Quenched pair breaking by interlayer correlations as a key to superconductivity in La $_{3}$ Ni $_{2}$ O $_{7}$

Siheon Ryee, Niklas Witt, Tim O. Wehling

The recent discovery of superconductivity in La $_{3}$ Ni $_{2}$ O $_{7}$ with $T_{c} ≃ 80 K$ under high pressure opens up a new route to high- $T_{c}$ superconduct…

Bypassing the lattice BCS-BEC crossover in strongly correlated superconductors: resilient coherence from multiorbital physics

Niklas Witt, Yusuke Nomura, Sergey Brener +3

Superconductivity emerges from the spatial coherence of a macroscopic condensate of Cooper pairs. Increasingly strong binding and localization of electrons into these pairs comprom…

No superconductivity in Pb $_{9}$ Cu $_{1}$ (PO $_{4}$ ) $_{6}$ O found in orbital and spin fluctuation exchange calculations

Niklas Witt, Liang Si, Jan M. Tomczak +2

Finding a material that turns superconducting under ambient conditions has been the goal of over a century of research, and recently Pb $_{10 - x}$ Cu $_{x}$ (PO $_{4}$ ) $_{6}$ O aka LK-99 has be…
