Superconducting landscape of the strongly correlated bilayer Hubbard model

Motoharu Kitatani, Yusuke Nomura, Shiro Sakai +1

Coupling two strongly correlated layers opens a distinct route to repulsion-driven superconductivity. Yet the same interlayer coupling makes the optimization of superconductivity h…

Quadrupolar phase transition in superconducting lanthanum hydride

Abhishek Raghav, Kousuke Nakano, Marco Cherubini +2

Lanthanum hydride (LaH) has been widely studied for its high superconducting critical temperature of 250 K at about 170 GPa pressure. Although the structural -t…

Self-energy pole optimization of superconductivity in the bilayer Hubbard model

Taka-Shi Fujiwara, Shiro Sakai, Ryotaro Arita

We study the real-frequency structure of the self-energy in the bilayer Hubbard model, using the dynamical cluster approximation. At half filling, the Mott insulator-band insulator…

First-principles calculation of coherence length and penetration depth based on density functional theory for superconductors

Mitsuaki Kawamura, Takuya Nomoto, Niklas Witt +1

We develop a first-principles framework for evaluating the fundamental length scales of superconductivity, namely the coherence length and the magnetic penetration depth $λ_\…

Quantum-geometry-driven exact ferromagnetic ground state in a nearly flat band

Taisei Kitamura, Hiroki Nakai, Hosho Katsura +1

We construct a Hubbard model with a nearly flat band whose quantum geometry can be tuned independently of the energy dispersion and the Coulomb interaction. We show that, when the…

Coexisting electronic smectic liquid crystal and superconductivity in a Si square-net semimetal

Christopher J. Butler, Toshiya Ikenobe, Ming-Chun Jiang +6

Electronic nematic and smectic liquid crystals are spontaneous symmetry-breaking phases that are seen to precede or coexist with enigmatic unconventional superconducting states in…
