Topological superconductivity in doped magnetic moiré semiconductors

V Crépel, D Guerci, J Cano, JH Pixley, A Millis - Physical review letters, 2023 - APS
We show that topological superconductivity may emerge upon do** of transition metal
dichalcogenide heterobilayers above an integer-filling magnetic state of the topmost valence …

Magnonic superconductivity

KG Nazaryan, L Fu - Science Advances, 2024 - science.org
We uncover a superconducting state with partial spin polarization induced by a magnetic
field. This state, which we call “magnonic superconductor,” lacks a conventional pairing …

Complex magnetic and spatial symmetry breaking from correlations in kagome flat bands

YP Lin, C Liu, JE Moore - Physical Review B, 2024 - APS
We present the mean-field phase diagram of electrons in a kagome flat band with repulsive
interactions. In addition to flat-band ferromagnetism, the Hartree-Fock analysis yields …

Superconductivity induced by strong electron-exciton coupling in doped atomically thin semiconductor heterostructures

J von Milczewski, X Chen, A Imamoglu, R Schmidt - Physical Review Letters, 2024 - APS
We study a mechanism to induce superconductivity in atomically thin semiconductors where
excitons mediate an effective attraction between electrons. Our model includes interaction …

J Profe, DM Kennes, L Klebl - SciPost Physics Codebases, 2024 - scipost.org
We present divERGe, an open source, high-performance C/C++/Python library for functional
renormalization group (FRG) calculations on lattice fermions. The versatile model interface …

Boundary-obstructed topological superconductor in buckled honeycomb lattice under perpendicular electric field

R Ghadimi, SH Lee, BJ Yang - Physical Review B, 2023 - APS
In this work, we show that a buckled honeycomb lattice can host a boundary-obstructed
topological superconductor (BOTS) in the presence of f-wave spin-triplet pairing (fSTP). The …

Intertwined Superconductivity and Magnetism from Repulsive Interactions in Kondo Bilayers

CS Weber, D Kiese, DM Kennes… - arxiv preprint arxiv …, 2024 - arxiv.org
While superconductors are conventionally established by attractive interactions, higher-

Floquet engineering of effective pairing interactions in a doped band insulator

Y Takahashi, H Miyamoto, K Kuroki… - arxiv preprint arxiv …, 2024 - arxiv.org
We investigate the pairing state in a doped band insulator under a periodic driving field. We
employ a correlated fermionic model on a honeycomb lattice, in which a pairing glue is …

[PDF][PDF] Functional renormalization group developments for correlations in quantum materials

JB Profe - 2023 - publications.rwth-aachen.de
In this thesis we derive a unified truncated unity approximation for functional renormalization
group and related methods. The approximation is applicable to different materials and …
