Superconductivity Near a Quantum Critical Point: Bounds on the Transition Temperature in the $\gamma$-Model
Closed-form Gershgorin-based upper bounds on the superconducting Tc in the γ-model improve on prior literature, while interlacing-based lower bounds reproduce known results at small truncation size.
