Analysis of real-space transport channels for electrons and holes in halide perovskites
Frederik Vonhoff, Maximilian J. Schilcher, David R. Reichman +1
Predicting and explaining charge carrier transport in halide perovskites is a formidable challenge because of the unusual vibrational and electron-phonon coupling properties of the…
Charge Density Wave and Ferromagnetism in Intercalated CrSBr
Margalit L. Feuer, Morgan Thinel, Xiong Huang +25
In materials with one-dimensional electronic bands, electron-electron interactions can produce intriguing quantum phenomena, including spin-charge separation and charge density wav…
Benchmarking the Exponential Ansatz for the Holstein model
Junjie Yang, Zhi-Hao Cui, Ankit Mahajan +3
Polarons are quasiparticles formed as a result of lattice distortions induced by charge carriers. The single-electron Holstein model captures the fundamentals of single polaron phy…
Correlated Anharmonicity and Dynamic Disorder Control Carrier Transport in Halide Perovskites
Maximilian J. Schilcher, David J. Abramovitch, Matthew Z. Mayers +3
Halide pervoskites are an important class of semiconducting materials which hold great promise for optoelectronic applications. In this work we investigate the relationship between…
Microscopic Theory of Multimode Polariton Dispersion in Multilayered Materials
Arkajit Mandal, Ding Xu, Ankit Mahajan +3
We develop a microscopic theory for the multimode polariton dispersion in materials coupled to cavity radiation modes. Starting from a microscopic light-matter Hamiltonian, we devi…
Ultrafast imaging of polariton propagation and interactions
Ding Xu, Arkajit Mandal, James M. Baxter +6
Semiconductor excitations can hybridize with cavity photons to form exciton-polaritons (EPs) with remarkable properties, including light-like energy flow combined with matter-like…
