Layer-Asymmetry-Induced Topological Superconductivity in High-T$_c$ Bilayer Nickelates

The recent discovery of high-T$_c$ superconductivity in bilayer nickelates has highlighted the crucial role of interlayer coupling and motivated proposals for dominant interlayer pairing. Whether such pairing can support topological superconductivity, however, remains unexplored. Here, we demonstrate that substrate-sup...

Electronic Structures and Orbital-Selective Coherence-Incoherence Crossover in CsFe 2 As 2

Understanding the role of electron correlations in quasiparticle coherence is central to multiorbital iron-based superconductors. Here, we investigate the electronic structure and temperature-dependent quasiparticle dynamics of CsFe$_2$As$_2$ using polarization-resolved laser- and synchrotron-based angle-resolved pho...

Mode-selective phonon effects on magnetism and superconductivity in trilayer nickelates

The discovery of high-$T_c$ superconductivity in multilayer nickelates has stimulated intense interest, yet the microscopic origins of their correlated states remain debated. Recently the observed isotope effect of the magnetic state in trilayer nickelates highlights the important role of lattice vibrations in shaping...
