Direct probing of a large spin-orbit coupling in the FeSe superconducting monolayer on STO: Evidence for nontrivial topological states
Khalil Zakeri, Dominik Rau, Jasmin Jandke +3
In condensed-matter physics spin-orbit coupling (SOC) is a fundamental physical interaction, which describes how the electrons' spin couples to their orbital motion. It is the sour…
Direct evidence of a charge depletion region at the interface of Van der Waals monolayers and dielectric oxides: The case of superconducting FeSe/STO
Khalil Zakeri, Dominik Rau, Janek Wettstein +5
The discovery of two dimensional Van der Waals materials has opened up several possibilities for designing novel devices. Yet a more promising way of designing exotic heterostuture…
Metal to insulator transition at the surface of thin films: an in-situ view
Marco Caputo, Jasmin Jandke, Edoardo Cappelli +12
has long been studied as a prototypical strongly correlated material. The difficulty in obtaining clean, well ordered surfaces, however, hindered the use of surface sensit…
Multiple mobile excitons manifested as sidebands in quasi-one-dimensional metallic TaSe3
Junzhang Ma, Simin Nie, Xin Gui +22
Charge neutrality and their expected itinerant nature makes excitons potential transmitters of information. However, exciton mobility remains inaccessible to traditional optical ex…
Spin fluctuation induced Weyl semimetal state in the paramagnetic phase of EuCdAs
J. -Z. Ma, S. M. Nie, C. J. Yi +22
Weyl fermions as emergent quasiparticles can arise in Weyl semimetals (WSMs) in which the energy bands are nondegenerate, resulting from inversion or time-reversal symmetry breakin…
Orbitally resolved superconductivity in real space: FeSe
Fang Yang, Jasmin Jandke, Peter Adelmann +7
Multi-orbital superconductors combine unconventional pairing with complex band structures, where different orbitals in the bands contribute to a multitude of superconducting gaps.…
Anisotropic Correlated Electronic Structure of Colossal Thermopower Marcasite FeSb
A. Chikina, J. -Z. Ma, W. H. Brito +9
Iron antimonide (FeSb) is a mysterious material with peculiar colossal thermopower of about mV/K at 10 K. However, a unified microscopic description of this phenomenon is…
Cooling a polaronic liquid: Phase mixture and pseudogap-like spectra in superconducting
M. Naamneh, M. Yao, J. Jandke +17
Many complex electronic systems exhibit so-called pseudogaps, which are poorly-understood suppression of low-energy spectral intensity in the absence of an obvious gap-inducing sym…
Unconventional pairing in single FeSe layers
Jasmin Jandke, Fang Yang, Patrik Hlobil +6
The pairing mechanism in iron-based superconductors is believed to be unconventional, i.e. not phonon-mediated. The achieved transition temperatures Tc in these superconductors are…
Tracing the electronic pairing glue in unconventional superconductors via inelastic Scanning Tunneling Spectroscopy
Patrik Hlobil, Jasmin Jandke, Wulf Wulfhekel +1
The origin of Cooper pairing in high-temperature superconductors, such as the copper-oxide and iron-based system, is still under debate. High transition temperatures together with…
Scanning Tunneling Spectroscopy on SrFe(AsP)
Jasmin Jandke, Petra Wild, Michael Schackert +5
We investigated SrFe(AsP) single crystals with four different phosphorus concentrations x in the superconducting phase (x =…
Coupling to real and virtual phonons in tunneling spectroscopy of superconductors
Jasmin Jandke, Patrik Hlobil, Michael Schackert +2
Fine structures in the tunneling spectra of superconductors have been widely used to identify fingerprints of the interaction responsible for Cooper pairing. Here we show that for…
Local measurement of the Eliashberg function of Pb islands: enhancement of electron-phonon coupling by quantum well states
Michael Schackert, Tobias Märkl, Jasmin Jandke +5
Inelastic tunneling spectroscopy of Pb islands on Cu(111) obtained by scanning tunneling microscopy below 1K provides a direct access to the local Eliashberg function of the island…
