Anionic Character of the Conduction Band of Sodium Chloride
Christopher C. Leon, Abhishek Grewal, Klaus Kuhnke +2
The alkali halides are ionic compounds. Each alkali atom donates an electron to a halogen atom, leading to ions with full shells. The valence band is mainly located on halogen atom…
Character of electronic states in the transport gap of molecules on surfaces
Abhishek Grewal, Christopher C. Leon, Klaus Kuhnke +2
We report on scanning tunneling microscopy (STM) topographs of individual metal phthalocyanines (MPc) on a thin salt (NaCl) film on a gold substrate, at tunneling energies within t…
Single Photon Emission from a Plasmonic Light Source Driven by a Local Field-Induced Coulomb Blockade
Christopher C. Leon, Olle Gunnarsson, Dimas G. de Oteyza +5
A hallmark of quantum control is the ability to manipulate quantum emission at the nanoscale. Through scanning tunneling microscopy induced luminescence (STML) we are able to gener…
Photon super-bunching from a generic tunnel junction
Christopher Leon, Anna Rosławska, Abhishek Grewal +3
Generating correlated photon pairs at the nanoscale is a prerequisite to creating highly integrated optoelectronic circuits that perform quantum computing tasks based on heralded s…
Analytical investigation of singularities in two-particle irreducible vertex functions of the Hubbard atom
Patrik Thunström, Olle Gunnarsson, Sergio Ciuchi +1
Two-particle generalized susceptibilities and their irreducible vertex functions play a prominent role in the quantum many-body theory for correlated electron systems. They act as…
Single charge and exciton dynamics probed by molecular-scale-induced electroluminescence
Anna Rosławska, Pablo Merino, Christoph Große +5
Excitons and their constituent charge carriers play the central role in electroluminescence mechanisms determining the ultimate performance of organic optoelectronic devices. The i…
