Surface reconstruction of tetragonal methylammonium lead triiodide
Azimatu Seidu, Marc Dvorak, Jari Järvi +2
We present a detailed first-principles analysis of the (001) surface of methylammonium lead triiodide (MAPbI3). With density-functional theory we investigate the atomic and electro…
Electronic Characterization of a Charge-Transfer Complex Monolayer on Graphene
Avijit Kumar, Kaustuv Banerjee, Mikko M. Ervasti +5
Organic charge-transfer complexes (CTCs) formed by strong electron acceptor and strong electron donor molecules are known to exhibit exotic effects such as superconductivity and ch…
Nonlocality, entropy creation, and entanglement in quantum many-body systems
Marc Dvorak
We propose a reinterpretation and reformulation of the single-particle Green's function in nonrelativistic quantum many-body theory with an emphasis on normalization. By downfoldin…
Particle conservation in the single-particle Green's function
Marc Dvorak
We argue that the exact single-particle Green's function () in quantum many-body theory does not conserve particle number because the single-particle basis is incomplete. We con…
