Magnetic Double-Wells: Lower Bounds on Tunneling

Published 17 Nov 2025 in math-ph, cond-mat.mes-hall, math.AP, math.CA, and math.FA | (2511.13470v1)

Abstract: We present lower bounds on tunneling rates in magnetic double well systems for generic values of the coupling constant. This result was recently announced in \cite{FSW24} and complements our recent counter-example construction which exhibits vanishing tunneling for specially-constructed double-well potentials.
