Magnon-Mediated Superconductivity in a 2D Itinerant Ferromagnet with Weak Easy-plane Magnetic Anisotropy
Vladimir Calvera, Heqiu Li, Yijie Wang +2
Motivated by recent observations of superconductivity in a quarter-metal state of spin- and valley- polarized graphene multilayers, we investigate pairing within a ferromagnetic ph…

Rose Albu Mustaf, Sajilesh K. P., Sanu Mishra +9
We report the experimental discovery of bulk superconductivity in two kagome lattice compounds, YRuB and LuRuB, which were predicted through machine learning-accele…

Ming-Rui Li, Yves H. Kwan, Hong Yao +1
We show the presence of analytic superconducting ground states in the Berry Trashcan -- a minimal model of rhombohedral graphene valid for layers -- under s…

Chao-Xing Liu, B. Andrei Bernevig
In this work, we propose a mechanism of inducing stable nodal superconductivity for multiple-flat-band systems. This mechanism is based on the degenerate flat band nature, so that…

Yi Jiang, Scott B. Lee, Jonah Herzog-Arbeitman +12
In a series of recent reports, doped lead apatite (LK-99) has been proposed as a candidate ambient temperature and pressure superconductor. However, from both an experimental and t…

Nontrivial Quantum Geometry and the Strength of Electron-Phonon Coupling
Jiabin Yu, Christopher J. Ciccarino, Raffaello Bianco +3
The coupling of electrons to phonons (electron-phonon coupling) is crucial for the existence of various phases of matter, in particular superconductivity and density waves. Here, w…

Chao-Xing Liu, Yulin Chen, Ali Yazdani +1
We develop an analytic theory to describe the interaction between electrons and K-phonons and study its influence on superconductivity in the bare bands of twisted bilayer graphene…
Revisiting flat band superconductivity: dependence on minimal quantum metric and band touchings
Kukka-Emilia Huhtinen, Jonah Herzog-Arbeitman, Aaron Chew +2
A critical result in superconductivity is that flat bands, though dispersionless, can still host nonzero superfluid weight due to quantum geometry. We show that the derivation of t…
Superfluidity and Quantum Geometry in Twisted Multilayer Systems

Fragile topology and flat-band superconductivity in the strong-coupling regime
Valerio Peri, Zhida Song, B. Andrei Bernevig +1
In flat bands, superconductivity can lead to surprising transport effects. The superfluid "mobility", in the form of the superfluid weight , does not draw from the curvature o…
Topology-Bounded Superfluid Weight In Twisted Bilayer Graphene
Fang Xie, Zhida Song, Biao Lian +1
While regular flat bands are good for enhancing the density of states and hence the gap, they are detrimental to the superfluid weight. We show that the predicted nontrivial topolo…
