Symmetry-required Orbital Selectivity in Monolayer FeSe
Mercè Roig, Qiang Zou, Basu Dev Oli +6
Orbital-selective correlations have been observed to play an important role in Fe-based superconductors. Here, in contrast to previous site-local Mott transition-based origins, we…
Correlation Enhanced Electron-Phonon Coupling in FeSe/SrTiO at a Magic Angle
Qiang Zou, Antik Sihi, Basu Dev Oli +5
While a predictive theory for unconventional superconductivity in Fe-based superconductors remains elusive, an extensively debated aspect is the interaction between phonons and str…
Light-driven lattice metastability for enhanced superconductivity in FeSe/SrTiO3
Qiang Zou, Zhan Su, Andres Tellez Mora +11
Driven quantum materials with on demand properties controlled by external stimuli are critical for emergent quantum technology. In optically tunable superconducting heterostructure…
Unraveling Enhanced Superconductivity in Single-layer FeSe through Substrate Surface Terminations
Qiang Zou, Gi-Yeop Kim, Jong-Hoon Kang +7
Single-layer FeSe films grown on (001) SrTiO3 substrates have shown a significant increase in superconducting transition temperature compared to bulk FeSe. Several mechanisms have…
