Momentum Structure of Superconductivity and Sublattice Effects from Quasiparticle Interference in CsVSb
Aaron G. Greenberg, Xinze Yang, Junze Deng +11
Quantum interference encoded in the sublattice texture of kagome Bloch wavefunctions has been widely invoked as a route to correlated states, including chiral charge order, unconve…
Quantum geometry and critical temperature enhancement in MgB superconductivity
Yi Jiang, Haoyu Hu, Dumitru Călugăru +13
MgB, a phonon-mediated superconductor with record-high critical temperature K, is revisited to obtain a comprehensive theory of electrons, phonons, and their cou…
Superfluid weight in disordered flat-band superconductors as a competition between localization functionals
Kryštof Kolář, Tero T. Heikkilä, Päivi Törmä
According to Anderson's theorem, the gap of a time-reversal symmetric weak-coupling superconductor is unaffected by non-magnetic disorder. However, the superfluid weight (stiffness…
Theory of dynamical superradiance in organic materials
Lukas Freter, Piper Fowler-Wright, Javier Cuerda +3
We develop the theory of dynamical superradiance -- the collective exchange of energy between an ensemble of initially excited emitters and a single-mode cavity -- for organic mate…
T-matrix representation of optical scattering response: Suggestion for a data format
Nigar Asadova, Karim Achouri, Kristian Arjas +39
The transition matrix, frequently abbreviated as T-matrix, contains the complete information in a linear approximation of how a spatially localized object scatters an incident fiel…
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…
