The electrostatic potential of atomic nanostructures on a metal surface
Rustem Bolat, Jose M. Guevara, Philipp Leinen +9
The discrete and charge-separated nature of matter - electrons and nuclei - results in local electrostatic fields that are ubiquitous in nanoscale structures and are determined by…

Spectroscopic evidence of nematic fluctuations in LiFeAs
Zhixiang Sun, Pranab Kumar Nag, Steffen Sykora +8
The role of nematic fluctuations in the pairing mechanism of iron-based superconductors is frequently debated. Here we present a novel method to reveal such fluctuations by identif…

Spin-polaron ladder spectrum of the spin-orbit-induced Mott insulator SrIrO probed by scanning tunneling spectroscopy
Jose M. Guevara, Zhixiang Sun, Ekaterina M. Pärschke +8
The motion of doped electrons or holes in an antiferromagnetic lattice with strong on-site Coulomb interactions touches one of the most fundamental open problems in contemporary co…
