Brightening of a dark monolayer semiconductor via strong light-matter coupling in a cavity
Hangyong Shan, Ivan Iorsh, Bo Han +13
Engineering the properties of quantum materials via strong light-matter coupling is a compelling research direction with a multiplicity of modern applications. Those range from mod…
Spatial coherence of room-temperature monolayer WSe exciton-polaritons in a trap
Hangyong Shan, Lukas Lackner, Bo Han +16
The emergence of spatial and temporal coherence of light emitted from solid-state systems is a fundamental phenomenon, rooting in a plethora of microscopic processes. It is intrins…
Micro- Mechanical assembly of high-quality Fabry-Perot microcavities for the integration with two-dimensional materials
Christoph Rupprecht, Nils Lundt, Sven Höfling +1
Integrating monolayers of two-dimensional semiconductors in planar, and potentially microstructured microcavities is challenging because of the few, available approaches to overgro…
Demonstration of a polariton step potential by local variation of light-matter coupling in a van-der-Waals heterostructure
C. Rupprecht, M. Klaas, H. Knopf +8
The large oscillator strength of excitons in transition metal dichalcogenide layers facilitates the formation of exciton-polariton resonances for monolayers and van-der-Waals heter…
Manipulation of room-temperature Valley-Coherent Exciton-Polaritons in atomically thin crystals by real and artificial magnetic fields
Christoph Rupprecht, Evgeny Sedov, Martin Klaas +11
Strong spin-orbit coupling and inversion symmetry breaking in transition metal dichalcogenide monolayers yield the intriguing effects of valley-dependent optical selection rules. A…
An extension of the projected gradient method to a Banach space setting with application in structural topology optimization
Luise Blank, Christoph Rupprecht
For the minimization of a nonlinear cost functional under convex constraints the relaxed projected gradient process $φ_{k+1} = φ_{k} + α_k(P_H(φ_{k}-λ_k \nabla_H j(φ_{k}))-φ_{k…
Sharp interface limit for a phase field model in structural optimization
Luise Blank, Harald Garcke, Claudia Hecht +1
We formulate a general shape and topology optimization problem in structural optimization by using a phase field approach. This problem is considered in view of well-posedness and…
Multi-material phase field approach to structural topology optimization
Luise Blank, M. Hassan Farshbaf-Shaker, Harald Garcke +2
Multi-material structural topology and shape optimization problems are formulated within a phase field approach. First-order conditions are stated and the relation of the necessary…
Optimal control of Allen-Cahn systems
Luise Blank, M. Hassan Farshbaf-Shaker, Claudia Hecht +2
Optimization problems governed by Allen-Cahn systems including elastic effects are formulated and first-order necessary optimality conditions are presented. Smooth as well as obsta…
