| Dec 5, 2023 at 19:40 | comment | added | Christian Remling | Since the potential $V(x)=2q\cosh 2x$ satisfies $\lim_{x\to\pm\infty}V(x)=\infty$, the spectrum is indeed purely discrete and the eigenvalues are positive since $V>0$. I cannot see any reason to expect that these can be found explicitly. | |
