, Jakob K. Svaneborg +2
The Bethe-Salpeter equation (BSE) can provide an accurate description of low-energy optical spectra of insulating crystals - even when excitonic effects are important. However, due…
Manipulation of magnetization and spin transport in hydrogenated graphene with THz pulses
Jakob Kjærulff Svaneborg, Aleksander Bach Lorentzen, Fei Gao +2
Terahertz (THz) field pulses can now be applied in Scanning Tunnelling Microscopy (THz-STM) junction experiments to study time resolved dynamics. The relatively slow pulse compared…
