Magnetic Field Walls in Flat-band Superconductors
Guodong Jiang, Aaron Dunbrack, Tero T. Heikkilä +1
Superconductors of different types have distinct magnetic properties; for example, they can form Abrikosov vortices or alternating normal-superconducting domains. We predict that,…
Ideal quantum geometry of the surface states of rhombohedral graphite and its effects on the surface superconductivity
Guodong Jiang, Tero Heikkilä, Päivi Törmä
The interplay of quantum geometry and interactions determines the correlated state properties of flat bands. Here, we investigate the ideal quantum geometry (IQG), i.e., the proper…
Superfluid weight cross-over and critical temperature enhancement in singular flat bands
Guodong Jiang, Päivi Törmä, Yafis Barlas
Non-analytic Bloch eigenstates at isolated band degeneracy points exhibit singular behavior in the quantum metric. Here, a description of superfluid weight for zero-energy flat ban…
Geometric superfluid weight of composite bands in multiorbital superconductors
Guodong Jiang, Yafis Barlas
The superfluid weight of an isolated flat band in multi-orbital superconductors contains contributions from the band's quantum metric and a lattice geometric term that depends on t…
