Theory of Electron Spin Resonance in Scanning Tunneling Microscopy
Christian R. Ast, Piotr Kot, Maneesha Ismail +3
Electron spin resonance (ESR) spectroscopy in scanning tunneling microscopy (STM) has enabled probing the electronic structure of single magnetic atoms and molecules on surfaces wi…
Roadmap on Nanoscale Magnetic Resonance Imaging
Raffi Budakian, Amit Finkler, Alexander Eichler +22
The field of nanoscale magnetic resonance imaging (NanoMRI) was started 30 years ago. It was motivated by the desire to image single molecules and molecular assemblies, such as pro…
Surface reconstruction induced anisotropic energy landscape of bismuth monomers and dimers on the Si(001) surface
Haonan Huang, Christian Schön, Christian Ast
Spin qubits have attracted tremendous attention in the effort of building quantum computers over the years. Natural atomic scale candidates are group-V dopants in silicon, not only…
Electric Control of Spin Transitions at the Atomic Scale
Piotr Kot, Maneesha Ismail, Robert Drost +3
Electric control of spins has been a longstanding goal in the field of solid state physics due to the potential for increased efficiency in information processing. This efficiency…
Combining Electron Spin Resonance Spectroscopy with Scanning Tunneling Microscopy at High Magnetic Fields
Robert Drost, Maximilian Uhl, Piotr Kot +8
Magnetic media remain a key in information storage and processing. The continuous increase of storage densities and the desire for quantum memories and computers pushes the limits…
Visualizing the multifractal wavefunctions of a disordered two-dimensional electron gas
Berthold Jäck, Fabian Zinser, Elio J. K\" onig +5
The wavefunctions of a disordered two-dimensional electron gas at the quantum-critical Anderson transition are predicted to exhibit multifractal scaling in their real space amplitu…
Dynamical Coulomb Blockade as a Local Probe for Quantum Transport
Jacob Senkpiel, Jan C. Klöckner, Markus Etzkorn +9
Quantum fluctuations are imprinted with valuable information about transport processes. Experimental access to this information is possible, but challenging. We introduce the dynam…
Modular Arithmetic with Nodal Lines: Drumhead Surface States in ZrSiTe
Lukas Muechler, Andreas Topp, Raquel Queiroz +5
We study the electronic structure of the nodal line semimetal ZrSiTe both experimentally and theoretically. We find two different surface states in ZrSiTe - topological drumhead su…
Signatures of phase-coherent transport and the role of quantum fluctuations in the dynamical Coulomb blockade regime
Berthold Jäck, Jacob Senkpiel, Markus Etzkorn +3
Josephson junctions operated in the dynamical Coulomb blockade regime recently gained an significant amount of attention as central building block in concepts to demonstrate the no…
Surface band structure of (111)
Hadj M. Benia, Carola Straßer, Klaus Kern +1
Theoretical and experimental studies agree that () to be a three-dimensional topological insulator. However, there is still a…
Origin of Rashba-splitting in the quantized subbands at Bi2Se3 surface
H. M. Benia, A. Yaresko, A. P. Schnyder +4
We study the band structure of the topological insulator (111) surface using angle-resolved photoemission spectroscopy. We examine the situation where two…
Spin properties of 2D semiconductors probed by scanning tunneling microscopy
M. Morgenstern, A. Georgi, C. Straßer +3
The interrelation between spin and charge in semiconductors leads to interesting effects, e.g., the Rashba-type spin-orbit splitting or the exchange enhancement. These properties a…
Reactive chemical doping of the topological insulator

Using angle resolved photoemission spectroscopy we studied the evolution of the surface electronic structure of the topological insulator as a function of…
The Structural Influence on the Rashba-type Spin-Splitting in Surface Alloys
Isabella Gierz, Benjamin Stadtmüller, Johannes Vuorinen +5
The Bi/Ag(111), Pb/Ag(111), and Sb/Ag(111) surface alloys exhibit a two-dimensional band structure with a strongly enhanced Rashba-type spin-splitting, which is in part attributed…
