Multiple Photon Field-induced Topological States in Bulk HgTe
Dongbin Shin, I-Te Lu, Benshu Fan +6
Strong light-matter interactions can be exploited to modify properties of quantum materials both in and out of thermal equilibrium. Recent studies suggest electromagnetic fields in…
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…
Cavity engineering of solid-state materials without external driving
I-Te Lu, Dongbin Shin, Mark Kamper Svendsen +4
Confining electromagnetic fields inside an optical cavity can enhance the light-matter coupling between quantum materials embedded inside the cavity and the confined photon fields.…
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…
Combining experiments on luminescent centres in hexagonal boron nitride with the polaron model and ab initio methods towards the identification of their microscopic origin
Moritz Fischer, Ali Sajid, Jake Iles-Smith +10
The two-dimensional material hexagonal boron nitride (hBN) hosts luminescent centres with emission energies of 2 eV which exhibit pronounced phonon sidebands. We investigate the mi…
Indirect band gap semiconductors for thin-film photovoltaics: High-throughput calculation of phonon-assisted absorption
Jiban Kangsabanik, Mark Kamper Svendsen, Alireza Taghizadeh +2
Discovery of high-performance materials remains one of the most active areas in photovoltaics (PV) research. Indirect band gap materials form the largest part of the semiconductor…
as transparent top gate for near-field experiments
Niels C. H. Hesp, Mark Kamper Svendsen, Kenji Watanabe +4
Independent control of carrier density and out-of-plane displacement field is essential for accessing novel phenomena in two-dimensional material heterostructures. While this is ac…
Momentum-dependent oscillator strength crossover of excitons and plasmons in two-dimensional PtSe2
Jinhua Hong, Mark Kamper Svendsen, Masanori Koshino +4
The 1T-phase layered PtX2 chalcogenides has attracted widespread interest due to its thickness dependent metal-semiconductor transition driven by strong interlayer coupling. While…
Exploring and machine learning structural instabilities in 2D materials
Simone Manti, Mark Kamper Svendsen, Nikolaj R. Knøsgaard +2
We address the problem of predicting the zero-temperature dynamical stability (DS) of a periodic crystal without computing its full phonon band structure. Here we report the eviden…
Combining density functional theory with macroscopic QED for quantum light-matter interactions in 2D materials
Mark Kamper Svendsen, Yaniv Kurman, Peter Schmidt +3
A quantitative and predictive theory of quantum light-matter interactions in ultra thin materials involves several fundamental challenges. Any realistic model must simultaneously a…
Recent Progress of the Computational 2D Materials Database (C2DB)
M. N. Gjerding, A. Taghizadeh, A. Rasmussen +13
The C2DB is a highly curated open database organizing a wealth of computed properties for more than 4000 atomically thin two-dimensional (2D) materials. Here we report on new mater…
