Systematic dynamical mean-field theory study of 3d perovskite oxides with uniform Coulomb interactions
Antik Sihi, Caden Ginter, Kristjan Haule +1
Strongly correlated transition-metal perovskite oxides pose a fundamental challenge for electronic-structure theory and for large-scale, data-driven materials discovery. While DFT+…
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…
A Topological Superconductor Tuned by Electronic Correlations
Haoran Lin, Christopher L. Jacobs, Chenhui Yan +15
A topological superconductor, characterized by either a chiral order parameter or a chiral topological surface state in proximity to bulk superconductivity, is foundational to topo…
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…
