From weakly interacting spinons to tightly bound triplons in the frustrated quantum spin-Peierls chain
Pyeongjae Park, Bo Xiao, Karolina Górnicka +7
Fractionalized quasiparticles and their confinement into emergent bound states lie at the heart of modern quantum magnetism. While the evolution into magnonic bound states has been…
Defect-induced displacement of topological surface state in quantum magnet MnBiTe
Felix Lüpke, Marek Kolmer, Hengxin Tan +6
The topological magnet MnBiTe (MBT), with gapped topological surface state, is an attractive platform for realizing quantum anomalous Hall and Axion insulator states. Howev…
Real-space visualization of orbital-selective superconductivity in FeSe
Sang Yong Song, Gábor B. Halász, Jiaqiang Yan +2
We investigate the orbitally resolved superconducting properties of bulk FeSe using scanning tunneling microscopy (STM). We find that the spectral weights of both the large a…
Nanoscale control over single vortex motion in an unconventional superconductor
Sang Yong Song, Chengyun Hua, Gábor B. Halász +4
To realize braiding of vortex lines and understand the basic properties of the energy landscape for vortex motion, precise manipulation of superconducting vortices on the nanoscale…
