Many-body renormalization of semiconductor quantum wire excitons: absorption, gain, binding, and unbinding.
We consider theoretically the formation and stability of quasi-one-dimensional many-body excitons in GaAs quantum wire structures under external photoexcitation conditions by solving the dynamically screened Bethe-Salpeter equation for realistic Coulomb interaction. In agreement with several recent experimental findings the calculated excitonic peak shows weak carrier-density dependence up to (...
متن کاملMany-body Effects on Excitonic Optical Properties of Photoexcited Semiconductor Quantum Wire Structures
We study carrier interaction induced many-body effects on the excitonic optical properties of highly photoexcited one-dimensional semiconductor quantum wire systems by solving the dynamically screened Bethe-Salpeter equation using realistic Coulomb interaction between carriers. Including dynamical screening effects in the electron/hole self-energy and in the electronhole interaction vertex func...
متن کاملQuantum Many-Body Simulation using Cavity Coupled Monolayer Excitons
We propose an architecture for quantum simulation of strongly interacting bosons using monolayer excitons in MoS2 quantum dots. The strongly coupled monolayer exciton and cavity photon form polaritons between which the interaction reaches 1 ∼ 10 meV—more than one order of magnitude higher than the state-of-art value. We discuss Mott transition in a chain of coupled cavities driven by photon blo...
متن کاملRenormalization of myoglobin-ligand binding energetics by quantum many-body effects.
We carry out a first-principles atomistic study of the electronic mechanisms of ligand binding and discrimination in the myoglobin protein. Electronic correlation effects are taken into account using one of the most advanced methods currently available, namely a linear-scaling density functional theory (DFT) approach wherein the treatment of localized iron 3d electrons is further refined using ...
متن کاملBand gap renormalization in photoexcited semiconductor quantum wire structures in the GW approximation
We investigate the dynamical self-energy corrections of the electron-hole plasma due to electron-electron and electron-phonon interactions at the band edges of a quasi-one dimensional (1D) photoexcited electron-hole plasma. The leading-order GW dynamical screening approximation is used in the calculation by treating electron-electron Coulomb interaction and electron-optical phonon Fröhlich inte...
