Origin of sublattice particle-hole asymmetry in monolayer FeSe superconductors
Mercè Roig, Kazi Ranjibul Islam, Basu Dev Oli +7
In iron-based superconductors, the two Fe atoms in the unit cell are typically related by crystal symmetries; therefore, we expect no intra-unit cell variations in the superconduct…
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…
KPROJ: A Program for Unfolding Electronic and Phononic Bands
Jiaxin Chen, M. Weinert, Mingxing Chen
We introduce a program named KPROJ that unfolds the electronic and phononic band structure of materials modeled by supercells. The program is based on the -projection m…
Anisotropic response of defect bound states to magnetic field in epitaxial FeSn films
Huimin Zhang, Zhengfei Wang, Michael Weinert +1
Crystal defects, whether intrinsic or engineered, drive many fundamental phenomena and novel functionalities of quantum materials. Here, we report symmetry-breaking phenomena induc…
