Semiclassical resolvent bounds for compactly supported radial potentials
Kiril Datchev, Jeffrey Galkowski, Jacob Shapiro
We employ separation of variables to prove weighted resolvent estimates for the semiclassical Schrödinger operator in dimension , where ,…

Semiclassical resonance asymptotics for the delta potential on the half line
Kiril Datchev, Nkhalo Malawo
We compute resonance width asymptotics for the delta potential on the half-line, by deriving a formula for resonances in terms of the Lambert W function and applying a series expan…
