Emergent BEC mechanism in flat-band superconductors
V. Berger, I. S. Tupitsyn, B. Currie +3
The formation of bound bosonic pairs of fermions, followed by their Bose-Einstein (quasi) condensation (BEC), is a foundational mechanism of superconductivity. At low filling, flat…

Numerically Exact Study of Flat-Band Superconductivity
I. S. Tupitsyn, B. Currie, B. V. Svistunov +2
Current theories of high-temperature superconductivity in flat-band systems predict a linear dependence of the transition temperature on the attractive interaction, …
