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…
Percolative Mott insulator-metal transition in doped SrIrO
Zhixiang Sun, Jose M. Guevara, Steffen Sykora +7
Despite many efforts to rationalize the strongly correlated electronic ground states in doped Mott insulators, the nature of the doping induced insulator to metal transition is sti…
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…
