Resonance widths in a case of multidimensional phase space tunneling
Resonance widths in a case of multidimensional phase space tunneling
Motivated by the study of resonances for molecular systems in the BornāOppenheimer approximation, we consider a semiclassical 2 Ć 2 matrix Schrodinger operator of the form P = āhĪI2 + diag(xn ā Ī¼, ĻV2(x)) + hR(x,hDx), where Ī¼ and Ļ are two small positive constants, V2 is real-analytic and admits ā¦
