| Apr 9, 2017 at 21:21 | comment | added | Math604 | I meant to write $ \mu_2-\mu_1 $ small... okay, thanks for the result. This is what i was looking for. | |
| Apr 9, 2017 at 18:08 | comment | added | Carlo Beenakker | in a symmetric double well potential the difference $|\mu_2-\mu_1|$ is exponentially small in the thickness of the barrier that separates the two wells. | |
| Apr 9, 2017 at 16:48 | comment | added | Math604 | not sure what nearly degenerate eigenvalues means? i assume it means you can make $ \mu_2 = \mu_1$ arbitrarily small? (in any case, no i can't exclude the double well). | |
| Apr 9, 2017 at 13:43 | comment | added | Carlo Beenakker | does "semiconvex" exclude a double-well potential? if it does not, there is nothing from preventing two nearly degenerate eigenvalues, one from each well. | |
