Spectral estimates for a class of Schrodinger operators with infinite phase space and potential unbounded from below
Result description
We analyse two-dimensional Schrodinger operators with the potential vertical bar xy vertical bar(p) - lambda(x(2) + y(2))(p/(p+2)) where p >= 1 and lambda >= 0. We show that there is a critical value of lambda such that the spectrum for lambda < lambda(crit) is bounded below and purely discrete, while for lambda > lambda(crit) it is unbounded from below. In the subcritical case, we prove upper and lower bounds for the eigenvalue sums.
