Holographic Maps of Quasiparticle Interference
Emanuele G. Dalla Torre, Yang He, Eugene Demler
The analysis of Fourier-transformed scanning-tunneling-microscopy (STM) images with subatomic resolution is a common tool for studying properties of quasiparticle excitations in st…
Friedel Oscillations as a Probe of Fermionic Quasiparticles
Emanuele G. Dalla Torre, David Benjamin, Yang He +2
When immersed in a see of cold electrons, local impurities give rise to density modulations known as Friedel oscillations. In spite of the generality of this phenomenon, the exact…
Spin-Polarized Quantum Well States on BiFeSe
Michael M. Yee, Z. -H. Zhu, Anjan Soumyanarayanan +8
Low temperature scanning tunneling microscopy is used to image the doped topological insulator BiFeSe. Interstitial Fe defects allow the detection of quasiparticle…
