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…
Tracking a Spin-Polarized Superconducting Bound State across a Quantum Phase Transition
Sujoy Karan, Haonan Huang, Alexander Ivanovic +5
The magnetic exchange coupling between magnetic impurities and a superconductor induce so-called Yu-Shiba-Rusinov (YSR) states which undergo a quantum phase transition (QPT) upon i…
Real-Time Tracking of Coherent Oscillations of Electrons in a Nanodevice by Photo-assisted Tunnelling
Yang Luo, Frank Neubrech, Alberto Martin-Jimenez +3
Coherent collective oscillations of electrons excited in metallic nanostructures (localized surface plasmons) can confine incident light to atomic scales and enable strong light-ma…
Universal scaling of tunable Yu-Shiba-Rusinov states across the quantum phase transition
Haonan Huang, Sujoy Karan, Ciprian Padurariu +5
Quantum magnetic impurities give rise to a wealth of phenomena attracting tremendous research interest in recent years. On a normal metal, magnetic impurities generate the correlat…
Imaging and Controlling Coherent Phonon Wave Packets in Single Graphene Nanoribbons
Yang Luo, Alberto Martin-Jimenez, Michele Pisarra +3
The motion of atoms is at the heart of any chemical or structural transformation in molecules and materials. Upon activation of this motion by an external source, several (usually…
