Some Quantum Operators with Discrete Spectrum but Classically Continuous Spectrum
A standard rule of thumb about whether a quantum Hamiltonian H = -A + V(x) has purely discrete spectrum or some continuous spectrum is the following. Look at the volume {(p, q) Ip* + V(q) <E} in R*“. If this volume is finite for all E, the standard wisdom is that H has only discrete spectrum. This standard wisdom also says that if this volume is infinite for some E < oo, then the spectrum is no...
متن کاملOperators with Singular Continuous Spectrum
The Baire category theorem implies that the family, F,of dense sets G6 in a fixed metric space, X , is a candidate for generic sets since it is closed under countable intersections; and if X is perfect (has no isolated point), then A E F has uncountable intersections with any open ball in X. There is a long tradition of soft arguments to prove that certain surprising sets are generic. For examp...
متن کاملSchrödinger Operators with Purely Discrete Spectrum
We prove −∆+V has purely discrete spectrum if V ≥ 0 and, for all M , |{x | V (x) < M}| < ∞ and various extensions.

2014 We study Hw = d2/dx2 + VJx) and its discrete analog. For a large class of Vro which are intuitively random but nevertheless deterministic, we prove that is empty. Typical is V(x) = xn(cv)) where f (and thus V) is analytic and is a Poisson process. For example, if f decays exponentially but is not a reflectionless potential, we prove that is empty.

متن کاملSome Schrödinger Operators with Dense Point Spectrum
Given any sequence {En}n−1 of positive energies and any monotone function g(r) on (0,∞) with g(0) = 1, lim r→∞ g(r) = ∞, we can find a potential V (x) on (−∞,∞) so that {En}n=1 are eigenvalues of − d 2 dx2 + V (x) and |V (x)| ≤ (|x| + 1)−1g(|x|). In [7], Naboko proved the following: Theorem 1. Let {κn}∞n=1 be a sequence of rationally independent positive reals. Let g(r) be a monotone function o...
